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.

- ^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.

inthndler.c, chario.c, break.c simplifications and cleanups.
Pass a near pointer to the far pointer that points to the device instead
of an SFT index (in general).
Make cooked_write much faster by only testing for input every 32
characters.
No longer test for ctl_s on syscon if writing to the printer: just
read from the printer which will return zero characters.
Fix reading/writing zero characters by returning "256" (special code).
Adjust interfaces in other files.
