m68k: implement __clear_user(), which is needed by fs/signalfd.c
Since we always let the MMU do all checking, clear_user() and __clear_user()
are identical. The old clear_user() is renamed to __clear_user() for
consistency.

This uninlines a few large functions in uaccess.h and cleans up the rest.
It includes a (hopefully temporary) workaround for the broken typeof of
gcc-4.1.

Use the builtin functions for memset/memclr/memcpy, special optimizations for
page operations have dedicated functions now. Uninline memmove/memchr and
move all functions into a single file and clean it up a little.

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!
