libtool: Update patchset to match those submitted upstream

I went through and cleaned up the headers/descriptions on several of the
libtool patchset and submitted (or resubmitted in some cases) them
upstream. This patch updates/renames them to match what I did.

I did fix some whitespace issues in some of the patches and also merged
one case where we had a patch of already patched code.

This makes it clear what was submitted and makes resubmission easier if
ever needed too.
