If there is already a file with a long file name it isn't possible to
create a second file which has a name that ends on the first files name
(for example ets.beam and sets.beam). This patch fixes that.
Update #3258.
Use a self-contained recursive mutex for API_Mutex_Control. The API
mutexes are protected against asynchronous thread cancellation.
Add dedicated mutexes for libatomic and TOD.
Close#2629.
Close#2630.
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.
Thread priority changes may append or prepend the thread to its priority
group on the scheduler ready queue. Previously, a separate priority
value and a prepend-it flag in the scheduler node were used to propagate
a priority change to the scheduler.
Now, use an append-it bit in the priority control and reduce the plain
priority value to 63 bits.
This change leads to a significant code size reduction (about 25%) of
the SMP schedulers. The negligible increase of the standard priority
scheduler is due to some additional shift operations
(SCHEDULER_PRIORITY_MAP() and SCHEDULER_PRIORITY_UNMAP()).

We must not clear the priority updates in _Thread_queue_Extract_locked()
since this function is used by the priority ceiling surrender operations
after the ceiling priority handover from the previous owner to the new
owner. This is especially important in SMP configurations.
Move the _Thread_queue_Context_clear_priority_updates() invocation to
the callers.
Close#3237.
The thread queue extract operations performed by the
_Thread_queue_Flush_critical() may result in a priority change of the
thread queue owner. Carry out the scheduler priority update operation.
This is especially important in SMP configurations.
Close#3236.
The _Semaphore_Get_operations() must return the proper operations for
priority inheritance semaphores.
Add a test case for rtems_semaphore_flush() with priority inheritance.
Close#3235.
The link time wrap of printf leads to unresolved symbols in the loadable
modules. This resulted in infinite loops and test timeouts. Use
rtems_printf() for output.
Update #3199.
- Remove the macro defines and the need for tmacro.h by remapping the
symbols using ld's wrap option.
- Remove FLUSH_OUTPUT, it was empty.
- Move rtems_test_exit to libmisc/testsupport as a function.
Update #3199.
Provide functions to get the version string, major, minor and revision
numbers and the version control identifer that is a unique tag for
the version control system.
Update #3199.
Remove POSIX_API_Control::created_with_explicit_scheduler. Add
Thread_Control::was_created_with_inherited_scheduler. This fixes also
pthread_getattr_np() for Classic tasks.
Update #2514.
