Subject: [PATCH] testing/test_runner: Support interactive test debugging
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add support for entering interactive test debugging when DEBUG_TESTENV=1 is set
in the environment. This will execute $SHELL inside the namespace that is setup
for the test run, after setting up the test interfaces, making it easy to
manually run tests in the same environment to debug things.
