/*  set_vector

 *

 *  NOTE: This function is considered OBSOLETE and may vanish soon.

 *      Calls to set_vector should be replaced by calls to

 *      rtems_interrupt_catch or _CPU_ISR_install_raw_handler.

 *

 *  This routine installs an interrupt vector on the target Board/CPU.

 *  This routine is allowed to be as board dependent as necessary.

 *

 *  INPUT:

 *    handler - interrupt handler entry point

 *    vector  - vector number

 *    type    - 0 indicates raw hardware connect

 *              1 indicates RTEMS interrupt connect

 *

 *  RETURNS:

 *    address of previous interrupt handler
