  assert: allow non-int returning functions to assert Include GIT_ASSERT_WITH_RETVAL and GIT_ASSERT_ARG_WITH_RETVAL so that functions that do not return int (or more precisely, where `-1` would not be an error code) can assert. This allows functions that return, eg, NULL on an error code to do that by passing the return value (in this example, `NULL`) as a second parameter to the GIT_ASSERT_WITH_RETVAL functions.
