[PATCH 0/4] Red-Black Tree API Changes

[Gedare Bloom]

This patch series (duplicating 2 earlier patches sent) updates the public
red-black tree API with new unprotected versions of some functions and
applies a convention of using no protection (preemption is enabled) for
any function that does not have an unprotected variant. In the process
I also eliminate the _RBTree_Peek and _RBTree_Peek_unprotected functions,
with the latter being replaced by _RBTree_First and the former no longer
necessary. Now no protected function is available to obtain without removal
the minimum / maximum node in a red-black tree.

Gedare Bloom (4):
  score/scheduling: Use RBTree_First instead of Peek in EDF scheduler.
  score/rbtree: replace _RBTree_Peek_unprotected with _RBTree_First.
  rbtree: API Changes
  score/rbtree: eliminate unused function _RBTree_Peek.
