* Create a lustre-tests RPM that includes stuff from lustre/tests

-   ptllnd logs a piece of incorrect debug info in kptllnd_peer_handle_hello.

-   should set the_lnet.ln_finalizing before completing messages.

    show state as "up" or "down" - non-routers show "~rtr".

update from b1_6

    - revert default ptltrace_on_timeout to 0 - timeouts can be routine in
      redundant router configurations.
    - merged minor fixes from Cray XT 2.0

  - Error handling

    Ensure all communications complete in finite time.  Ensure errors cause
    clean peer state teardown so that communications can be re-established
    after a peer crash.

    Note that this does NOT handle reconnection to a failed LNET router, which
    is required for routed configurations.

  - Environment tunables

    PTLLND_DEBUG (boolean, dflt 0) is a global switch to enable/disable debug
    features.

    PTLLND_TX_HISTORY (int, dflt debug?1024:0) sets the size of the history
    buffer.

    PTLLND_ABORT_ON_PROTOCOL_MISMATCH (boolean, dflt 1) calls abort on
    connecting to a peer running a different version of the ptllnd protocol.

    PTLLND_ABORT_ON_NAK (boolean, dflt 0) abort when a peer sends a NAK
    (e.g. because it has timed out this node).

    PTLLND_DUMP_ON_NAK (boolean, dflt debug?1:0) dumps peer debug and the
    history on receiving a NAK

    PTLLND_WATCHDOG_INTERVAL (int, dflt 1) sets how often to check some peers
    for timed-out communications while the application blocks for
    communications to complete.

    PTLLND_TIMEOUT (int, dflt 50) is the communications timeout in seconds.

    PTLLND_LONG_WAIT (int, dflt debug?5:PTLLND_TIMEOUT) is a time in seconds
    after which the ptllnd prints a warning if it blocks for longer during
    connection establishment, cleanup after an error or cleanup during shutdown.

Quiet compiler warnings due to printing __u8 instead of char.

Look for dbench client.txt file in /usr/share/dbench also.

Remove extra blank lines.

Run tests in $DIR and not in $MOUNT.

Quiet compile warning when CONFIG_LSF is on (large single file).

Quiet compile warning when CONFIG_LSF is on (large single file).

Quiet warning about use of uninitialized variable.

Fix backticks to be apostrophes in comments.

Change comment so that nobody gets the idea that "#define CDEBUG_ENABLED 0"
is the way to turn this off.

Clarify comment.
