(processutils is an unit from Ludo used and extended by Reinier for fpcup,
which he later extended with Runcommand variants because he still wanted to
support 2.6.0.

Some of the prototypes (though not the current code) was what spawned the
runcommand functions.

So basically they are helpers that are tied to fpcup because of its
one single commandline internal limitations (still?) and 2.6.0 legacy

Both are reasons to not use the unit in new codebases (though maybe we
should adapt some of the environment support)
