Change event_base.activequeues to "array of eventlist".
Previously, event_base.activequeues was of type "array of pointers to
eventlist." This was pointless: none of the eventlists were allowed
to be NULL. Worse, it was inefficient:
- It made looking up an active event queue take two pointer
deferences instead of one, thus risking extra cache misses.
- It used more RAM than it needed to, because of the extra pointer
and the malloc overhead.
Also, this patch fixes a bug where we were saying
calloc(N,N*sizeof(X)) instead of calloc(N,sizeof(X)) when allocating
activequeues. That part, I'll backport.
Also, we warn and return -1 on failure to allocate activequeues,
rather than calling event_err.

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.

Make event_del(E) block while E is running in another thread.
This gives you the property that once you have called event_del(E),
you know that E is no longer running or pending or active at all, and
so it is safe to delete the resource used by E's callback.

This is one of those patches which will either make matters far
simpler after the bugs shake out, or will get reverted pretty quick
once we realize that it is a stupid idea.
We now post-process the config.h file into a new event-config.h file,
whose macros are prefixed with _EVENT_ and which is thus safe for
headers to include. Using this, we can define replacement timeval
manipulation functions in evutil.h, and use them uniformly through our
code. We can also detect which headers are needful in event.h, and
include them as required.
This is also the perfect time to remove the long-deprecated acconfig.h
file, so that autoheader no longer warns.
Should resolve the following issues:
[ 1826530 ] Header files should have access to autoconf output.
[ 1826545 ] acconfig.h is deprecated.
[ 1826564 ] On some platforms, event.h can't be included alone.
