236403cc4d r5195: most events don't need the time of the event, so save a gettimeofday() call
and just use timeval_current() when its actually needed

d7b4b6de51 r5185: make all the events data structures private to events.c. This will
make it possible to add optimisations to the events code such as
keeping the next timed event in a sorted list, and using epoll for
file descriptor events.

I also removed the loop events code, as it wasn't being used anywhere,
and changed timed events to always be one-shot (as adding a new timed
event in the event handler is so easy to do if needed)

cf11d05e35 r5126: the composite code is no longer client specific or smb specific, so
rename the core structure to composite_context and the wait routine to
composite_wait() (suggestion from metze)

7f981b9ed9 r4944: every event_add_*() caller was having to call talloc_steal() to take
control of the event, so instead build that into the function. If you
pass NULL as mem_ctx then it leaves it as a child of the events
structure.

a3c7417cfe r4943: Smplified the events handling code a lot. The first source of
complexity was that events didn't automatically cleanup
themselves. This was because the events code was written before we had
talloc destructors, so you needed to call event_remove_XX() to clean
the event out of the event lists from every piece of code that used
events. I have now added automatic event destructors, which in turn
allowed me to simplify a lot of the calling code.

The 2nd source of complexity was caused by the ref_count, which was
needed to cope with event handlers destroying events while handling
them, which meant the linked lists became invalid, so the ref_count ws
used to mark events for later destruction.

The new system is much simpler. I now have a ev->destruction_count,
which is incremented in all event destructors. The event dispatch code
checks for changes to this and handles it.

comments welcome, but please think about the alternatives first :-)
