[or-cvs] Make Tor use Niels Provos"s libevent instead of it"s current

[Nick Mathewson]

Update of /home/or/cvsroot/tor
In directory moria.mit.edu:/tmp/cvs-serv9851

Modified Files:
	configure.in 
Log Message:
Make Tor use Niels Provos's libevent instead of it's current
poll-but-sometimes-select mess.  This will let us use faster async cores
(like epoll, kpoll, and /dev/poll), and hopefully work better on Windows
too.

There are some fairly nasty changes to main.c here; this will almost
certainly break something.  But hey, that's what alphas are for.
