tests: add test_deep_copy test
Seems to perform better than outputting to string and re-parsing it. BENCHMARK - 1000000 iterations of 'dst2 = json_tokener_parse(json_object_get_string(src2))' took 20 seconds BENCHMARK - 1000000 iterations of 'dst2 = json_tokener_parse(json_object_get_string(src2))' took 7 seconds It should make a difference on embedded systems. The test was performed on a i5 desktop CPU [~3.5 years of age]. Signed-off-by: Alexandru Ardelean <ardeleanalex@gmail.com>
