Bart Oldeman eecbe8439a Adapted from Chris Rodie's patch for bugzilla #1730: 
do a device input status request for int21/ax=4406 for devices
(not for files).

Bart Oldeman a9c00dcf86 Adapted from Chris Rodie's patch (bugzilla #1729): 
"open" and "close" should call the open/close functions for devices using
a device request when appropriate.

Bart Oldeman 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)

fix for multi-segment device drivers; preserve rq_endaddr between init

Bart Oldeman 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.

Don't overwrite the critical error # with the DOS error #.
