747331d164 Add freeze support to evbuffers.
From the documentation:
   Prevent calls that modify an evbuffer from succeeding. A buffer may
   frozen at the front, at the back, or at both the front and the back.

   If the front of a buffer is frozen, operations that drain data from
   the front of the buffer, or that prepend data to the buffer, will
   fail until it is unfrozen.   If the back a buffer is frozen, operations
   that append data from the buffer will fail until it is unfrozen.

We'll use this to ensure correctness on an evbuffer when we're waiting
for an overlapped IO call to finish.

f1b1bad415 Make the new evbuffer callbacks use a new struct-based interface.
The old interface would fail pretty hard when we had to batch up
multiple adds and drains in a single call.

f90500a5df Add a new improved search function.
The old evbuffer_find didn't allow iterative searching, and forced us
to repack the buffer completely every time we searched in it.  The
new evbuffer_search addresses both of these.  As a side-effect, the
evbuffer_find implementation is now a little more efficient.

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.

81dd04a726 Add a "flags" field to evbuffer callbacks.
For now, there is just one: enabled.  This lets us avoid lots of
mallocs/frees/tailq-manipulations just to turn a callback on and off.
The revised bufferevent code wants this.

de7f7a84a3 Remove in_callbacks check: allow full recursion in evbuffer callbacks. If you get yourself in an infinite loop, that's not our fault. Note this in the docs. Also reindent some docs now that my tabs match Niels's.

Stop pretending that u_char and u_short are standard types that win32 is dumb not to have.  In fact, u_char can really just be spelled out, and u_short was usually just a bad way of saying ev_uint16_t.

Make offsetof into evutil_offsetof.  Be a little more willing to call evbuffer_chain_align() from evbuffer_expand().  Clarify some docs, and add some XXX comments to note questionable areas.
