make test: detect hung tests
Run tests in a forked process with a set of pipes to communicate keep-alives and overall result. This allows us to detect when e.g. vpp dies mid-API call causing the test to hang waiting for response (which will never come since vpp died). Support setting a (per test case) TIMEOUT make test option to set timeout, with a default timeout of 120 seconds. Example - fail the test suite if any test-case fails to finish within 300s: make TIMEOUT=300 test Change-Id: I0d04f26a7232968f4bf043adf5d5b508f5018717 Signed-off-by: Klement Sekera <ksekera@cisco.com>
