Pull up following revision(s) (requested by bouyer in ticket #1098):
	lib/libquota/quota_nfs.c: revision 1.5
Some NFS servers return RPC_PROGNOTREGISTERED instead of RPC_PROGVERSMISMATCH
when they don't support EXT_RQUOTAVERS but support RQUOTAVERS, so
retry with RQUOTAVERS for both RPC_PROGNOTREGISTERED and RPC_PROGVERSMISMATCH
return code.
Fix issue against a NetApp server reported by 6bone on current-users

Rebase to HEAD as of a few days ago.

Rebase.

Some more errno remapping: if the NFS server is unreachable because we have
no route to it, assume there are no quotas. While this might sound like
an impossible scenario, it actually happens inside rump tests when we have
a virtual shmif network but are querying quotas for / which happens to
be on NFS (but of course outside of the shmif setup).
This fixes tests/fs/nfs/t_rquotad on diskless clients.

If a rpc for quota values fails with ENOTCONN translate this to ENOENT - we
certainly don't have any quotas if they are disabled on the file server.
This silences warnings from things like "quota -u -v" when NFS mounts
are present and no quotas are in use on the file server.

sync with head

file quota_nfs.c was added on branch yamt-pagecache on 2012-04-17 00:05:32 +0000

Remove redundant break statement.

Add quota_nfs.c and implement quota_get() for nfs, using
code from getnfsquota().

Also implement quota_getmountdevice().
