8e80462093 Be more specific about which registers are clobbered by asmsupt.asm 
functions. Preserve "ES" for Watcom.
Saves ~150 bytes resident, ~90 bytes nonresident, more for 386 kernels.

eed84806f8 dos_commit was missing a save_far_f_node() call. That caused the tar xzvf 
problem. Also fixed the case when no far fnodes are available anymore.

9db450a9b7 Remove lpOldTop variable. It is no longer necessary (has not been 
for some time) and the assignment in config_init_buffers() was
wrong (screwed up fnodes, so that buffers overlapped fnodes...).
This should fix most of the reported fnode problems.

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.

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.


git-svn-id: https://svn.code.sf.net/p/freedos/svn/kernel/trunk@818 6ac86273-5f31-0410-b378-82cca8765d1b

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.
