- (make check): GNU coding standards-compliant primary entry point,
running all available tests in the best environment (i.e. Docker
container).
- (make test-all-local): Local entry point, running only tests
which do not require a special environment; intended for IDE
integration and quick turnaround cycles.
Also modifies the Travis configuration to run (make check), to prevent
duplication.
