 Added definitions and implementation of jitteraware RTA for uniprocessor scheduling.  The Prosa directory was restructured to better accomodate the different types of arrival sequences and schedules.

 Add generic definition of job suspension based on the cumulative service  Define the dynamic suspension model (based on task suspension bounds)  Add suspension semantics for uniprocessor schedules  Formalize reduction from suspensionaware schedule to suspensionoblivious schedule by inflating costs (works with JLDP policies and nonunique priorities)  Formalize suspensionoblivious FP RTA using the reduction  Add implementation of a concrete suspensionaware scheduler  Test suspensionoblivious FP RTA with an actual task set  Add simpler definition for JLFP policies  Generalize busy interval lemmas from FP to JLFP scheduling

This commit contains several updates related to uniprocessor scheduling.  Basic definitions of uniprocessor scheduling (see model/uni)  Definitions of worload and service for generic sets of jobs (see service.v and workload.v in model/uni)  Definitions and lemmas about busy intervals (see model/uni/basic/busy_interval.v)  Definition of an arrival bound for sporadic tasks (see model/arrival_bounds.v)  Definitions and correctness proofs of the RTA for FP scheduling (also works with nonunique priorities and arbitrary deadlines, but gives pessimistic bounds)  Implementation of the FP RTA to check for contradictory assumptions In addition, we have also defined partitioned scheduling and proven how it relates with uniprocessor (see model/partitioned).

We use simpler, more pessimistic interference bounds to prove that Bertogna and Cirinei's RTA works for parallel jobs.

 Implemented concrete job and tasks.  Added a periodic arrival sequence.  Created examples of applying a schedulability test to small task sets and concluding that no task misses a deadline.

 Now we have two definitions of work conserving, a simple version and another one based on count, along with a proof of equivalence.  Implemented a concrete scheduler (basic and jitter)

 Removed unnecessary assumption in RTA about task precedence/no intratask parallelism.  Scheduler models and analyses are organized in separate modules/folders.  Added RTA for FP and EDF for schedulers with release jitter.  The scheduling invariants were split into more finegrained assumptions: (a) scheduler is workconserving (b) scheduler enforces FP/JLDP priority X  New helper lemmas about counting, and sorted/uniq lists  Inclusion of tactics feed and feed_n (see documentation).  Added a Makefile generator
