See individual commits:
- sysdeps: Remove trailing NUL from command lines from /proc
- tests: Build test-sleep-forever even if embedded tests are disabled
- tests: Add a unit test for _dbus_command_for_pid()
- sysdeps: Return an error for _dbus_command_for_pid on Windows
- tests: Assert that _dbus_command_for_pid() has correct error behaviour
Closes #222 (closed)
