*	score: Rework thread priority management	Sebastian Huber	2016-09-21	1	-7/+134
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Add priority nodes which contribute to the overall thread priority. The actual priority of a thread is now an aggregation of priority nodes. The thread priority aggregation for the home scheduler instance of a thread consists of at least one priority node, which is normally the real priority of the thread. The locking protocols (e.g. priority ceiling and priority inheritance), rate-monotonic period objects and the POSIX sporadic server add, change and remove priority nodes. A thread changes its priority now immediately, e.g. priority changes are not deferred until the thread releases its last resource. Replace the _Thread_Change_priority() function with * _Thread_Priority_perform_actions(), * _Thread_Priority_add(), * _Thread_Priority_remove(), * _Thread_Priority_change(), and * _Thread_Priority_update(). Update #2412. Update #2556.
*	score: Add deadlock detection	Sebastian Huber	2016-07-27	2	-39/+379
\| \| \| \| \| \| \| \| \| \|	The mutex objects use the owner field of the thread queues for the mutex owner. Use this and add a deadlock detection to _Thread_queue_Enqueue_critical() for thread queues with an owner. Update #2412. Update #2556. Close #2765.
*	score: Fix CORE mutex initialization	Sebastian Huber	2016-05-12	4	-0/+304
	The priority inheritance and ceiling CORE mutexes wrongly used the FIFO queueing discipline. Delete misleading _CORE_mutex_Is_priority(). Bug introduced by 1e1a91ed11458ddbb27b94d0001d8f0fc2ef7a97. Add test sptests/spmutex01, since no existing uni-processor test covered the thread priority queueing discipline for CORE mutexes.
