Had to change ctrl-c/ctrl-break handling again...
...
Seems to be more consistent now. read_char_sft_dev handles ^C at a fairly
high level. So raw_get_char doesn't need to worry about sft's anymore.

Improve ^C handling:
...
- ^C didn't work for int21/ah=3f. Corrected -- Do_DosIdle_loop still needs
to wait even if it doesn't call the idle int
- ^C needs to be echoed to STDOUT for low character functions (ah<0xd) but
to the device that is read from for handle functions. So we need to pass
either the STDOUT sft or that device on to the ^C echoer.
- The ^C echo really should print ^C\r\n.
- misc cleanups in break.c.
