6947542a5e Initialise all int vectors except the ones at 70:xxxx using a table. 
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).

ecfcb9be29 dir_read() no longer updates the diroff counter. This eliminates the NEW 
field, simplifies remove_lfn_entries(), and avoids a bug if you delete
the first entry in the root directory on FAT32.

126ef5cec9 Inlined much of getFATblock() into link_fat. Saves the idx reference. 
The second call (for a FAT12 entry that is divided in two sectors)
can be much simpler, no need to recalculate.

f6716cd74b "clussec" can be of CLUSTER size if we divide by an adjusted "words per 
sector"(FAT16), or "dwords per sector"(FAT32) value instead of multiplying
it first. For FAT12 the *3/2 works out a little differently: here we
first multiply by 3 and then divide by the number of "nibbles per sector".

0afa773303 From Lucho: HMAFree == 0xfff0 - bytesToAllocate is valid and may happen 
if the buffers occupy exactly all HMA space up to and including the
last byte at ffff:ffff. Failing caused all buffers to go low ...

cf2ed6752b Had to change ctrl-c/ctrl-break handling again... 
Seems to be more consistent now. read_char_sft_dev handles ^C at a fairly
high level. So raw_get_char doesn't need to worry about sft's anymore.

f94ba5ebe1 Improve ^C handling: 
- ^C didn't work for int21/ah=3f. Corrected -- Do_DosIdle_loop still needs
  to wait even if it doesn't call the idle int
- ^C needs to be echoed to STDOUT for low character functions (ah<0xd) but
  to the device that is read from for handle functions. So we need to pass
  either the STDOUT sft or that device on to the ^C echoer.
- The ^C echo really should print ^C\r\n.
- misc cleanups in break.c.
