bank94: not yet in use or tested
Initial pieces to support the use of 0x94 as the secondary bank control
register as used by some of the TRS80 expansions.

trs80: split out the banking logic

p_top must be set in process.c as well for bank16k
I'm not exactly sure, but I think I found a bug in the bank16k
implementation. When ptab_alloc() calls pagemap_alloc(), p_top is not
set yet. pagemap_alloc, then proceeds to assign only one bank to the
new processes. Assuming normal copy forking, should p_top be set to
the parent's p_top *before* calling pagemap_alloc() ?
This fix seems to make my coco3 UDATA mods start working

side note: I'll be more careful about trailing white space /
indentation. Do we prefer tabs or spaces in C code? I'll change my
emacs to give the C code a bit more indentation.
