Userspace shouldn't have a use for these constants. Nothing here is
used outside fs/nfsd.

At least one of these is actually wrong anyway.

make headers_check fails on linux/nfsd/const.h.
Since linux/sunrpc/msg_prot.h does not seem to export anything interesting
for userspace, this patch moves it in the __KERNEL__ protected section.

The max possible is the maximum RPC payload. The default depends on amount of
total memory.
The value can be set within reason as long as no nfsd threads are currently
running. The value can also be ready, allowing the default to be determined
after nfsd has started.

The limit over UDP remains at 32K. Also, make some of the apparently
arbitrary sizing constants clearer.
The biggest change here involves replacing NFSSVC_MAXBLKSIZE by a function of
the rqstp. This allows it to be different for different protocols (udp/tcp)
and also allows it to depend on the servers declared sv_bufsiz.
Note that we don't actually increase sv_bufsz for nfs yet. That comes next.

This patch changes the 'xdrsize' parameter to svc_create(), to be
NFS4_SVC_XDRSIZE if v4 is defined
else NFS3_SVC_XDRSIZE if v3 is defined
else NFS2_SVC_XDRSIZE (formerly NFSSVC_XDRSIZE)
This always works, since
NFS4_SVC_XDRSIZE >= NFS3_SVC_XDRSIZE >= NFS2_SVC_XDRSIZE.
The value of NFSD_BUFSIZE has also been moved to const.h, since we need
the definition available in nfs4proc.c

Instantiate a new file, include/linux/nfs4.h, which contains
constants and typedef's for the NFSv4 protocol (by analogy with
include/linux/nfs2.h and include/linux/nfs3.h).
Also #include this file in a few places where it will be needed
later.

This increases the max read/write size for nfsd from 8K to 32K.
This requires making NFSv2 return the right number in statfs
requests. NFSv3 already does that.
