[2/2] mesos git commit: Re-enable epoll support for libevent.

[bm...@apache.org]

Re-enable epoll support for libevent.

Epoll support was disabled due to some undocumented "issues". Since
the original author is not responsive and a lot of libevent / SSL
issues have been fixed, we can try re-enabling epoll support.

Should this be an issue, epoll can be disabled once again using the
EVENT_NOEPOLL environment variable.
