3c7d6fcaff Fix race caused by event_active 
There is a race between manual event_active and natural event activation. If both happen at the same time on the same FD, they would both be protected by the same event base lock except for 1 LoC where the fields of struct event are read without any kind of lock. This commit does those reads into local variables inside the lock and then invokes the callback with those local arguments outside the lock. In 2.0-stable, none of this is inside the lock; in HEAD, only the callback is read inside the lock. This gets the callback and all 3 arguments inside the lock before calling it outside the lock.

b56611d705 Add -Qunused-arguments for clang on macos 
The clang compiler provided with macosx emits warnings like:

  CC       bufferevent.lo
clang: warning: argument unused during compilation: '-I .'
clang: warning: argument unused during compilation: '-I ./compat'
clang: warning: argument unused during compilation: '-I ./include'
clang: warning: argument unused during compilation: '-I ./include'

for each file being compiled. This generates a lot of noise during
compilation making it hard to see "real" errors. This patch mute
those warnings.

5eb178855a Avoid racy bufferevent activation 
The evhttp_send_reply method invokes evhttp_write_buffer with a
callback that may release the underlying request object and
bufferevent upon completion. This cleanup callback is invoked by the
underlying bufferevent's write callback. Improperly enabling write
events before referencing the bufferevent could lead to use after free
and memory corruption.

e826f19e05 Use windows vsnprintf fixup logic on all windows environments

conformant return value.  But it appears that some mingw
environments don't do that.

9ab2b3f749 Fix missing AC_PROG_SED on older Autoconfs 
For pre-2.59b Autoconfs, AC_PROG_SED is not available [1]; on such
systems, avoid calling AC_PROG_SED, while providing a sensible SED.

This aids backporting to Autoconf 2.59.
