The rtems_test_pause() and rtems_test_pause_and_screen_number() macros
had different implementations depending on the RTEMS_TEST_NO_PAUSE
define. This define was defined to 1 by default. The user was able to
change this via the undocumented --disable-test-no-pause configure
command line option.
Pausing tests and waiting for user input contradicts the goal of having
automated test runs. Remove this feature.
Update #3818.
