Dispersal of internal thread handler resulted in IDLE thread becoming
...
part of the Thread Handler. This required the name of the optional
CPU dependent IDLE thread implementation to change.

MPCI Receive became a thread and the prototype changed.

Removed the internal thread objects and dispersed its contents to
...
the thread handler (IDLE), MPCI object (SYSI now MP Receive)
and initialize_executive_early (IO initialization). The SYSI task
no longer exists in a single processor configuration. This reduces
single processor Workspace requirements by a TCB and a stack which
is often larger than the minimum stack size. Moving the IO initialization
plus accompanying BSP hooks eliminated an initialization ordering problem
in which a global task could be created before the MPCI was initialized.
