Problem:
Whenever gluster volume heal vol full command is executed, the entries
stored in the circual buffer for sh->healed are added in the dictionary
in the _crawl_post_sh_action function irrespective of whether actual self heal
(due to non-zero values in chage log) takes place or not.
Fix:
Value of key (actual-sh-done) will be set to 1 whenever self heal takes place
due to non-zero change log values and if for some FOP self heal daemon finds
that no self heal required after examining the pending matrix, the value will
be 0.

Problem:
Entry/Data self-heal is orthogonal to meta-data self-heal.
meta-data split-brain should not affect entry/data self-heal.
Fix:
Prevented aborting rest of the self-heals when metadata split-brain
happens.
Tests:
1) Simulated meta-data split-brain then checked data-self-heal
succeed on regular file, entry-self-heal succeed on dir.
2) Reset meta-data change-log on one of the subvols and checked
that meta-data self-heal also completes.
3) Executed self-heal sanity script.

- (Excessive) Logging has been very useful as 'bread-crumbs' in
many a root-cause analyses. This patch aims at avoiding logging when
the information could be reconstructed using the xattrs, statedump,
and/or "volume heal" CLI commands.

RCA
The bug is observed because the decision to mark
a file in split-brain is taken outside appropriate locks.
Lookup gathers xattrs outside any lock. The xattrs being
in split-brain in lookup should only be taken as a hint.
Appropriate inodelks should be taken before confirming
a split-brain. Self-heal confirms this at the moment.
If data/metadata self-heal is turned off, inspecting of
xattrs could not be performed so split-brain behavior
does not work correctly if the self-heal options are turned off.
Fix
Self-heals are launched to inspect xattrs even when the
data/metadata self-heal options are turned off. The decision
to heal data/metadata after the xattrs are inspected is based
on whether the options are turned on/off. So decision to set/reset
split-brain flag is taken inside appropriate locks.

RCA:
Data self-heal for non regular files open the files
and then proceeds using that fd. This approach
does not work for symlinks because open on symlink opens
the file resolved by it.
Fix:
If the file is not a regular file then perform self-heal using
loc. It needs to get 'big' lock and then perform lookup to get
changelog then erase data part of chagelog, then unlock.

The xattrop order in pre/post op on all the subvols
is client-0, client-1... client-n where n is (replica-count - 1).
This order can lead to invalid split-brains if the brick
dies in the middle of xattrops.
Example: transaction completed pre-op, so on all the subvolumes
xattrs have '1' changelog. Now post-op is sent to both the subvols.
On subvol-0 change-log of client-0 is decremented to 0, before
decrementing change-log of client-1 to 0 the brick dies.
This change-log status on subvol-0 gives the meaning that a
change is done on subvol-0 successfully but on subvol-1 it failed.
Which is not what happened.
Changes done when the subvol-0 was down will lead to pending
change-log on subvol-1 for subvol-0. Which is correct.
When the subvol-0 is brought back up, the change-log will be in
split-brain state even when it is not a legitimate split-brain.
If the brick dies in the middle of xattrops it should remain fool.
Pre-op should perform xattrop of the local change-log first and
post-op should perform xattrop of the local change-log last.
In case of optimistic changelogs txn_changelog should be done
last on local if it succeeds, first if it fails.

Fixes self-heal of special files like device files, fifo files, socket files
etc. Does it by doing the following:
* Prevent setting of pending data xattr on a special file during entry self-heal
when a new fils is created.
* Allow data self-heal to be started on all file types other than directories.
During data self-heal, for special files just erase pending xattrs, if those
xattrs were set by previous releases of glusterfs.

By default, lookup triggers data self-heal but that is not the preferred way
of operating replicated volumes. We would like the data self heals to be
triggered in open instead.
Number of back-ground self-heals allowed is 16 and lookups block until
self-heal is completed. We want to prevent blocking in fops. We can not make
lookups independent of self-heal frames because when there are gfid conflicts
the decision of which file is correct is determined in self-heal phase.
So in afr, lookup self-heal is going to guarantee name space consistency
and open/fd fops will take responsibility for data consistency, these
are non blocking. The user needs to set the option cluster.data-self-heal
"open" for this behavior.

This fixes ~200 such warnings, but leaves three categories untouched.
(1) Rpcgen code.
(2) Macros which set variables in the outer (calling function) scope.
(3) Variables which are set via function calls which may have side effects.

If write/truncate fails we should remove the child that failed the fop
from the fresh children. The previous code assumes that the children
that succeeded the fop are fresh children, which is wrong. Fixed that
in this patch.

afr_sh_mark_sources now returns:
-1 if two wise subvols conflict (split-brain)
0 if all subvols are innocent (no self-heal needed)
>0 if sources found
Also, changes to callers of afr_sh_mark_sources to handle return
value properly.
