e9716d990d Document the fact the MSCL8 compiled kernels don't work. 
Don't initialize BSS variables anymore -- now done by the memset in main.c
Removed obsolete BYTE cfgCSYS_fnam[NAMEMAX]; config variable.
Changed cfgInit and cfgInitTail to pointers, adjusted some code to work
with them.

dd6ace383a No longer include duplicate execrh, asmsupt, and u8m/d functions for the 
init text in the Watcom compiled kernel, since they can be called "near"
in the resident code.

147f4069e4 Make CS the same for INIT and HMA text for Watcom. Move HMA text up 
in kernel.asm. Use std for the memory move: helps if there's overlap
(PCs with a very low amount of RAM).

e6e3b7a3a4 Use the "small" model for the init code (split code/data). This will enable 
us to use the same CS for resident and init code for Watcom (Borland's
too big), and share a bit.

f63eea565a Made the main fnodes far so they can be in UMBs. 
Internally the kernel uses two near fnodes though, to save on codesize
and fmemcpy's if necessary. Having memory management on two fnodes is
a little silly but I just want to make sure with the panic message
that we never accidentally try to use three near fnodes at the same time.
(two are used at the same time by rename, commit, and merge_file_changes).
This can be cleaned up later.

Anyway. 644736 bytes free conv memory isn't bad.

61d87d82bb Rename the global lpFcb variable to sda_lpFcb. Then use local lpFcb 
variables where necessary. This clears up the confusing shadowing.

2f4e2d3a69 * add support for the far jmp at "int 30" (0000:00c0) 
* mirror it for the HMA (ffff:00d0)
* put all DOS int handler (and the CPM entry jumped to from int30)
  jumpers in the "CONST" portion of DGROUP (instead of LGROUP)
  This helps Turbo C++ 1.01 make with the -S (swap) switch.
* adjustments to set the relevant PSP fields in task.c

756c578ca7 (joint with Luchezar Georgiev): add extra low disk buffer to avoid HMA 
problems with certain device driver. Add an extra space for the device
driver command line and point to a correct environment for
INSTALL= (fixes problems with xmsdsk).

      + some display tweaks
    * add ANYDOS, KBDRATE, VIDMODE, MENUCOLOR and EECHO support to the
      config.sys parser.
    * distinguish between the builtin DOS version and the settable
      DOS version.
