Added support for multiple event loop / IO threads for libev. The current approach to I/O in libprocess, with a single thread performing all of the the I/O polling and I/O syscalls, cannot keep up with the I/O load on massive scale mesos clusters (which use libev rather than libevent). This adds support via a LIBPROCESS_LIBEV_NUM_IO_THREADS env variable for configuring the number of threads running libev event loops, which allows users to spread the IO load across multiple threads.
