Starts taking steps towards SMS/GG and V9938/9958 support.
...
Specifically: routine namespace stuff, plus the intention to move to a table-based operation+cost version of timing. Reordering works fine for the TMS, and probably would also for the SMS/GG, but it'd be problematic with the command engine of the V9938/9958 and maintaining a consistent set of code is easier.

Audio works now. Though I still need properly to confirm who owns dividers in practice. I think probably all division should be within the SN.
