r272057:

  Import pjdfstest from ^/vendor/pjdfstest/abf03c3a47745d4521b0e4aa141317553ca48f91

  - Remove tools/regression/pjdfstest
  - Add upgrade directions for contrib/pjdfstest
  - Add a note to UPDATING for the move (the reachover Makefiles are coming
    soon)

  Functional differences:
  - ftruncate testcases are added from upstream (github)

  Non-functional differences:
  - The copyright for the project has been updated to 2012
  - pjd's contact information has been updated

  Discussed with: -testing, jmmv, pjd

r272083:

  Expect ELOOP on Darwin/Linux with "O_NOFOLLOW was specified and the target is a
  symbolic link" case. Assume EMLINK on the rest of the OSes (FreeBSD, Solaris,
  etc)

r272084:

  Fix the executed testplan count

  Sponsored by: EMC / Isilon Storage Division

r272087:

  Increase the memory disk size in the following testcases to avoid mount
  failures, which would cause cascade failures in the rest of the test
  run:

  link/15.t, open/19.t, mkdir/11.t, mkfifo/11.t, symlink/11.t

  Fail quickly in all of the testcases if mdconfig, mount, umount, etc
  fails to avoid issues similar to this in the future

r274016:

  Integrate pjdfstest test suite execution into kyua

  pjdfstest execution is opt-in and must be done as root due to some of the
  assumptions made by the test suite and lack of error checking in the non-root
  case

  A description of how to execute pjdfstest with kyua is provided in
  share/pjdfstest/README

MFC r274364:

  Add baud rate support to telnet(1)

  Revert WiP to contrib/tzcode accidentally committed with r274364
MFC r275170:

  Convert sbin/mdconfig/tests from prove format tests to ATF format tests

  As a side effect...
  1. The tests now checks for the root user before continuing with kyua, which is
     more visible than the test being skipped with the TAP protocol
  2. The tests work with devices that aren't /dev/md0 by caching the device
     attached during the test to a file, and later use the cached information to
     detach the device in the cleanup routine
  3. The tests no longer require perl to run
