Problem: glusterfs(GNFS) is crashing at the time of handling
Pollerr event in rpcsvc_drc_client_unref.GNFS is crashed
because ref was 0 at the time of unref and ref was taken
while Pollin event successfully handled.
Solution: Convert drc_client ref to atomic ref to avoid the crash

There are many include statements that are not needed.
A previous more ambitious attempt failed because of *BSD plafrom
(see https://review.gluster.org/#/c/glusterfs/+/21929/ )
Now trying a more conservative reduction.
It does not solve all circular deps that we have, but it
does reduce some of them. There is just too much to handle
reasonably (dht-common.h includes dht-lock.h which includes
dht-common.h ...), but it does reduce the overall number of lines
of include we need to look at in the future to understand and fix
the mess later one.

Mostly, unlock before logging.
In some cases, moved different code that was not needed
to be under lock (for example, taking time, or malloc'ing)
to be executed before taking the lock.
Note: logging might be slightly less accurate in order, since it may
not be done now under the lock, so order of logs is racy. I think
it's a reasonable compromise.
Compile-tested only!

libglusterfs devel package headers are referenced in code using
include semantics for a program, this while it works can be better
especially when dealing with out of tree xlator builds or in
general out of tree devel package usage.
Towards this, the following changes are done,
- moved all devel headers under a glusterfs directory
- Included these headers using system header notation <> in all
code outside of libglusterfs
- Included these headers using own program notation "" within
libglusterfs
This change although big, is just moving around the headers and
making it correct when including these headers from other sources.
This helps us correctly include libglusterfs includes without
namespace conflicts.

Currently, there are possibilities in few places, where a user-controlled
(like filename, program parameter etc) string can be passed as 'fmt' for
printf(), which can lead to segfault, if the user's string contains '%s',
'%d' in it.
While fixing it, makes sense to make the explicit check for such issues
across the codebase, by making the format call properly.

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.

* A wrong memory allocator was used to (de)allocate nodes (not data in
them) of rb tree. This patch uses default allocator, since that suits
our purpose.
* Fix reference counting of client, though hitting the codepath
containing this bug is highly unlikely.

DRC in NFS causes memory bloat and there are known memory corruptions.
It would be good to disable drc by default till the feature is stable.

After the drc cache get full, message "DRC failed to detect duplicates" keep
printed in the log.
The root cause is drc_compare_reqs use the wrong compare type. This function
should use type drc_cache_op_t as its input type. Since all rbtree related code
(except function rpcsvc_drc_lookup) in drc cache pass drc_cache_op_t as compare
type. Only rpcsvc_drc_lookup use type rpcsvc_request_t. It has been modified
too.

1. The routine rpcsvc_drc_init() is only used while initialization of
NFS xlator. It should just check for nfs.drc option and init DRC feature
accordingly. If it's set to OFF, then rpcsvc_drc_init() allocates memory
for svc.drc and set ret value to 0 and goes to out: block where drc is
leaked.
2. rpcsvc_drc_init() should just allocate svc.drc and init it. Here
svc.drc can never be valid.
3. If svc.drc gets init'd here, no point of checking for drc type here.

1) Fix the typo in NFS default ACL
The typo was introduced as part of the Fix to BZ 1009210 i.e.
http://review.gluster.org/5980. The user ACL xattr structure
was passed to default ACL xattr.
2) Clean up NFS code to avoid unnecessary SEGV in
rpcsvc_drc_reconfigure() which was not validating the
svc->drc. Add a routine rpcsvc_drc_deinit() to handle
the clean up of DRC specific data structures. For init(),
use rpcsvc_drc_init().
3) nfs_init_state() was returning wrong value even if the
registration with portmapper failed, causing the NFS
server process to hang around. As a result it used to
get SEGV during rpcsvc_drc_reconfigure().
4) Clean up memfactor usage across nfs.c nfs3.c.

Implement reconfigure() for NFS xlator so that volume set/reset wont
restart the NFS server process. But few options can not be reconfigured
dynamically e.g. nfs.mem-factor, nfs.port etc which needs NFS to be
restarted.

Duplicate request cache provides a mechanism for detecting
duplicate rpc requests from clients. DRC caches replies
and on duplicate requests, sends the cached reply instead of
re-processing the request.
