[core] re-order fields in struct event for memory efficiency
The sizeof `struct event` can reduced on both 32 bit and 64 bit systems
by moving the 4 bytes that make up `ev_events` and `ev_res` below `ev_fd`,
before `struct event_base * ev_base;` since our compiler wouldn't dare do
such a thing (it instead will pad twice, whereas it only needs to be padded
once)

```C
struct event {
                                                         /*  OFFS |  SZ   Bytes  | Total Bytes | START - END  */
    struct event_callback ev_evcallback;                 /*   0x0 |  40          | 40          | 0x0   - 0x28 */

    union {                                              /*  0x28 |  ----------- | ----------- | ------------ */
        TAILQ_ENTRY(event) ev_next_with_common_timeout;  /*       |       ((16)) |             |              */
        int min_heap_idx;                                /*       |       ((04)) |             |              */
    }   ev_timeout_pos;                                  /*       |  16          | 56          | 0x28  - 0x38 */
    int ev_fd;                                           /*  0x38 |  04          | 60          | 0x38  - 0x3c */
```

Since the next field is 8 bytes in length, and we are up to 60 bytes, `ev_fd` ends up being padded (4 more bytes on 64b).

```C
                              /* --- 1 byte gap HERE --->            1           | <61>                      */
                              /* --- 1 byte gap HERE --->            1           | <62>                      */
                              /* --- 1 byte gap HERE --->            1           | <63>                      */
                              /* --- 1 byte gap HERE --->            1           | <64>                      */
    struct event_base * ev_base;                         /*  0x3c |  8           | 68         | 0x3c - 0x40  */
    union {                                              /*  0x40 | ------------ | ---------- | ------------ */
        struct {                                         /*       | ------------ |            |              */
            LIST_ENTRY (event) ev_io_next;               /*       |       ((16+  |            |              */
            struct timeval ev_timeout;                   /*       |         16)) |            |              */
        } ev_io;                                         /*       | ((32))       |            |              */
        struct {                                         /*       | ------------ |            |              */
            LIST_ENTRY (event) ev_signal_next;           /*       |      ((16+   |            |              */
            short   ev_ncalls;                           /*       |        02+   |            |              */
            short * ev_pncalls;                          /*       |        08))  |            |              */
        } ev_signal;                                     /*       | ((26))       |            |              */
    } ev_;                                               /*  0x60 | 32           | 100        | 0x40 - 0x60  */

    short ev_events;                                     /*  0x60 | 2            | 102        | 0x60 - 0x62  */
    short ev_res;                                        /*  0x62 | 2            | 104        | 0x62 - 0x64  */
```

We now hit another line, `struct timeval` is 16 bytes on 64b arch, so we have 4 more bytes
of padding on `ev_res`.

```C
    /* --- 1 byte gap HERE --- */
    /* --- 1 byte gap HERE --- */
    /* --- 1 byte gap HERE --- */
    /* --- 1 byte gap HERE --- */
    struct timeval ev_timeout;                           /*  0x64 | 16           | 120        | 0x64 - 0x74  */
};
```

After moving `ev_events` and `ev_res` below `ev_fd` we have something
a bit more optimal:

```C
struct event2 {
                                                         /*  OFFS |  SZ / Bytes  | RSUM Bytes | START - END  */
    struct event_callback ev_evcallback;                 /*   0x0 | 40           | 40         | 0x0   - 0x28 */
    union {                                              /*  0x28 | ------------ | ---------- | ------------ */
        TAILQ_ENTRY(event) ev_next_with_common_timeout;  /*       |       ((16)) |            |              */
        int min_heap_idx;                                /*       |       ((04)) |            |              */
    } ev_timeout_pos;                                    /*       | 16           | 56         | 0x28  - 0x38 */
    int ev_fd;                                           /*  0x38 | 4            | 60         | 0x38  - 0x3c */
    short ev_events;                                     /*  0x3c | 2            | 62         | 0x3c  - 0x3e */
    short ev_res;                                        /*  0x3e | 2            | 64         | 0x3e  - 0x40 */

    struct event_base * ev_base;                         /*  0x40 | 8            | 74         | 0x40  - 0x48 */
    union {                                              /*  0x48 | ------------ | ---------- | ------------ */
        struct {                                         /*       | ------------ |            |              */
            LIST_ENTRY (event) ev_io_next;               /*       |        ((16+ |            |              */
            struct timeval ev_timeout;                   /*       |         16)) |            |              */
        } ev_io;                                         /*       | ((32))       |            |              */
        struct {                                         /*       | ------------ |            |              */
            LIST_ENTRY (event) ev_signal_next;           /*       |       ((16+  |            |              */
            short   ev_ncalls;                           /*       |         02+  |            |              */
            short * ev_pncalls;                          /*       |         08)) |            |              */
        } ev_signal;                                     /*       | ((26))       |            |              */
    } ev_;                                               /*       | 32           | 106        | 0x48 - 0x68  */
    struct timeval ev_timeout;                           /* 0x68  | 16           | 120        | 0x68 - 0x78  */
};
```

We still have a gap here, but the first was removed.

Again, we can save 8 bytes on both 32 and 64 word sizes (32/64 byte cacheline).

Below are the results for testing v2.1.6 -> master -> master + this patch (Release/-O3)

Code:

```C
  #include <event2/event.h>

  int
  main(int argc, char ** argv) {
      printf("%zu\n", event_get_struct_event_size());
      return 0;
  }
```

81b6209e10 Fix event_dlist definition when sys/queue not included
This header adds TAILQ_HEAD and TAILQ_ENTRY if sys/queue is not included.
There is a similar macro that adds LIST_ENTRY but not LIST_HEAD, even though
LIST_HEAD is used later.

This change pulls in the correct definition (swiped from sys/queue) for
LIST_HEAD and cleans up the one spot where it is used.  The change can be
tested by adding

	#undef LIST_HEAD
	#undef LIST_ENTRY

right before the #ifndef checks and removing

	#define EVENT_DEFINED_LISTENTRY_
	#define EVENT_DEFINED_LISTHEAD_

so that the macros persist later.

Nick Mathewson
745a63dba3 Add "active later" event_callbacks to supersede deferred
An event or event callback can now be in an additional state: "active
later".  When an event is in this state, it will become active the
next time we run through the event loop.  This lets us do what we
wanted to with deferred callbacks: make a type of active thing that
avoids infinite circular regress in a way that starves other events or
exhausts the stack.  It improves on deferred callbacks by respecting
priorities, and by having a non-kludgy way to avoid event starvation.

cba59e5325 Refactor the callback part of an event into its own event_callback type
This shouldn't have any visible effect, but it's necessary or
advisible for a few changes and cleanups I would like to make,
including:
   * Replacing the deferred queue with a type that works more as if it
     were an event.
   * Introducing a useful "activate this on the next round through the
     event loop" state for events and deferreds.
   * Adding an "on until further notice" status for events, to allow a
     saner win32-hybrid approach.
   * Eventually, making all user callbacks first-class things with
     event-like semantics.

cb9da0bf38 Fix all identifiers with names beginning with underscore.
These are reserved in C.  We'd been erroneously using them to indicate
internal use.

Instead, we now use a trailing underscore whenever we'd been using a leading
underscore.

This is an automatic conversion.  The script that produced was made by
running the following script over the output of

 git ls-tree -r --name-only HEAD | grep  '\.[ch]$' | \
   xargs ctags --c-kinds=defglmpstuvx -o - | grep '^_' | \
   cut -f 1 | sort| uniq

(GNU ctags was required.)

3f8c7cd035 Convert include-guard macro convention to avoid reserved identifiers
Previously we used include-guards with names like _EVENT2_EVENT_H_.
But C reserves macros beginning with an underscore for use by the
system.  This patch converts all include guards for files like
include/event2/<fname.h> to be of form EVENT2_<FNAME_H>_INCLUDED_,
and all Libevent 1.x headers in include/<fname.h> to be of the form
EVENT1_<FNAME_H>_INCLUDED_, and all internal libevent headers with
names like <fname.h> to the form <FNAME_H>_INCLUDED_.

FNAME_H is here derived from fname.h by replacing every
non-macro-usable character in fname.h with an underscore, and
putting every remaining character in uppercase.

This is an automatic conversion.  The script that produced was made by
running the following script over all header files:

=====
#!/usr/bin/perl -w

# Run this on every .h file except config.h, sys/queue.h, WIN32/event2/event-config.h

use strict;

my %macros = ();
my %skipped = ();
FILE: for my $fn (@ARGV) {
    my $f = $fn;
    if ($fn !~ /^\.\//) {
	$f = "./$fn";
    }
    if ($f eq './config.h' or
	$f =~ m#/tree.h$# or
	$f =~ m#/queue.h# or
	$f =~ m#/event-config.h# or
	$f =~ m#/evconfig-private.h#) {
	$skipped{$fn} = 1;
	next FILE;
    }
    $skipped{$fn} = 0;
    open(F, $fn);
    while (<F>) {
	if (/^#ifndef ([A-Za-z0-9_]+)/) {
	    $macros{$fn} = $1;
	    next FILE;
	}
    }
}

print "#!/usr/bin/perl -w -i -p\n\n";
for my $fn (@ARGV) {
    if (! exists $macros{$fn}) {
	print "# No macro known for $fn!\n" if (!$skipped{$fn});
    } else {
	if ($macros{$fn} !~ /_H_?$/) {
	    print "# Weird macro for $fn...\n";
	}
	my $goodmacro = uc $fn;
	$goodmacro =~ s#^\./##;
	$goodmacro =~ s#INCLUDE/EVENT2#EVENT2#;
	$goodmacro =~ s#INCLUDE/#EVENT1_#;
	$goodmacro =~ s#TEST/##;

	$goodmacro =~ s#[\/\-\.]#_#g;

	print "s/(?<![A-Za-z0-9_])$macros{$fn}(?![A-Za-z0-9_])/${goodmacro}_INCLUDED_/g;\n"
    }
}
=== And then running the script below that it generated over all
=== the .h files again

68120d9b00 Convert event-config.h macros to avoid reserved identifiers
C reserves all identifiers beginning with an underscore for system
use.  But we had been mangling our autoconf identifiers with the
prefix "_EVENT_" to avoid conflict with other programs.

Instead, we will now use the prefix "EVENT__".  With any luck, the
double-underscore will still hint "here be dragons" to anybody
tempted to think that event-config.h is a stable api.

This is an automatically generated patch.  The script that produced
it was made by running this script over config.h.in:

=====

#!/usr/bin/perl -w

# Run this on config.h.in

use strict;

my %macros = ();

while (<>) {
    if (/^# *undef +([A-Za-z0-9_]+)/) {
	$macros{$1} = 1;
    }
}

print "#!/usr/bin/perl -w -i -p\n\n";
for my $k (sort keys %macros) {
    print "s/(?<![A-Za-z0-9_])_EVENT_$k(?![A-Za-z0-9_])/EVENT__$k/g;\n";
}

== And the script that it generated was then run over all .c and .h files:
#!/usr/bin/perl -w -i -p

604569bf3f Remove the eventqueue list and the ev_next pointers.
Those pointers were once used to maintain a complete list of
inserted IO and signal events.  But such a list is now available by
walking over ev_io_map and ev_signal_map!  So all they did was
require extra pointer operations to maintain, and extra 8-16 bytes
of storage in each struct event.

To be cowardly and keep the option of going back to having this
redundancy, I'm wrapping the removed code in a set of ifdefs.

This is a first cut; it needs cleanups and stress-testing!!  In
particular, it just plain disables a couple of functions that could
probably be saved.

There seems to be a need for an evmap_{io,signal}_foreach() or something.

ca9048f12c Move evkeyvalq into a separate header for evhttp_parse_query users
The evhttp_parse_query API is a bit misdesigned; all the other
evkeyvalq stuff is abstract and lets you get away with having a header
stub, but evhttp_parse_query seems to require that you instantiate an
empty evkeyvalq of your own.

60433a0a1a Clean up syntax on TAILQ_ENTRY() usage
Though the C standards allow it, it's apparently possible to get MSVC
upset by saying "struct { int field; } (declarator);" instead of
"struct {int field; } declarator;", so let's just not do that.

This change means that all required include files are in event2, and
all files not in event2/* are optional.

6494772e32 Use LIST rather than TAILQ for evmap_io and evmap_signal
These structures used TAILQ for the lists of events waiting on a
single fd or signal.  But order doesn't matter for these lists; only
the order of the active events lists actually matters.

f9db33d15d Add LIST_ delaration to event_struct.h to supplment TAILQ_
Generally, LIST_ can be a little faster than TAILQ_ for most
operations.  We only need to use TAILQ_ when we care about traversing
lists from tail-to-head, or we need to be able to add items to the end
of the list.

da6135e356 Reduce windows header includes in our own headers.
It turns out that absolutely everything that was including
windows.h was doing so needlessly; our headers don't need it,
so we should just include winsock2.h (since that's where
struct timeval is defined).

Pre-2.0 code will use the old headers, which include windows.h
for them, so we aren't breaking source compatibility with 1.4.

This solves the bug where we were leaving WIN32_LEAN_AND_MEAN
defined, in roughly the same way that buying an automobile
solves the question of what to give your coachman for boxing
day.

f6b269498a Deprecate EVENT_FD and EVENT_SIGNAL.
These are old aliases for event_get_fd and event_get_signal, and they
haven't been the preferred way of doing things since 2.0.1-alpha.

For a while, we made them use struct event if it was included, but call
event_get_(fd|signal) if it wasn't.  This was entirely too cute.

693c24ef9d Implement queued timeouts for case where many timeouts are the same.
Libevent's current timeout code is relatively optimized for the
randomly scattered timeout case, where events are added with their
timeouts in no particular order.  We add and remove timeouts with
O(lg n) behavior.

Frequently, however, an application will want to have many timeouts
of the same value.  For example, we might have 1000 bufferevents,
each with a 2 second timeout on reading or writing.  If we knew this
were always the case, we could just put timeouts in a queue and get
O(1) add and remove behavior.  Of course, a queue would give O(n)
performance for a scattered timeout pattern, so we don't want to
just switch the implementation.

This patch gives the user the ability to explicitly tag certain
timeout values as being "very common".  These timeout values have a
cookie encoded in the high bits of their tv_usec field to indicate
which queue they belong on.  The queues themselves are each
triggered by an entry in the minheap.

See the regress_main.c code for an example use.

Stop pretending that u_char and u_short are standard types that win32 is dumb not to have.  In fact, u_char can really just be spelled out, and u_short was usually just a bad way of saying ev_uint16_t.
