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.

de069b9977 On win32, errno is not the last socket error. Worse, WSAGetLastError() is not the last socket error sometimes (i.e., EWOULDBLOCK). Also, strerror() does not handle winsock errors. Therefore, event_err() and event_warn() are completely wrong for windows socket errors. Fix that.
