Takes a repeat shot at proper shadowing.
I think the Apple IIgs Technical Reference explains how these bits interact, and I just had inhibit_all_pages off all on my own.

Gives the two sets of switches responsibility for supplying 'state'.
(And fixes language-card state value.)

Also reduces memory map logging.

Corrects interpretation of bit 3 of the state register.
And attempts to be a bit more careful with the language card in general.

Shifts size-limiting of X and Y to transitions and mutations, away from reads.
Primarily to remove potential bug-causing complexity — this is easier to debug. But let's see.

Attempts retroactively to enforce the rule that 8-bit index modes => no top byte.
(Rather than a preserved but ignored top byte)

Hits a few other easy cases.
Still to do: card paging, and finding out which banks that applies to, and shadowing. So: everything with flags.

As testing would be rational.
