+ *  _Internal_error_Occurred
+ *
+ *  This routine will invoke the fatal error handler supplied by the user
+ *  followed by the the default one provided by the executive.  The default
+ *  error handler assumes no hardware is present to help inform the user
+ *  of the problem.  Halt stores the error code in a known register,
+ *  disables interrupts, and halts the CPU.  If the CPU does not have a
+ *  halt instruction, it will loop to itself.
+ *
+ *  Input parameters:
+ *    the_source  - what subsystem the error originated in
+ *    is_internal - if the error was internally generated
+ *    the_error   - fatal error status code
+ *
+ *  Output parameters:
+ *    As much information as possible is stored in a CPU dependent fashion.
+ *    See the CPU dependent code for more information.
+ *
+ *  NOTE: The the_error is not necessarily a directive status code.
