Summary:
- This diff changes all locations in the code to prefer inet6 family
  instead of inet.  This will allow change GlusterFS to operate
  via IPv6 instead of IPv4 for all internal operations while still
  being able to serve (FUSE or NFS) clients via IPv4.
- The changes apply to NFS as well.
- This diff ports D1892990, D1897341 & D1896522 to the 3.8 branch.

Test Plan: Prove tests!

Problem: "gluster volume heal info [healed] [heal-failed]" command
          output on terminal is not appropriate in case of down any volume.

Solution: To make message more appropriate change the condition
          in function "gd_syncop_mgmt_brick_op".

Test : To verify the fix followed below procedure
       1) Create 2*3 distribute replicate volume
       2) set self-heal daemon off
       3) kill two bricks (3, 6)
       4) create some file on mount point
       5) bring brick 3,6 up
       6) kill other two brick (2 and 4)
       7) make self heal daemon on
       8) run "gluster v heal <vol-name>"

Note: After apply the patch options (healed | heal-failed) will deprecate
      from command line.

Issue : At condition "ret", the value of "ret" must be equal to 0.
The condition "ret" cannot be true since the value is always 0.
Hence, the execution cannot reach the statement "goto out"

Solution : The never-true if-condition and its body has to be removed

Fix : The always false if-condition and the dead code under this
if-condition was removed.

The headerfile globals.h is recursively adding itself.
( globals.h -> xlator.h -> stack.h -> globals.h).
We are finding the source files which are including the header
file globals.h and removing the inclusion line.

I used git grep -l stack.h | xargs git grep globals.h --
to find out the files and removed the header file from all files
except libglusterfs/src/xlator.h and libglusterfs/src/Makefile.am

When I try to remove header file from libglusterfs/src/xlator.h
I'm getting some errors. In libglusterfs/src/Makefile.am it is
required for building RPMs.
