Moving internal functions in testfun/ directory to test/ directory

[Rik]

All,

Is there any objection to moving the following internal functions from the
scripts/testfun directory to test/private?

__run_test_suite__.m
__printf_assert__.m
__prog_output_assert__.m

These functions are only used when running the 'make check' test suite and
don't really need to be installed and visible to every installation.

Only downside is that if you want to run one of the test in the test/
directory you will need to execute "addpath ($srcdir/private)" first.  We
could also modify run-octave.in to automatically include this.
