Thiago de Arruda 2aa2513b8e test: Add terminal tests
- Modify tty-test to allow easier control over the terminal
- Add a new directory with various terminal tests/specifications
- Remove a pending job/pty test.
- Flush stdout in Screen:snapshot_util() (avoid waiting for the test to finish)
- Replace libuv sigwinch watcher by a sigaction handler. libuv randomly fails to
  deliver signals on OSX. Might be related to the problem fixed by
  @bbcddc55ee1e5605657592644be0102ed3a5f104 (under the hoods, libuv uses a pipe
  to deliver signals to the main thread, which might be blocking in some
  situations)
