Import libevent 2.0.13.

Libevent is a library for writing fast portable nonblocking IO.

This port omits all the libevent1 compatibility parts so it does
not clash with libevent1 from base.  Applications will link with
-levent_core (-levent_extra) and pkg-config is set up this way.

Verified that none of our libevent1-using ports pick this up by
accident.
