Replace references to system_utsname to the per-process uts namespace
where appropriate. This includes things like uname.
Changes: Per Eric Biederman's comments, use the per-process uts namespace
for ELF_PLATFORM, sunrpc, and parts of net/ipv4/ipconfig.c

Replace xprt_create_proto/rpc_create_client with new rpc_create()
interface in the Network Lock Manager.
Note that the semantics of NLM transports is now "hard" instead of "soft"
to provide a better guarantee that lock requests will get to the server.
Test plan:
Repeated runs of Connectathon locking suite. Check network trace to ensure
NLM requests are working correctly.

Clean-up: replace rpc_call() helper with direct call to rpc_call_sync.
This makes NFSv2 and NFSv3 synchronous calls more computationally
efficient, and reduces stack consumption in functions that used to
invoke rpc_call more than once.
Test plan:
Compile kernel with CONFIG_NFS enabled. Connectathon on NFS version 2,
version 3, and version 4 mount points.

Add fields to the rpc_procinfo struct that allow the display of a
human-readable name for each procedure in the rpc_iostats output.
Also fix it so that the NFSv4 stats are broken up correctly by
sub-procedure number. NFSv4 uses only two real RPC procedures:
NULL, and COMPOUND.
Test plan:
Mount with NFSv2, NFSv3, and NFSv4, and do "cat /proc/self/mountstats".

Clean up: Every ULP that uses the in-kernel RPC client, except the NLM
client, sets cl_chatty. There's no reason why NLM shouldn't set it, so
just get rid of cl_chatty and always be verbose.

Compile with CONFIG_NFS enabled.

Ensure that we don't create an RPC client without checking that the server
does indeed support the RPC program + version that we are trying to set up.
This enables us to immediately return an error to "mount" if it turns out
that the server is only supporting NFSv2, when we requested NFSv3 or NFSv4.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
