This commit renames scope [basic_facts] into [basic_rt_facts] to
highlight the that lemmas collected in the scope are real-time (rt)
theory lemmas.

These new tactics are just shorthand for [(e)auto with basic_rt_facts].

There are quite a few places where hypotheses about the task of a job are simply stated as equality (even though a proper predicate exists). This patch replaces the equalities with the predicate.

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].

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.

improve comments, fix names, move some stuff around

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

The two concepts are tightly coupled and it does not make sense
to mix and match them. Therefore, it's cleaner and easier to
understand if both aspects of the preemption model are instantiated
in the same module next to each other.

No need to keep the two separate as they are tightly coupled anyway,
and the joint file doesn't become too long.

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.
