It was a parameter but that wasn't of any use,
it was just making everything more noisy.

This way, an addition in external libraries
cannot shadow a definition in Prosa.

Remove the use of ideal uniprocessor schedules in a couple of places where
it's not actually required.

Also fix some coqdoc styling issues while at it.

Move everything into the new namespace starting with 'prosa' rather
than the bland 'rt'.

The main restructuring thrust is nearing completion, so let's get rid
of the `restructuring` namespace.

This is not yet the final organization, but already an improvement.

Move main high-level results to separate top-level `results` module.
Rationale: Let's make it very clear where to find the main, high-level
results in Prosa, and at the same time let's declutter the analysis
namespace.

Other notable change, apart from moving files around:

- move two key analysis definitions to analysis.definitions
- split RBF definition and facts into separate files
- move facts about ideal schedule to ideal_schedule.v

This fixes all warnings about ambiguous module names and resolves #49.

It also highlights that we still need to cut down on superfluous
Require Import commands in recently ported files.
