Backport of http://review.gluster.org/11012
Note: http://review.gluster.org/9459 is not backported to 3.6 but the change it
makes to afr_get_heal_info() (i.e. handling ret values) is needed for heal info
to work correctly and tests/basic/afr/client-side-heal.t to pass.
--------------------------
afr-v1 had the following volume set options that are used to enable/ disable
self-heals from happening in AFR xlator when loaded in the client graph:
cluster.metadata-self-heal
cluster.data-self-heal
cluster.entry-self-heal
In afr-v2, these 3 heals can happen from the client if there is an inode
refresh. This patch allows such heals to proceed only if the corresponding
volume set options are set to true.

That way a lookup would be forced on the entry, and its attributes will
always be selected from its read subvol.

Backport of http://review.gluster.org/9480
Problem:
When data-self-heal-algorithm is set to 'full', shd just reads from
source and writes to sink. If source file happened to be sparse (VM
workloads), we end up actually writing 0s to the corresponding regions
of the sink causing it to lose its sparseness.
Fix:
If the source file is sparse, and the data read from source and sink are
both zeros for that range, skip writing that range to the sink.

Problem:
Self-heal pid used to be -1 which was colliding with gsyncd. Gsyncd
was not checked for root-squash authentication. Recently self-heal
pid changed to -6, but root-squash authentication is not disabled
for this.
Fix:
disable root-squash authentication for self-heal

Problems with fuse/server:
Fuse loc touch up sets loc->name even when pargfid
is not known. Server lookup does (pargfid, name) based
lookup when name is set ignoring the gfid. Because of this server
resolver finds that the lookup came on (null-pargfid, name) and
fails the lookup with EINVAL.
Fix:
Don't set loc->name in loc_touchup if the pargfid is not known.
Did the same even for server-resolver
Problem with afr:
Lets say there is a directory hierarchy a/b/c/d on the mount and the
user is cd'ed into the directory. Bring down one of the bricks of replica and
remove all directories/files to simulate disk replacement on that brick. Now
this brick is brought back up. Creates on the cd'ed directory fail with ESTALE.
Basically before sending a create of 'f' inside 'd', fuse sends a lookup to
make sure the file is not present. On one of the bricks 'd' is present and
'f' is not so it sends ENOENT as response. On the new brick 'd' itself is not
present. So it sends ESTALE. In afr ESTALE is considered to be special errno on
witnessing which lookup has to fail. And ESTALE is given more priority than
ENOENT. Due to these reasons lookup fails with ESTALE rather than ENOENT. Since
lookup didn't fail with ENOENT, 'create' can't be issued so the command is
failed with ESTALE.
Solution:
Afr needs to consider ESTALE errno normally and ENOENT needs to
be given more priority so that operations like create can proceed even when
only one of the brick is up and running. Whenever client xlator identifies
that gfid-changed, it sets that information in lookup xdata. Afr uses this
information to fail the lookup with ESTALE so that top xlator can send
fresh lookup.
