The second installment to libify diff brothers. The pathname
arguments are checked more strictly than before because we now
use the revision.c::setup_revisions() infrastructure.

This is the first installment to libify diff brothers.
The updated diff-files uses revision.c::setup_revisions()
infrastructure to parse its command line arguments, which means
the pathname arguments are checked more strictly than before.
The tests are adjusted to separate possibly missing paths from
the rest of arguments with double-dashes, to show the kosher
way.
As Linus pointed out, renaming diff.c to diff-lib.c was simply
stupid, so I am renaming it back. The new diff-lib.c is to
contain pieces extracted from diff brothers.

When a verbatim rename or copy is detected, we did not show
anything on the "diff --stat" for the filepair. This makes it
to show the rename information.
