File preemption.util is renamed and moved to
util.nondecreasing. The new util file can be used
in both the old Prosa and the new Prosa.

Use coqdoc's header feature to make it easier to find key concepts and
improve/tweak a few comments.

... to get support for proofs started by `Next Obligation`.

1) rely on patch to actually patch the Makefile
2) move ineffective 'sed' hackery related to 'make validate'

Re 2), the sed script didn't actually modify the Makefile anyway
(unlear how long it has been ineffective), so let's just remove it.

Add support for compiling only classic Prosa, i.e., the inverse of
--without-classic.

No need to re-generate an unchanging file from scratch.

It's faster to just compile the new stuff. For new developments,
that's sufficient.

This partially addresses #54.

The mathcomp coqdoc documentation is now at:

Tweak our Makefile accordingly.

- Added unfolding lemmas to basic_facts/ideal
- Fixed proofs depending on the previous definition using unfolding lemmas

The changes follow the discussion in Paris.

As discussed in #57.

As discussed at the RT-PROOFS meeting in Paris, proof terms should not
have a name so that we don't actually directly depend on them in
proofs. This patch removes the explicit name of the proof term in the
readiness type class and introduces an equivalent lemma.

If there are breaking changes coming in ssreflect, it would be nice to
know early.
