82261c0caf add_far can get away with adding 16 bit offsets only. Saves ~200 bytes!

00ef6b1be2 Eliminated long2para and avoided use of "long"s in DosExeLoader, using 
paragraphs to measure size instead. Saves ~130 bytes together.

7bf976be3f Saved ~75 bytes in printf and by elimination of fstrlen. There's only one 
call and inlining doesn't increase the size.

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)

0081bfe408 Don't call truename from FcbNameInit(). It was only necessary for "FcbRename", 
which can call it itself. This avoids yesterday's hack.

b34b68a265 FcbOpen/FcbFindFirstNext: 
Fix a consequence of truename's funny behaviour:
truename(c:nul) = c:/nul and truename(c:/nul) = c:\nul
and for FCBs it's still easiest to call truename twice
so we have to copy c:/nul back to c:nul to compensate.
This fixes the EJECT problem from Lucho.

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.

0e0abcd685 Added explicit (UWORD) type casts to avoid compiler warnings and sometimes 
save a few bytes too. Also changed the FcbParseFname return value:
returns offset portion of pointer (SI) instead of the number of bytes to
be added to SI.

5567aba08b Fixed bug #1722: dir_close() was called for normal files (via map_cluster 
and find_fat_free). This completely messed up rwblock. Removed these calls
(for directories they are already covered at a higher level) and added
a few sanity checks to dir_close and dir_write.

4f1a117069 * FAT32 kernels should ignore the upper word of the cluster number for 
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)
