Fixed case where blocked tasks are released.

Fixed bug where AUX tasks were being added to the
ready queue while those AUX tasks were actually blocked.
Bug stems from the fact that the AUX tasks do not
make themselves realtime, but another thread does this
instead. Also fixed minor bugs elsewhere.

NOTE: ONLY FIXES C-EDF.  OTHER PLUGINS REMAIN TO BE FIXED.
