Update version, modernize packaging, accommodate libevent version 2 opaque
evbuffer datatype, port Linux style flock(2) to SVR4, include correct
non BSD and non SVR4 headers in DNS and resolving logic, correctly
include a arc4random(3) implementation for platforms lacking it,
conditionally implement the nonstandard MIN(a,b) macro, and use
parallel make for faster SMP and multicore builds.
