porting: Port for FreeBSD rebased from Mike Ma's efforts

- Provides a working Gluster Management Daemon, CLI
- Provides a working GlusterFS server, GlusterNFS server
- Provides a working GlusterFS client
- execinfo port from FreeBSD is moved into ./contrib/libexecinfo
  for ease of portability on NetBSD. (FreeBSD 10 and OSX provide
  execinfo natively)
- More portability cleanups for Darwin, FreeBSD and NetBSD
- Provides a new rc script for FreeBSD
