This patch extends the persistent instrumentation work done by
Aravinda (@avishwa), by introducing a handfull of instrumentation
variables for crawl. These variables are "pulled up" by glusterd
in the event of a geo-replication status cli command and looks
something like below:
"Uptime=00:21:10;FilesSyned=2982;FilesPending=0;BytesPending=0;DeletesPending=0;"
"FilesPending", "BytesPending" and "DeletesPending" are short-lived
variables that are non-zero when a changelog is being processes (ie.
when an active sync in ongoing). After a successfull changelog process
"FilesPending" is summed up into "FilesSynced". The three short-lived
variabled are then reset to zero and the data is persisted
Additionally this patch also reverts some of the changes made for
BZ #986929 (those were not needed).

setting the slave xtime on the slave (after each changelog/xsync)
crawl helps in two things:
* effective recover of master (failover/failback)
* cascading setup - instances when the session from intermediate
master session is stopped, data is put on
the master -> slave sesssion and then the
cascading session is started again.

Now saving the session details in
/var/lib/glusterd/geo-replication/<mastervol>_<slaveip>_<slavevol>
repo to distinguish between two master-slave sessions where the
slavename is same across two different clusters.

A hostname fqdn can be of length 255 according to RFC1123
------------------------->
/usr/include/bits/posix1_lim.h:#define _POSIX_HOST_NAME_MAX 255
<-------------------------
On linux this length is 64
------------------------->
/usr/include/bits/local_lim.h:#define HOST_NAME_MAX 64
<-------------------------
When a given hostname is > 45 (characters) - SSH fails with
-------------------------->
"ControlPath too long for Unix domain socket".
<--------------------------
Indicating that the total length of ControlPath which is
on linux should be 108
------------------------->
/usr/include/linux/un.h:#define UNIX_PATH_MAX 108
<-------------------------
This leads to "faulty" geo-replication status.
This patch brings in a new file called manifest which carries
given a geo-rep session some unique information - with which
a unique `md5` is generated in a 32length digest, this ensures
that we don't exceed UNIX_PATH_MAX limitations instead we use
a conservative approach and still be able to provide a unique
socket path.

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;
New(Ex):
FilesSynced=2;BytesSynced=2507;Uptime=00:26:01;SyncTime=0.69978;
TotalSyncTime=2.890044;TotalFilesSynced=6;TotalBytesSynced=143640;
Persistent details stored in

* also consume changelog for change detection.
* Status fixes
* Use new libgfchangelog done API
* process (and sync) one changelog at a time
