Problem:
Geo-rep fails to sync rename of symlink if it's
renamed multiple times if creation and rename
happened successively
Worker crash at slave:
Traceback (most recent call last):
File "/usr/libexec/glusterfs/python/syncdaemon/repce.py", in worker
res = getattr(self.obj, rmeth)(*in_data[2:])
File "/usr/libexec/glusterfs/python/syncdaemon/resource.py", in entry_ops
[ESTALE, EINVAL, EBUSY])
File "/usr/libexec/glusterfs/python/syncdaemon/syncdutils.py", in errno_wrap

cls.raise_oserr()
File "/usr/libexec/glusterfs/python/syncdaemon/libcxattr.py", in raise_oserr
raise OSError(errn, os.strerror(errn))
OSError: [Errno 12] Cannot allocate memory
Geo-rep Behaviour:
1. SYMLINK doesn't record target path in changelog.
So while syncing SYMLINK, readlink is done on
master to get target path.
2. Geo-rep will create destination if source is not
present while syncing RENAME. Hence while syncing
RENAME of SYMLINK, target path is collected from
destination.
Cause:
If symlink is created and renamed multiple times, creation of
symlink is ignored, as it's no longer present on master at
that path. While symlink is renamed multiple times at master,
when syncing first RENAME of SYMLINK, both source and destination
is not present, hence target path is not known. In this case,
while creating destination directly at slave, regular file
attributes were encoded into blob instead of symlink,
causing failure in gfid-access translator while decoding
blob.
Solution:
While syncing of RENAME of SYMLINK, when target is not known
and when src and destination is not present on the master,
don't create destination. Ignore the rename. It's ok to ignore.
If it's unliked, it's fine. If it's renamed to something else,
it will be synced then.

ssh-port validation is mentioned as `validation=int` in template
`gsyncd.conf`, but not handled this during geo-rep config set.

Added a command to set "features.read-only" option
to a default value "on" for slave volume.
Changes are made in:
$SRC//extras/hook-scripts/S56glusterd-geo-rep-create-post.sh
for root geo-rep and
$SRC/geo-replication/src/set_geo_rep_pem_keys.sh
for non-root geo-rep.

1. '--ignore-mising-args' option for rsync is not
being used even though the rsync version is
greater than 3.1.0. Fixed the same.
2. '--existing' option for rsync is also not being
used. Fixed the same.
3. geo-rep config fails to set rsync-options as the
value contains '--'. Interestingly, python argsparse
treats the value with '--' (e.g., --ignore-missing-args)
as option. But when passed with something like
--value=--ignore-missing-args, it succeeds. Fixed the
same.

Always use ssh and scp with "-oPasswordAuthentication=no"
and "-oStrictHostKeyChecking=no" options. It might hang
the post script otherwise leading geo-rep setup failure
Also increased geo-rep timeout. Occasionally, it's taking
more time to reach Active/Passive status. Especially, the
first start after create.

libargp or argp-standalone is available on all commonly used
distributions. There is no need to bundle an unmaintained version of
argp-standalone in this repository anymore.
FreeBSD places the argp.h file in /usr/local/include when
argp-standalone is installed. This path is not added to CPPFLAGS by
default, so thats done in configure.ac as well.

since some time, geo-rep tests were in the border of 180-190 seconds to
complete. As actual test timeout is 200 seconds by default, giving
these tests some buffer time to complete properly.

1. rsnapshot creates a I/O pattern which involves
create, rename, symlink, hardlink in specific
order.
2. Hardlink rename on master with source unlinked use case

Added a test case of symlink rename and directory
creation with the name same as original symlink
file. Also fixed few other issues in geo-rep.rc

These tests are prone to issues at the moment that need further
debugging and fixing.

as we run regression with a 'sort' function, geo-rep thus becomes last test to run.
instead, make sure it is the first test by changing the name of directory, and thus
any setup failures would be noticed much earlier.
