194aa09e69 exeflat.c reorganization part 2, still no functional changes.

94085ce923 Changed copy() to use a two pass algorithm: Now SYS first calls 
copy to read kernel and command.com into RAM, then updates the
boot sector, then calls copy again to write kernel and command
from RAM to disk. This reduces disk changes a lot when you do
SYS A: B: on a PC which only has 1 diskette drive ("DJ style").

94d0560e7b Do not ABORT if image size is above 1 MB - Instead, handle size 
MODULO 1 MB (paras = low_16_bits(pages<<5) ...) because for e.g.
Turbo C++ 3.0 needs this: Their IDE is 1.3 MB BOSS NE style EXE,
the first < 0.3 MB load a DOS ext which loads and runs the rest.

f7320f6452 Init HaltCpuWhileIdle to 0 before installing int handlers. 
Removed HaltCpuWhileIdle handling from GetBiosKey because it is
only used *before* IDLEHALT is processed anyway - in the config
sys menu *and* in CheckContinueBootFromHarddisk. Adding s.th.
like "switches /i" would be a way to enable it a bit earlier.

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 :-).

65798a9203 Clarified description of 21.63 (country / nlsfunc), 21.71 
(long file names) and 21.5d0x (share). The share extensions
need both SHARE and kernel extensions, neither are done yet.

c2fababb01 Reverted the "add new IRQTEXT" segment patch from 1324->1325 
again, as this made the kernel crash in Bochs in PostConfig
(or short before or after it). FASTBOOT should still be okay.
