132b1fe579 Cluster optimizations, mainly for FAT32: eliminated checkdstart, 
replaced (cl == FREE || cl == 1) by (cl <= 1), UWORD cluster cast for FAT12/16,
and merge if branches for link_fat().

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.

* -1 is a valid offset, so we need to process the return code seperately

fedf951beb Eliminate the fnode F_DDIR flag which has no SFT equivalent: 
f_sft_idx==0xff can do the same. rwblock() is never called for directories
so the checks could be removed.

with a lot of "SVN log summarizing" help from Geraldo :-)

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 :-).
