This commit connects the two ways with which one can specify that a
schedule is an EDF schedule in PROSA: the `EDF_schedule` predicate
and the `respects_policy_at_preemption_point` with the EDF priority
policy predicate. We connect these two definitions by showing that
they're equivalent. We then restate the optimality proof of EDF
schedules using the proven equivalence.

...and some supporting theory. This will be needed to handle arrival curves extrapolated from a finite prefix.

The names for job's and task's run-to-completion
threshold functions are so long that it often gets
in the way of writing theorems and proofs. As
a compromise between verbosity and convenience it
was decided to rename [task_run_to_completion_threshold]
to [task_rtct] and [job_run_to_completion_threshold]
to [job_rtct].

max arrival curve + WCET ➔ max RBF
min arrival curve + BCET ➔ min RBF

The vernacular commands Opaque / Transparent change coqtop's prompt
counter without generating a prompt (for whatever reason). The proof
state recorder needs to be aware of this to avoid a out-of-sync
assertion false positive.

For debugging purposes, slow down the interaction with coqtop to maybe
trigger some potential races more reliably.

If coqtop reports a different number of interactions in its prompt
than we provided, we're out of sync.

... to comments and closing braces on lines before bulleted
sub-proofs.

For better debugging support, add

	--parse-only
and

	--parse-only --verbose
modes.

improve comments, fix names, move some stuff around

spell checker: add 'supremum' to dictionary

...and "Defined" can end one.

This can be useful for learning / teaching.

... 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.
