Change event_base.activequeues to "array of eventlist".

Previously, event_base.activequeues was of type "array of pointers to

to be NULL.  Worse, it was inefficient:

  - It made looking up an active event queue take two pointer

Make persistent timeouts more accurate.

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.
