afr: Modified book-keeping structures for entrylks
* There are upto 3 entry lockees that may be needed to perform entrylk'ing in posix dir-write operations. * For eg, rmdir ("/a/b") needs to acquire locks on two entities, - entrylk ("/a", "b") - entrylk ("/a/b", null) * Changed existing entrylk/rename/selfheal (entrylk) transactions to use the new book-keeping structures * Fixed few issues in afr_trace_entry_lk{in,out} functions. Tracing is now aware of the new entry lockee structure. Implementation notes: * Changed 'cookie' sent in stack_wind to encode lockee_entity_no and subvol_no. cookie is a non-negative integer such that 0 <= cookie < replica_count, When more than one lock is being acquired across the subvolumes, cookie % replica_count gives the subvol_no cookie / replica_count gives the lockee_entity_no.
