7eb9514377 Move the ddt bitfields to df_descflags. Let SetLogDev call GetLogdev, 
eliminating common code.

5d712fc2a6 Avoid bitfields for fnodes, using flags instead. 
Replaced droot field by checks for f_dirstart == 0.

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.

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.

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...).

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.

that case we should set the current cluster to FREE even if it is
currently a LONG_LAST_CLUSTER.
