Convert setvec into a function that disables/enables ints (init code only
for now, resident code will follow later); cli/sti (disable/enable) are
now macros (inlined).

field, simplifies remove_lfn_entries(), and avoids a bug if you delete
the first entry in the root directory on FAT32.

all other compilers can use it with pascal or "register" calling conventions.
Saves ~50 bytes for the init code.

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.

extend() now uses f_cluster instead of f_back, while map_cluster makes
sure it's not set to LONG_LAST_CLUSTER (but to the cluster before it)
when calling extend().
extend() and first_fat() now return the new cluster number or
LONG_LAST_CLUSTER, just like find_fat_free()
Hopefully I didn't break anything... Initial testing was successful.

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.

FAT16 partitions (just like FAT16 kernels do)
* added extra checks to make sure that invalid FAT entries are never
followed
* made put_console() public to be able to print a message in case of
FAT corruption
* some small optimizations and header cleanups (some suggested by Arkady)

This solves problems with int24 handlers that call int21/ah=59.
Let truename and blockrw return with an error if there is a critical error.
Don't overwrite the critical error # with the DOS error #.

* 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

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).

* add sanity check to initdisk.c for (driveParam->chs.Sector == 0)
+ 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.
