Move all remaining tests except for:

make(1):	Does not work like the other tests.  Its Makefile is
			self-testing.
	m4(1):		It uses complex voodo to test GNU m4(1) features.

To the new framework.  I had worried about passing the binary data that
uudecode(1)'s test passes to diff(1) might give a user something nasty,
but this is unlikely to happen as even with an unmodified old nasty
diff(1) which doesn't recognise many binary files, these binary files
are recognised.  Using $DIFF instead of `diff' in the library and making
it possible to override this with `cmp -s' might be nice some day, but
as of this second, there's no immediate need.
