054631c300 Ported COUNTRY.SYS support from the unstable branch. 
Simple country support is kept: COUNTRY=31 will look for country.sys but
if it does not exist, not complain and load the built-in info.

* merge unstable kernel optimizations
* enable seek for int2f/AX=1228
* -1 is a valid offset, so we need to process the return code seperately

2092745236 Force near fnode use to use either fnode[0] or fnode[1] instead of the 
allocation scheme. This eliminates the checks done in inthndlr.c because
the f_count field is no longer checked.

ab53a50c49 Mktemp (21.5a) only inserts leading backslash in temp file name 
if no directory given in template if DOS version is 5.
Older and newer DOS versions just use no dirspec in that case.
This helps ftp.sac.sk/pub/sac/pack/iup067.zip exepacker which
tries to rename the temp file to a file in current directory.

Prepared Truename (21.60) to return 0 if okay, 3a00 if char dev
(and not JOIN / network?). May need further coding to actually
have the intended effect...? Note: The shell TRUENAME command
may change names for display!

Changed the "true DOS version" for FAT16 kernels from 5.0 to
6.22 to reflect the updates in 21.5a and 21.60, other 5 / 6
differences are not simply in the kernel but more in COUNTRY,
KEYB, HIMEM, SMARTDRV, DBLSPACE, EMM386, COMMAND and so on.
In addition, 6.22 is a popular version number to report :-).

cf2ed6752b 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.

f94ba5ebe1 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.
