2e36dbe1a6 Use EVUTIL_ASSERT() consistently instead of assert.

d8164d0cfc Fix win32 connect() event handling. 
Christopher Davis reported:

    Connection failures aren't reported on Windows when
    using bufferevent_socket_connect, because Windows uses
    select's exceptfds to notify of failure, and libevent
    treats them like read events. Only the write event
    handler is currently used to handle connection events.

We should think hard about this one, since it changes
behavior from 1.4.x.  Anything that worked on Mac/Unix before
will work more consistently on Windows now... but this might
break stuff that worked only on Windows, but nowhere else.

Patch from Chris Davis.

6b22e74aa1 Add locking to event_base_loop. 
This is harder than it sounds, since we need to make sure to
release the lock around the key call to the kernel (e.g.,
select, epoll_wait, kevent), AND we need to make sure that
none of the fields that are used in that call are touched by
anything that might be running concurrently in another
thread.  I managed to do this pretty well for everything but
poll().  With poll, I needed to introduce a copy of the
event_set structure.

This patch also fixes a bug in win32.c where we called
realloc() instead of mm_realloc().

cdaca02c29 Activate fd events in a pseudorandom order on older backends. 
New backends like poll and kqueue and so on add fds to the queue in
the order that they are triggered.  But the select backend currently
activates low-numbered fds first, whereas the poll and win32 backends
currently favor whatever fds have been on for the longest.  This is no
good for fairness.

8c66eb2e9b Try to contain the failure when we are running without socketpair(). 
Some win32 systems (mostly those using Kaspersky, it would seem)
prevent us from faking socketpair().  This makes our signal
notification code just not work.  Our response since 1.4 has been to
assert.  For users who would rather work without signals than not work
at all, this has been a regression from 1.3e.

This patch makes adding signal events fail in this case; there's no
reason to kill the whole process.

a) this is 2009
b) niels and nick have been comaintainers for a while
c) saying "all rights reserved" when you then go on to explicitly
   disclaim some rights is sheer cargo-cultism.
