v4:
1) creation and destruction on rpcbind clients now depends on service program
versions "vs_hidden" flag.

This patch is required for further RPC layer virtualization, because rpcbind
clients have to be per network namespace.
To achive this, we have to untie network namespace from rpcbind clients sockets.
The idea of this patch set is to make rpcbind clients non-static. I.e. rpcbind
clients will be created during first RPC service creation, and destroyed when
last RPC service is stopped.
With this patch set rpcbind clients can be virtualized easely.


The following series consists of:

Patchset looks good to me. The only remaining thing I think is to set
vs_hidden on nfs4_callback_version4, but that patch is orthogonal to
this set.
