glusterd/cli changes for distributed geo-rep

Commands:
gluster system:: execute gsec_create
gluster volume geo-rep <master> <slave-url> create [push-pem] [force]
gluster volume geo-rep <master> <slave-url> start [force]
gluster volume geo-rep <master> <slave-url> stop [force]
gluster volume geo-rep <master> <slave-url> delete
gluster volume geo-rep <master> <slave-url> config
gluster volume geo-rep <master> <slave-url> status

The geo-replication is distributed. The session will be created, and
gsyncd will be spawned on all relevant nodes, instead of only one
node.

geo-rep: Collecting status detail related data

Added persistent store for saving information about
TotalFilesSynced, TotalSyncTime, TotalBytesSynced

Changes in the status information in socket:
Existing(Ex):
FilesSynced=2;BytesSynced=2507;Uptime=00:26:01;

glusterd: Fixing create force issues while it returned true everytime.

Now geo-rep create force will return true if a node is down, and log an
appropriate message. It will also return true with an appropriate log
message if the slave verification fails.

However it will not return true if the config file is deleted, ot corrupted,
so as not to get the state_file's path. It will also fail if the slave url
is invalid. If the push-pem option is given and
/var/lib/glusterd/geo-replication/common_secret.pem.pub is not present, then
also the create force command will fail.

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.)
