Use -version-info, not -release.

Browse Source 
Patch from Zack Weinberg.  His description:

This one might be a little more controversial. Libtool's -release and
-version-info options are supposed to be mutually exclusive, but it doesn't
either enforce that or make it sufficiently clear in the manual. Using
both makes the -version-info switch ineffective; you will get sonames like
"libevent-2.0.so.1", "libevent-2.1.so.1", etc., even though version 2.1
will presumably be backward ABI compatible with 2.0.

This patch just takes out the -release switches and bumps the -version-info
value to 2:0:0 so that people looking at the files in /usr/lib will not be
confused (it'll be "libevent.so.2"). This does change the soname, but the
current release is labeled an alpha, and it would be better to stop using
both switches as soon as possible, before someone over at libtool
headquarters decides to enforce the mutual exclusivity here...

Note that libevent_pthreads is not being linked with any versioning
switches I didn't change that because I wasn't sure whether it was
intentional.
