[PATCH 03/11 RFC] gitignore: Add/Generalize entries

[Elliott Mitchell <ehem+xen@xxxxxxx>]

"stubdom/*.tar.gz" already existed as an entry.  Given the presence of
tarball ignore rules for tools, generalize the entry to match most
tarballs.  Tarballs should generally be left out of git repositories and
"-f" is appropriate for the very rare exception.

Multiple "config.h" entries had been present.  This is common enough to
add a common entry to cover the pattern everywhere.

Substantial numbers of pkg-config file ignore lines were present.  While
use of pkg-config is being reduced, ignoring such files in general seems
like an appropriate measure.

Python is growing in use, since patterns for underscore files seem likely
to be added, add a safety pattern to ensure Python double-underscore
files are preserved.

I'm pretty sure anything .old is unlikely to need to remain in history.

Question I have is:  Should "_*.[chS]" or "_*" be added as ignore
patterns?

Underscore is frequently used to mark intermediate files used during
build, but not worthy of preservation.  There are a bunch of directories
where "_paths.h" is ignored, and some "_*.[ch]" entries.  Yet should this
be generalized to *all* underscore files?

Preparing for this I've added "!__*__.py" which will override such and
ensure "__init__.py" files are *not* ignored.  I forsee a future where
Python adds another similar filename.
