 *  _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.
