libgfapi: Add new api for supporting mandatory-locks
The current API for byte-range locks [glfs_posix_lock()] doesn't
allow applications to specify whether it is advisory or mandatory
type locks. This particular change is to introduce an extended
byte-range lock API with an additional argument for including
the byte-range lock mode to be one among advisory(default) or
mandatory. Patch also includes a gfapi test case which make use
of this new api to acquire mandatory locks.
