f8b527e6a1 Fix a dumb bug where we would allocate too little memory in event_get_supported_methods().

b06b2649b4 Make "deferred callback queue" independent of event_base. 
This way, we can more easily have an IOCP bufferevent implementation
that does not need an event_base at all.  Woot.

1fb2e818a6 Use a uniform strategy when a function is not working: do not expose 
it.

Rather than failing at runtime, it is better to fail at compile or
link time.

9fcd84d196 Include disabled methods in event_get_supported_methods() output. 
Previously, events that were disabled using EVENT_NO* were left out of
event_get_supported_methods().  This was wrong, broke unit tests
(under some circumstances) and left the user with no good way to tell
which methods were actually compiled in.

Fixes bug 2821015.

6b4b77a265 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.

4868f4d217 Initial support for a lightweight 'deferred callbacks'. 
A 'deferred callback' is just a function that we've queued in the
event base.  This ability is needed for some mt stuff, and for complex
callback chains.  For internal use only.

e3d82497c9 Don't allow internal events to starve lower-priority events. 
This is exceptionally important with multithreaded stuff, where we use
an event to notify the base that other events have been made active.
If the activated events have a prioirty number greater than that of the
notification event, it will starve them, and that's no good.

b85b710cf5 Update copyright statements to reflect the facts that: 
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.
