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.

9db450a9b7 Remove lpOldTop variable. It is no longer necessary (has not been 
for some time) and the assignment in config_init_buffers() was
wrong (screwed up fnodes, so that buffers overlapped fnodes...).
This should fix most of the reported fnode problems.

69faceffe5 int21/ah=26: new_psp now copies the old psp and just sets a few fields 
int21/ah=55: child_psp does the rest
init code does the init (fixed values are always copied now)

de444743cc Define I386 and I186 more cleanly. 
Add (UWORD) casts to silence the compiler.
Optimize (head*sector) to secs_per_cyl
Add BORLANDC to compiler list and simplify startup printf to one message.
#pragma enable_message(130) for Watcom C causes it to behave a little more
like Borland in terms of warnings.

a0f4465045 From Eric Luttmann: 
fix for multi-segment device drivers; preserve rq_endaddr between init
calls for the same driver.

8db46073f9 From: Eric Luttmann <ecl@users.sourceforge.net> 
Fix for multisegmented device drivers: If there are multiple device
drivers in a single driver file, only the END ADDRESS returned by the
last INIT call should be the used.  It is recommended that all the
device drivers in the file return the same address.
This fixes a load problem with DUSE.

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
