Patch registers SIGTSTP hook where it sends reset terminal color
control sequence using write and fsync.
Handler is installed only if signal is not being ignored.

Patch uses rl_free_line_state and rl_cleanup_after_signal to unhook
readline from terminal, then it calls original TSTP handler using
approach in URL below and again hooks readline using

Handling is based on code from:

This approach seems to mostly work. User is sometimes able to get
readline into state when it doesn't correctly respond to newline.
^Z and subsequent fg helps there as reset command helps broken
terminal. I haven't noticed this using previous approach copied from vi.
If you know what is going on I'll be more than happy to fix it.
