Output only the basename of source files to be independent of the build
system source paths.
In the future it may be better to use the GCC -fmacro-prefix-map option.
This option is available in GCC 8 and later. It is not yet available in
clang.
Update #3818.
This ensures that lines are output atomically if they are produced by
different other contexts, e.g. interrupts, other processors, other
threads.
Update #3199.
Add rtems_scheduler_get_processor_maximum() as a replacement for
rtems_get_processor_count(). The rtems_get_processor_count() is a bit
orphaned. Adopt it by the Scheduler Manager. The count is also
misleading, since the processor set may have gaps and the actual count
of online processors may be less than the value returned by
rtems_get_processor_count().
Update #3732.
Add rtems_scheduler_get_processor() as a replacement for
rtems_get_current_processor(). The rtems_get_current_processor() is a
bit orphaned. Adopt it by the Scheduler Manager. This is in line with
the glibc sched_getcpu() function.
Deprecate rtems_get_current_processor().
Update #3731.
One reason to move the test support into a dedicated library are the
standard output __wrap_*() functions. They may conflict with
application level wrappers.
Update #3199.
