-------------------------+-------------------------
 If for any reason a user sets the interrupt level in the mode on an SMP
 build the error {{{RTEMS_UNSATISFIED}}} is returned. The documentation
 indicates this is a lack of stack and this confusing.

 The reason this happens is the SMP check for an interrupt level being set
 is in the score's {{{_Thread_Initialize}}}. I propose that and
 {{{is_preemptible}} check be converted to an {{assert}} and checks be
 added to the Classic API to catch these errors and report suitable error
 codes.

 There is no meaningful error code available without abusing an existing
 one so I propose adding {{{RTEMS_INVALID_MODE}}}.
