modpost is now called with .o files that are not modules.
So do not warn if there is no corresponding .mod
file listing .o files (in .tmp_versions/).

A combination of calling modpost with option -a and MODVERDIR undefined
caused segmentation fault. So provide a default value and accept the
error messages it generates instead.

modpost.c provides warn() and fatal() - so use them all over the place.

This time I did not break anything... and they shut up gcc4 ;)

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!
