caps: is_stricty_equal() returns TRUE when comparing "ANY" and "EMPTY"
gst_caps_is_stricty_equal (caps1, caps2) will return
caps1 is an "ANY" caps and
caps2 is an "EMPTY" caps, even though
FALSE would be the expected result. This is because both have the same 'zero' length (no structures), so the current algorithm doesn't distinguish between them.
I suggest adding in an additional test for the special "ANY" case.
