afr, index: Clean up stale directory and file indices in granular entry sh

2016-07-15T13:43:13+00:00

	Backport of: http://review.gluster.org/14832

Specifically when a directory tree is removed (rm -rf)
while a brick is down, both the directory index and the
name indices of the files and subdirs under it will remain.
Self-heal will need to pick up these and remove them.

Towards this, afr sh will now also crawl indices/entry-changes
and call an rmdir on the dir if the directory index is stale.

On the brick side, rmdir fop has been implemented for index xl,
which would delete the directory index and its contents if present
in a synctask.

features/index: Delete parent dir indices when heal on it is complete

2016-07-15T07:03:13+00:00

        Backport of: http://review.gluster.org/#/c/14781

In this patch, the state information about whether a directory
gfid index is present or not is stored in the inode ctx with
values IN and NOTIN. This saves index xl the need to perform
stat() everytime an index_entry_create() is called.

When a brick is restarted these in-memory inode ctx records will
be gone. So when granular entry heal happens after a brick is restarted,
and a post-op is done on the parent, if the state gotten from inode ctx
is UNKNOWN, then index xl does a stat to initialize the state as IN or
NOTIN. Note that this is a one-time operation for the lifetime of the
brick. Such a change also helps avoid calling index_del() in
xattrop_index_action() periodically even when granular self-heal is
disabled or when the volume type is disperse.

Most of the tests borrowed from Anuradha's original replace-brick
and add-brick tests under tests/basic/afr/.
