staging: speakup: flush tty buffers and ensure hardware flow control
This patch fixes the issue where TTY-migrated synths would take a while
to shut up after hitting numpad enter key. When calling synth_flush,
even though XOFF character is sent as high priority, data buffered in
TTY layer is still sent to the synth. This patch flushes that buffered
data when synth_flush is called.
It also tries to ensure that hardware flow control is enabled, by
setting CRTSCTS using tty's termios.
