Export of violin driver 1.0.0-rc6

    - NEW(fcp): Added driver management of LUN IDs.  Now IDs are
      'sticky' so that a LUN that is exported/unexported several times
      will always use the same LUN ID.  Additionally, LUN IDs will not
      be re-used as old LUNs are de-provisioned and new ones are
      provisioned.  Instead, IDs monotonically increase up to 16k and
      then loop around starting at 1.

    - NEW(fcp): Added request/verify code for lun exports/unexports,
      and added synchronization points for certain API functions

    - NEW(iscsi): updated driver with software features previously
      added to fcp driver as of RC5.

    - bug fixes: 24117, 24470, 24476

    - Updated tests and increased code coverage
