If anything changes anywhere in the graph, all xlators know that
something has changed. Previously dht and afr would mask certain
events from propagating up. Now they forward GF_EVENT_CHILD_MODIFIED
event in those situations

This fixes a race in dht_getxattr() where the xattr dictionary
returned by one of the subvolumes can get free'd before STACK_UNWIND,
leading to applications seeing junk values.

Fuse cant send aux gids. So access-control checks treat
non-primary-group membership of user as "other". So skip
access-control checks if the call is from fuse. We added a hack to
treat all calls with pid set to 1 as calls from nfs. So for calls with pid
not 1 we skip the access-control checks on all fops.

BUG: 971 (dynamic volume management)

Revert "nfs3: Unref & unbind dir fd with inode lock on EOF"
This reverts commit 4e6fb304ce41acbaf7c9ba67c06bf443e65082e8.
The above commit (which unbinds fds at EOF) does not fix the original
bug (1619) because a readdir from a second app could have already
started before the readdir_cbk of the first app's readdir reaches
NFS code. Hence the race still exists.
Performing extra unrefs when EOF is received is not a reliable way
of detecting that a client has performed a closedir (and to close
the fd ourselves). Neither is interpreting a 0 cookies a new opendir.
Clients can always use telldir/seekdir and hit EOFs twice.
Due to the way NFS3 protocol is designed, it is just not possible
for the server to reliably detect opendirs/closedirs performed by
the client and map the corresponding readdirs to the same dir fd
on the server side.
The only reliable way of fixing this is to perform opendir/closedir
at the cost of performance. Any optimization towards keeping dir fds
open attempting to map them with application's opendir/closedir will
either result in fd leaks or extra fd unrefs.

Generating a volfile occurs in two steps:
- Build a graph (ie, glusterfs_graph_t instance) by graph manipulation
primitives
- Write out the graph to a file by the the graph printing API.
Graph builder routines can optionally make use of a "modifier dict",
which can contain overrides wrt. volume options. This can be used
for a "dry-run" graph generation.
