Add 3436 file system regression tests in 184 files.

Almost all regression tests are based on very flexible fstest tool.
They verify correctness (POSIX conformance) of almost all file
system-related system calls.

The motivation behind this work is my ZFS port and POSIX, who doesn't
provide free test suites.

Runs on:	FreeBSD/UFS, FreeBSD/ZFS, Solaris/UFS, Solaris/ZFS

To try it out:

	# cd fstest
	# make
	# find tests/* -type d | xargs prove
