Clarify and implement parts of the correct SHARE behaviour.

* Flip \ to / where possible.
* Introduce $(DIRSEP) (/ or \) for use inside commands in makefiles
where / won't work in DOS.
* Override various settings for Linux in owlinux.mak.
* Add quotes in exeflat.c to avoid shell expansion of $$$$$.
* Let "make all", "make clean", and "make clobber" do the job.

but useful for people who are used to writing HIGH everywhere.
Thanks to Christian Wallbaum the hint that config.txt had both.
Removed code which called int 16.1 in a loop before 16.0 - this
would only be useful if you invoke HLT before each int 16.1 ...

RBIL, DRDOS would even hook int 1a ah=4 to force a correct year.

you reboot while files are open... Reported by Hardi Stengelin :-).
Always test *link_fat* result. New function is_free_cluster. Extra
checks in *link_fat* (bad r/w offset, i/o, write) and *next_cluster*
(dangling chain: bad value in chain) with short messages (no msg for
bad chain start). Shorter "Bad DPB" (FAT size) msg. More comments!
Update FS INFO on disk only when needed. Check if chain EOF was at
expected place when extending. Call *link_fat* before! *setdstart*
when a FAT chain grows. [Q: Does 0 byte write always trunc? Why?]

the virtual / created-by-subst drive when it resolves relative
paths, even though truename returns the "real" drive and dir
of where your files actually are in the end. Using the current
directory of the "real" drive made truename give wrong results.
PS: If "subst e: d:\" says "physical path x:\ cannot be made",
then it refers to "making" a root dir. "subst e: d:\foo" works.

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").

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.

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.

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 :-).
