* itron/include/rtems/itron/task.h, itron/src/cre_tsk.c,
posix/src/pthreadcreate.c, rtems/src/taskcreate.c,
rtems/src/taskdelete.c, rtems/src/timerserver.c,
score/src/threadclose.c, score/src/threadcreateidle.c,
score/src/threadinitialize.c: Switch task create and delete
operations to using API Allocator Mutex. This moves almost all uses
of the RTEMS Workspace from dispatching disabled to mutex protected
which should improve deterministic behavior. The implementation was
carefully done to allow task create and delete extensions to invoke
more services. In particular, a task delete extension should be able
to do mutex and file operations.
