====================
rxrpc: Add bits for kernel services

Here are some patches that add a few things for kernel services to use:

 (1) Allow service upgrade to be requested and allow the resultant actual
     service ID to be obtained.

 (2) Allow the RTT time of a call to be obtained.

 (3) Allow a kernel service to find out if a call is still alive on a
     server between transmitting a request and getting the reply.

 (4) Allow data transmission to ignore signals if transmission progress is
     being made in reasonable time.  This is also usable by userspace by
     passing MSG_WAITALL to sendmsg()[*].

[*] I'm not sure this is the right interface for this or whether a sockopt
    should be used instead.
