CONFIG_DONT_PREEMPT_ON_TIE: Don't preeempt a scheduled task on priority tie.wip-performance
Added the compilation option CONFIG_DONT_PREEMPT_ON_TIE. In the event of a priority tie, a task that is currently scheduled is favored over one that is not. If both tasks are scheduled (or both are not), then tie breaks on PID and inheritance still hold. Configuration option includes a warning that schedulability analysis that depends upon task-id/PID tie-breaks breaks when CONFIG_DONT_PREEMPT_ON_TIE is enabled. Pfair/PD^2 not supported.
