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

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

cf2ed6752b Had to change ctrl-c/ctrl-break handling again...

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.

f63eea565a Made the main fnodes far so they can be in UMBs. 
Internally the kernel uses two near fnodes though, to save on codesize
and fmemcpy's if necessary. Having memory management on two fnodes is
a little silly but I just want to make sure with the panic message
that we never accidentally try to use three near fnodes at the same time.
(two are used at the same time by rename, commit, and merge_file_changes).
This can be cleaned up later.

Anyway. 644736 bytes free conv memory isn't bad.

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.
