1e5efe260e New config.sys (config.c, config.txt) options: IDLEHALT=n to activate 
"HLT on idle" (dosidle.asm, int2f.asm) and KEYBUF=n[,m] to relocate
the keyboard buffer to another area in the 40:ac..40:1ff range. Global
functions and variables: proto.h DosIdle_hlt, init-mod.h and globals.h
DosIdle_hlt() and HaltCpuWhileIdle.

68c3f9ad13 Lucho reported that MSC compiled kernels now work after all. Let's mark 
those nasty "BSS" variables explicitly then to try to avoid future problems.

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.

6e6e34024b Make UMB_get_largest "pascal". Let it use the xms driver address from 
the HMA code. Misc small config.c cleanups.
The uncompressed 386/fat32 kernel is now below 70000 bytes (69896).

950078ad08 Use the pascal calling convention for most intr.asm functions, and let 
them pop the stack (smaller code than using bx).
Tell Watcom which registers are clobbered; save some more registers
for intr() -- especially for intr() this helps.

7ae98cee2a Introduce VA_CDECL: only Turbo C 2.01 needs an explicit cdecl for printf, 
all other compilers can use it with pascal or "register" calling conventions.
Saves ~50 bytes for the init code.

8e80462093 Be more specific about which registers are clobbered by asmsupt.asm

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.

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

439cc495e4 * add FILESHIGH, LASTDRIVEHIGH, and STACKSHIGH and DOSDATA=UMB 
to load these structures into UMBs
    * make DOS sub-MCBs visible (seen by MEM)
    * preliminary allocation of FILES etc. now takes place at the
      top of conventional memory, and device drivers are loaded before
      the final allocation takes place.
    * handle multiple UMBs more correctly (but config.sys can use
      only one UMB for devicehigh -- /Ln,xxxx is not yet implemented)
