Subject: [PATCH] t/lib-git-daemon: try harder to find a port
As with the previous commit, try harder to find an open port to avoid
intermittent failures on busy/shared build systems.
By default, we make 3 attempts. This may be overridden by setting
GIT_TEST_START_GIT_DAEMON_TRIES to a different value.
