  2. reduce sync requests to owner server 

    This adds batching of client extent sync requests at
each server to try to limit the number of RPCs to the
owner to one-per-server, rather than one-per-client.
It also avoids doing metaget RPCs for the mountpoint.

Also:
* use ABT_rwlock instead of pthread_rwlock_t
* add comparison functions for int/float types to common
* fix misused return code
* fix free() of uninitialized margo bulk buf pointers
* remove last vestiges of MPI in server
* remove last vestiges of MDHIM in server
