05cd65a193 Merge find_fat_free() and extend() -- they were almost identical. 
Have a simplified clause for f_cluster == FREE.
Set f_cluster = FREE in shrink_file if the file is set to 0 bytes; in
that case we should set the current cluster to FREE even if it is
currently a LONG_LAST_CLUSTER.

ce290a033f Eliminate f_back field. 
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.

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.

a few sanity checks to dir_close and dir_write.

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.

b0e54ff704 (with a little help from Arkady) 
inthndler.c, chario.c, break.c simplifications and cleanups.
Pass a near pointer to the far pointer that points to the device instead
of an SFT index (in general).
Make cooked_write much faster by only testing for input every 32
characters.
No longer test for ctl_s on syscon if writing to the printer: just
read from the printer which will return zero characters.
Fix reading/writing zero characters by returning "256" (special code).
Adjust interfaces in other files.
