Add gamin, a file and directory monitoring server and API. Gamin can be
used as a drop-in replacement for FAM. Gamin is designed to be more secure
than FAM as itdoes not require RPC, and runs a separate instance for each
user. While it is API and ABI compatible with FAM, it does not [yet]
support all of FAM's features.
This version of gamin comes with an optional (defaults to on) kqueue
backend for FreeBSD. This backend can only be used with UFS file
systems. If you need FAM-like support on non-UFS file systems, you
must build without the kqueue backend.
