New Feature: Arbitrary deadlines.2012.2

Added support for arbitrary deadlines.

Constraint: Relative deadline must be >= exec cost.

Use: Set relative deadline in rt_task::rdeadline. Set value to 0
     to default to implicit deadlines.

Limitations: PFAIR not supported by this patch. PFAIR updated to
     reject tasks that do not have implicit deadlines.
