sapi: New implementation of rtems_panic()

The previous rtems_panic() implementation was quite heavy weight.  It
depended on _exit() which calls the global destructors.  It used
fprintf(stderr, ...) for output which depends on an initialized console
device and the complex fprintf().

Introduce a new fatal source RTEMS_FATAL_SOURCE_PANIC for rtems_panic()
and output via vprintk().

Update #3244.
