Add a generic (unoptimized) implementation of checksum.c in pure C
for use by all architectures that cannot be bother with implementing
their own version.

This changes the function prototypes in the checksum code
to have the usual prototypes, typically by turning int
arguments into __wsum.
Also change csum_partial_copy_from_user() to operate
on the right address space and export ip_fast_csum,
which is used in modular networking code.
The new version is now sparse-clean including endianess
checks.

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!
