Pull down pjdfstest 0.1

The summary of changes is as follows..

Generic changes::
- Added configure support [2].
- Check for lchmod filesystem support with create_file(..); for
  testcases that require lchmod, skip the testcase -- otherwise
  use chmod directly [1].
- Added Travis CI integration [2].
- Added utimensat testcases [1].

Linux support::
- Fixed Linux support to pass on later supported versions of
  Fedora/Ubuntu [2].
- Conditionally enable posix_fallocate(2) support [2].

OSX support::
- Fixed compilation on OSX [2].
- Added partial OSX support (the test run isn't fully green yet)
  [2].

-Few notes on how to use pjdfstest in short steps:
-
-	# cd pjdfstest
-	# vi tests/conf
-	Change 'fs' to file system type you want to test (UFS or ZFS).
-	# vi Makefile
-	You need to manually tweak few things by editing CFLAGS lines
-	at the top of the file.
-	# make
-	It will compile pjdfstest utility which is used by regression tests.
-	# cd /path/to/file/system/you/want/to/test/
-	# prove -r /path/to/pjdfstest/tests
-
-That's all. Enjoy.
-
-Currently supported operating systems: FreeBSD, Solaris.
-Currently supported file system types: UFS, ZFS.
