Since structures with `flexible array members' are an incomplete datatype ANSI
C99 forbids creating instances of them. This patch removes such an instance
from `diff-lib.c' and replaces it with a pointer to a `struct
combine_diff_path'. Since all neccessary memory is allocated at once the number
of calls to `xmalloc' is not increased.

"diff-index -m" does not mean "do not ignore merges", but means
"pretend missing files match the index".
The previous round tried to address this, but failed because
setup_revisions() ate "-m" flag before the caller had a chance
to intervene.

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.
