loc_t: add 'gfid' and 'pargfid' fields
these fields are used mainly in case of selfheal path, where 'inode->gfid'||'parent->gfid' is not yet set. These fields in 'loc' will have lower precedence than 'inode->gfid' in client protocol. also contains 'Pranith <pranithk@gluster.com>'s patch to set proper loc->gfid during afr selfheal Signed-off-by: Amar Tumballi <amar@gluster.com> Signed-off-by: Anand Avati <avati@gluster.com> BUG: 2346 (Log message enhancements in GlusterFS - phase 1) URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=2346
