ec347b9225 Move event-config.h to include/event2
This change means that all required include files are in event2, and
all files not in event2/* are optional.

c16e68448c Rename current_base symbol to event_global_current_base_
The "current_base" symbol was never actually declared in an exported
header; it's hideously deprecated, and it was the one remaining
exported symbol (fwict) that was prefixed with neither ev nor
bufferevent nor _ev nor _bufferevent.

codesearch.google.com turns up no actual attempts to use our
current_base from outside libevent.

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.

cd17c3acd5 Add support for a "debug mode" to try to catch common errors.
Right now it only catches cases where we aren't initializing events,
or where we are re-initializing events without deleting them first.
These are however shockingly common.

0683950384 Functions to access more fields of struct event.
Once event_assign() or event_new() had been called, there was no way
to get at a copy of the event's callback, callback argument, or
configured events.  This patch adds an accessor function for each, and
an all-fields accessor for code that wants to re-assign one field of
an event.

This patch also adds a function to return sizeof(struct event), so
that code with intense RAM needs can still retain ABI compatibility
between versions of Libevent without having to heap-allocate every
struct event individually.

The code here was first proposed by Pavel Pisa.

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.

b73ad7bc45 Treat the bitwise OR of two enum values as an int.
This makes our interfaces usable from C++, which doesn't believe
you can say    "bufferevent_socket_nase(base, -1,
BEV_OPT_CLOSE_ON_FREE|BEV_OPT_DEFER_CALLBACKS)" but which instead
would demand "static_cast<bufferevent_options>(BEV_OPT_CLOSE_ON_FREE|
BEV_OPT_DEFER_CALLBACKS))" for the last	argument.

eb97bb76e1 Make the headers compile happily with pedantic C compilers.
Original message from SF patch 2797966:

    While commas at the end of enumerator lists are valid in c99, they
    are not valid +in c89 nor in c++. When using gcc/g++ with the
    -pedantic flag, users will +receive a warning (gcc) or an
    error(g++) when including the event2/event.h and
    +event2/bufferevent.h. The errors look something like

    event2/event.h:159: error: comma at end of enumerator list
