Fixed many warnings for unused parameters. Some cases were
a simple matter of adding "(void) param" at the beginning
of the function, while others required ensuring that addition
was inside the proper conditional section. Found with GCC's
warning -Wunused-paramter.
The test source code is generated from specification items
by the "./spec2modules.py" script contained in the
git://git.rtems.org/rtems-central.git Git repository.
Please read the "How-To" section in the "Software Requirements Engineering"
chapter of the RTEMS Software Engineering manual to get more information about
the process.
Update #3716.
Move the transition map members of the test context to a dedicated
structure. Move the transition variant pre-condition prepare, action,
and post-condition checks to a separate function to reduce the
indentation level and allow skipping of transition variants.
