9cbede2ec9 Stop abusing "idx". The OW optimizer likes this better, too.

00e1527fc5 Clean up FAT12 handling -- there's a portable approach that's small too.

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.

bfe9252c2b Merged next_cluster and link_fat into one function depending on a 
special Cluster2 value. More optimizations later.

115b2bf68d Calculate the nibble/word/dword index of the FAT entry in the sector 
centrally in getFATblock.

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.
