protocol/server: support server.all-squash

We still use gnfs on our side, so do a little work to support
server.all-squash. Just like server.root-squash, it's also a
volume wide option. Also see bz#1285126

$ gluster volume set <VOLNAME> server.all-squash on

Note: If you enable server.root-squash and server.all-squash
at the same time, only server.all-squash works. Please refer
to following table

+---------------+-----------------+---------------------------+
|               |all_squash       | no_all_squash             |
+-------------------------------------------------------------+
|               |                 |anonuid/anongid for root   |
|root_squash    |anonuid/anongid  |useruid/usergid for no-root|
+-------------------------------------------------------------+
|no_root_squash |anonuid/anongid  |useruid/usergid            |
+-------------------------------------------------------------+
