1. Convert cm_volume_t mutex to a rwlock (rw). 

2. Don't hold cm_volume_t lock across RPCs

3. Add CM_VOLUMEFLAG_UPDATING_VL flag to prevent multiple threads
   from performing volume update calls at the same time on the same
   volume set.  

4. Convert the .rw, .ro, and .bk cm_vol_state_t members of cm_volume_t
   to an array of cm_vol_state_t members indexed using the pre-existing
   RWVOL, ROVOL and BACKVOL preprocessor symbols.  This will permit 
   consolidation of code and make it easier to add new volume types
   to the volume set in the future.
