core/setxattr: prevent users from setting glusterfs xattrs
* Each xlator prevents the user from setting glusterfs-internal
xattrs like trusted.gfid by handling it in respective setxattr
functions. The speacial case of trusted.gfid is handled in
fuse (Not in posix because posix_setxattr is used to set gfid).
* For xlators which did not define setxattr and/or fsetxattr,
the functions have been implemented with appropriate checks.
xlator | fops-added

1. afr | fsetxattr
2. stripe | setxatrr and fsetxattr
3. quota | setxattr and fsetxattr
