68c3f9ad13 Lucho reported that MSC compiled kernels now work after all. Let's mark 
those nasty "BSS" variables explicitly then to try to avoid future problems.

e9716d990d Document the fact the MSCL8 compiled kernels don't work. 
Don't initialize BSS variables anymore -- now done by the memset in main.c
Removed obsolete BYTE cfgCSYS_fnam[NAMEMAX]; config variable.
Changed cfgInit and cfgInitTail to pointers, adjusted some code to work
with them.

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.
