replaces `int32_t x_position` with `PCDIMENSION *xdim` (and similarly for y,z,m) in PCSCHEMA to get a direct access to the corresponding dimension
-> code readability improvement by discarding the `-1` constant and maybe slight expected performance increase of get/set functions
- definition of CU_ASSERT_FAILURE and CU_ASSERT_SUCCESS for easy checking of return values in tests.
- pcpoint_set functions were returning the PC_SUCCESS/PC_FAILURE as a double (!)
- add simple xy, xyz, xym and xyzm xml schemas for unit tests (test_point_xyzm)

The function was written by Remi-C and slightly modified by me
to avoid the check for NULL and be const-correct.
Also I've added a unit test for the new library function.
