The Classic binary semaphores without a locking protocol
(RTEMS_BINARY_SEMAPHORE) could be released by everyone, e.g. in contrast
to the POSIX mutexes (all variants) or the Classic binary semphores with
priority inheritance or ceiling, there was no owner check in the release
path.
This behaviour was a bit unexpected and not documented. Add an owner
check to the release path. Update sptests/sp42 accordingly.
This change has nothing to do with the simple binary semaphores
(RTEMS_SIMPLE_BINARY_SEMAPHORE) which have no owner at all.
Update #2725

* sp42/Makefile.am, sp42/init.c, sp42/sp42.scn: Test was testing the
wrong thing in a cpp macro. Added contents to screen file and add
documentation file.
* sp42/sp42.doc: New file.

Add sp42 to exercise thread queue with knowledge of the implementation
so we can exercise all of the normal paths possible.
* Makefile.am, configure.ac: Add sp42.
* sp42/.cvsignore, sp42/init.c, sp42/sp42.scn: New files.
