SUNRPC: Make RPC portmapper use per-transport storage
Move connection and bind state that was maintained in the rpc_clnt
structure to the rpc_xprt structure. This will allow the creation of
a clean API for plugging in different types of bind mechanisms.
This brings improvements such as the elimination of a single spin lock to
control serialization for all in-kernel RPC binding. A set of per-xprt
bitops is used to serialize tasks during RPC binding, just like it now
works for making RPC transport connections.
Test-plan:
Destructive testing (unplugging the network temporarily). Connectathon
with UDP and TCP. NFSv2/3 and NFSv4 mounting should be carefully checked.
Probably need to rig a server where certain services aren't running, or
that returns an error for some typical operation.
