Implement parallel build so that all the tests in a directory should
be built simultaneously making more effective use of multiprocessor
systems. Add the --sequential command line option to disable this if
desired.

being confusing. They now both take a simple C-string argument which
names the set, and the macros check that each end matches a start of
the same name. Since tis means that a START_SET no longer takes an
argument sayng whether or notthe set is to be skipped, we now have a
SKIP macro to be used inside a set to skip to the end of it. This
is actually more versatile as we can have multiple SKIP macros in the
same set, each providing a different reason for the set being skipped.
Also removed a few obsolete/unused functions and macros.
