The modpost tool could overflow its stack buffer if someone was running
with an insane shell environment. Regardless, it's technically a bug,
so this fixes it to truncate the string instead of seg-faulting.

fixdep: Do not record dependency on the source file itself
changed the format of the *.cmd files without realizing that it is also
used by modpost. Put the path to the source file to the file back, in a
special variable, so that modpost sees all source files when calculating
srcversion for modules.

linked into a module
This fixes a compile time warning which occurs whenever a static library
is linked into a kernel module. MODPOST tries to look for a
".<modulename>.cmd" file to look for its dependencies, but that file
doesn't exist or get generated for static libraries.
This patch prevents modpost from looking for a .cmd file when a module is
linked with a static library

POSIX says limits.h defines PATH_MAX so we should include it (which fixes
compiling on some systems like OS X).

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.

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!
