test: support external memory
Add simple unit tests to test external memory support. The tests are pretty basic and mostly consist of checking if invalid API calls are handled correctly, plus a simple allocation/deallocation test for malloc and memzone. Signed-off-by: Anatoly Burakov <anatoly.burakov@intel.com>
