8a99083f01 Add an evbuffer_search_range() to search a bounded range of a buffer 
This can be handy when you have	one search to find the end of a	header
section, and then you want to find a substring within the header
section without looking at the body.

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.

bba69e03f8 New semantics for evbuffer_cb_set_flags(). 
Previously, set_flags() would replace all previous user-visible flags.
Now it just sets the flags, and there is a clear_flags() function to
clear other flags.

ec6bfd0335 Fix for evbuffer_read() when all data fits in penultimate chain. 
Previously we were reading into the next-to-last chain, but incrementing
the fullness of the last.  Bug found by Victor Goya.

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.

d9086fc007 Add a new facility to "pin" the memory in an evbuffer chain. 
For overlapped IO (and possibly other stuff) we need to be able to
label an evbuffer_chain as "pinned", meaning that every byte in it
must remain at the same address as it is now until it unpinned. This
differs from being "immutable": it is okay to add data to the end
of a pinned chain, so long as existing data is not moved.

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.

   disclaim some rights is sheer cargo-cultism.

81dd04a726 Add a "flags" field to evbuffer callbacks.

mallocs/frees/tailq-manipulations just to turn a callback on and off.
