Merge: 3341b1e 09d7195

    Merge branch 'fix-vmeBus_Mutex' into release-coda3.1

commit 09d71952f682e1e4b57b2831d82ab7e7f2f56b18
Author: Bryan Moffit <moffit at jlab.org>
Date:   Wed Mar 26 16:39:30 2014 -0400

    jvme.{c,h}
     - vmeBusMutexInit: Add some stdout showing initialization
     - vmeBusLock, vmeBusTryLock: better handling of EOWNERDEAD
       and better stdout error messages
     - vmeBusLock, vmeBusTryLock, vmeBusUnlock return OK, ERROR
       or the error reported by the associated pthread_mutex_* call
     - New routine: vmeBusTimedLock(..).  Does the same as
       pthread_mutex_timedlock.  Takes seconds as an argument
     - Better mutex recovery in
       vmeCheckMutexHealth: Takes seconds for timedlock part.
       If process holding lock dies, will reinitialize the mutex.
       - Should also handle issues from when the "robust"ness of the
         mutex is fooled.  However, assumes you aren't using the lock
         for more than the time prescribed in the argument (timedlock)

    crashLock.c
     - Example of program that crashes after locking mutex, but
       does mutex does not retain it's "robust"ness.

commit 8ee3a8d44a8b933fb8541cae7bee9db68577aa09
Author: Bryan Moffit <moffit at jlab.org>
Date:   Wed Mar 26 11:11:48 2014 -0400

    jvme.c
     - vmeBusMutexInit: Move mutex attribute destroy to
       vmeBusKillLockShm
     - vmeBusKillLockShm: add option to destroy mutex

commit 1d13ada39d6adff3755120850981d0e191767b60
Author: Bryan Moffit <moffit at jlab.org>

    Add program that crashes when the vmeBus mutex is locked

commit 4cf14b68b307375e2fc14812cb7e7a15b7a7181e
Author: Bryan Moffit <moffit at jlab.org>
Date:   Tue Mar 25 13:22:34 2014 -0400

    jvme.{c,h}
     - Add mutex attribute into the shared memory structure
     - Move the mutex initialization into it's own static routine,
       so that it may be repeated in the future
     - Clean up the messages printed to standard out
     - Add routine to check the health of the mutex

commit 3341b1e849d759cb5988422e3b5a390a0d846fd1

    dmaPList.c
     - Add 2KB onto requested size of individual buffers to allow for 2KB
    flush size from DMA Completion from BERR/2eTERM
    
    jlabgefDMA.c
     - When calculating size of buffer remaining, account fo 2KB flush
    size from DMA Completion from BERR/2eTERM.
     - Add extra global variable to keep track of BERR status from the
    most recent DMA transfer. This variable is set within
    jlabgefDMASend(...)
