* @brief Tests some @ref RTEMSAPIClassicIntr directives.
*
* This test case performs the following actions:
*
* - Validate the interrupt lock directives.
*
* - Check that RTEMS_INTERRUPT_LOCK_REFERENCE() expanded to a lock reference
* definition. Check that the lock is available after static
* initialization.
*
* - Check that the lock is available after initialization.
*
* - Check that maskable interrupts are disabled before the call to
* rtems_interrupt_lock_interrupt_disable() and disabled afterwards.
*
* - Check that the maskable interrupt status is not changed by the
* rtems_interrupt_lock_acquire_isr() call. Check that the lock is no
* longer available.
*
* - Check that the maskable interrupt status is restored by the call to
* rtems_interrupt_lock_release() according to the ``_lock_context``
* parameter. Check that the lock is available afterwards.
*
* - Check that the maskable interrupt status is not changed by the
* rtems_interrupt_lock_destroy() call.
*
* - Initialize the lock using rtems_interrupt_lock_initialize(). Check that
* the lock is available after initialization.
*
* - Check that maskable interrupts are disabled before the call to
* rtems_interrupt_lock_acquire() and disabled afterwards. Check that the
* lock is no longer available.
*
* - Check that the maskable interrupt status is restored by the call to
* rtems_interrupt_lock_release() according to the ``_lock_context``
* parameter. Check that the lock is available afterwards.
*
* - Check that the maskable interrupt status is not changed by the
* rtems_interrupt_lock_destroy() call.
