commit 4f79b3e2fb3eba003240ec38a0e68702b9a60b86
Author: DJ Delorie <dj@redhat.com>

test-container: add exec, cwd
exec <path_to_test_binary> [optional_argv_0]
copies test binary to specified location and runs it from
there. If the second argument is provided, that will
be used for argv[0]
cwd <directory>
attempts to chdir(directory) before running test
Note: "cwd" not "cd" as it takes effect just before the
test binary runs, not when it's encountered in the script,
so it can't be used as a path shortcut like "cd" would imply.
cleanup: use xstrdup() instead of strdup()
