[svn-r29957] Changes to cache_api.c

- Cleaned up mixed tabs and spaces that mis-aligned brackets.
- Test functions now return hbool_t to match the global pass variable.
- Main now returns EXIT_SUCCESS/EXIT_FAILURE.
- The invalid_configs array is now allocated dynamically instead
  of statically. This reduces the frame size, removing some
  warnings and making it easier for platforms/compilers that
  have frame size issues (e.g.: zOS).

Tested on: 64-bit Ubuntu Linux w/ gcc 5.3.1
           Autotools serial
