* gst/gstvalue.h:
add support for subtracting values from each other. Note that
subtracting means subtracting as in set theory. Required for caps
stuff above.

* testsuite/caps/erathostenes.c: (erathostenes), (main):
* testsuite/caps/sets.c: (check_caps), (main):
* testsuite/caps/subtract.c: (check_caps), (main):
add tests for subtraction and equality code.
