libglusterfs/client_t client_t implementation, phase 1
Implementation of client_t
The feature page for client_t is at
http://www.gluster.org/community/documentation/index.php/Planning34/client_t
In addition to adding libglusterfs/client_t.[ch] it also extracts/moves
the locktable functionality from xlators/protocol/server to libglusterfs,
where it is used; thus it may now be shared by other xlators too.
This patch is large as it is. Hooking up the state dump is left to do
in phase 2 of this patch set.
(N.B. this change/patch-set supercedes previous change 3689, which was
corrupted during a rebase. That change will be abandoned.)
BUG: 849630
