We'd like to prevent local buffer overflows caused by malicious or
broken servers. New xdr_stream style decoders can do that.
For efficiency, we also eventually want to be able to pass xdr_streams
from call_decode() to all XDR decoding functions, rather than building
an xdr_stream in every XDR decoding function in the kernel.
Static helper functions are left without the "inline" directive. This
allows the compiler to choose automatically how to optimize these for
size or speed.

We're interested in taking advantage of the safety benefits of
xdr_streams. These data structures allow more careful checking for
buffer overflow while encoding. More careful type checking is also
introduced in the new functions.
For efficiency, we also eventually want to be able to pass xdr_streams
from call_encode() to all XDR encoding functions, rather than building
an xdr_stream in every XDR encoding function in the kernel. To do
this means all encoders must be ready to handle a passed-in
xdr_stream.
The new encoders follow the modern paradigm for XDR encoders: BUG on
error, and always return a zero status code.
Static helper functions are left without the "inline" directive. This
allows the compiler to choose automatically how to optimize these for
size or speed.

Clean up: Relocate MNT program procedure number definitions to the
only file that uses them. Relocate the version number definitions,
which are shared, to nfs.h. Remove duplicate program number
definitions.

Thanks to Robert Day for pointing out that these two defines are unused.

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!
