f41508725d sms/pad: handle return properly 
That is, send current chr selection, and then, send LF.

2679172edf sms/vdp: implement "chrsel" hook 
This allows for outputting a character selection before it's given
through GetC. That allows a pad-oriented character selection scheme.

74de1c92cf sms/pad: implement character selection mechanism 
Still a bit rough around the edges, but still, works rather well.

Make ASCII_BS (sent when driven through kbd) make the same thing as
ASCII_DEL. Also, don't crash on filling the buffer.

2ac16d4750 sdc: check CRC during sdcReadBlk 
When there's a mismatch, retry up to a certain number of times.

This makes random problem related to assembling big kernels go away! But
it also make SD card reading much slower...

34db493496 sdc: implement CRC7 computation on cmds 
For now, this achieves nothing else than wasting cycles, but this is the
first step in enabling CRC verifications (CMD59).

I think that this is where my random problems with assembling large
kernels from SDC come from: bad data that isn't detected. If that
happens when PGM loads programs in memory, then anything can happen.

`sdct`, when ran often enough, will error out or corrupt away (go
crazy)...
