blockdev: protect IX in routines

Sure, it's a bit slower, but it prevents a lot of hard to debug
problems. I don't have to want to remember "don't use IX if you
have any blk* calls". Let's optimize I/O later.

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)...

That was an interesting bug. It didn't cause a problem in emulation, but
in an RC2014 on an SD card, an include that didn't end with two newlines
would cause an infinite loop.
