Added the following events for the eventing framework:
"EVENT_AFR_QUORUM_MET", --> Sent when quorum is met.
"EVENT_AFR_QUORUM_FAIL" -->Sent when quorum is lost.
"EVENT_AFR_SUBVOL_UP" -->Sent when afr witnesses the first up subvolume.
"EVENT_AFR_SUBVOLS_DOWN"-->Sent when all children of an afr subvol are down.
"EVENT_AFR_SPLIT_BRAIN" -->Sent when self-heal detects split-brain in heal
path (not read/write path).

get_new_dict/dict_destroy is causing confusion where, dict_new/dict_destroy or
get_new_dict/dict_unref are used instead of dict_new/dict_unref.

Problem:
Afr does dict_ref of the xattr_req that comes to it and deletes "gfid-req" key.
Dht uses same dict to send lookup to other subvolumes. So in case of
directories and more than 1 dht subvolumes, second subvolume till the last
subvolume won't get a lookup request with "gfid-req". So gfid reset never
happens on the directories in distributed replicate subvolume for 2nd till last
subvolumes.
Fix:
Make a copy of lookup xattr request.
Also fixed replies_wipe possibly resetting gfid to NULL gfid

When the disk associated with a brick returns EIO during lookup, chances are
that name heal would return an EIO because one of the syncop_XXX() operations
as part of it returned an EIO. This is inherently treated by afr_lookup_selfheal_wrap()
as a split-brain and the lookup is aborted prematurely with EIO even if it
succeeded on the other replica(s).

Instead of including config.h in each file, and have the additional
config.h included from the compiler commandline (-include option).
When a .c file tests for a certain #define, and config.h was not
included, incorrect assumtions were made. With this change, it can not
happen again.

This patch adds support for xdata in both the
request and response path of syncops.
Few calls like lookup already had the support;
have renamed variables in few places to maintain
uniformity.
xdata passed downwards is known as xdata_in
and xdata passed upwards is known as xdata_out.
There is an old patch by Jeff Darcy at
http://review.gluster.org/#/c/8769/3 which does the
same for some selected calls. It also brings in
xdata support at gfapi level.
xdata support at gfapi level would be introduced
in subsequent patches.

glusterfs relies on Linux uuid implementation, which
API is incompatible with most other systems's uuid. As
a result, libglusterfs has to embed contrib/uuid,
which is the Linux implementation, on non Linux systems.
This implementation is incompatible with systtem's
built in, but the symbols have the same names.
Usually this is not a problem because when we link
with -lglusterfs, libc's symbols are trumped. However
there is a problem when a program not linked with
-lglusterfs will dlopen() glusterfs component. In
such a case, libc's uuid implementation is already
loaded in the calling program, and it will be used
instead of libglusterfs's implementation, causing
crashes.
A possible workaround is to use pre-load libglusterfs
in the calling program (using LD_PRELOAD on NetBSD for
instance), but such a mechanism is not portable, nor
is it flexible. A much better approach is to rename
libglusterfs's uuid_* functions to gf_uuid_* to avoid
any possible conflict. This is what this change attempts.

Problem:
When self-heal code doesn't see at least 2 successes on looking up children,
then self-heal can't be done. What is happening now is if all the lookups fail
then the pending changelog is all zeros in xattrs so all the children are
becoming sources and leading to crashes when the code paths further assume that
some data structures are populated properly
Fix:
Don't proceed with self-heals when < 2 children succeed lookups.

Problem:
Counts may give wrong results when the number of bricks is > 2. If the
locks are acquired on one source and sink, but the source accuses even the
down sink then there will be 2 sinks and lock is acquired on 2 bricks so
even when there is a clear source and sink **_finalize_source functions think
the file/directory is in split-brain.
Fix:
Check that all the bricks which are locked are sinks.

Problem:
Allowing lookup with 'gfid-req' will lead to assigning gfid at posix layer.
When two mounts perform lookup in parallel that can lead to both bricks getting
different gfids leading to gfid-mismatch/EIO for the lookup.
Fix:
Perform gfid heal inside lock.
