Rename AISModel to AISLogger.
...
That's really what it is. Also move receiver initialization to AISView. It'll eventually move further out to an AISApp, once I figure out what an App looks like...

Move SGPIO configuration and control to baseband firmware.
...
Addresses long-standing and annoying bug where SGPIO DMA channel would not disable -- and not configure cleanly next time it was needed. My theory is that the DMA channel couldn't disable until it got a request from the peripheral, and sometimes the peripheral was disabled before that last request.
Anyway, the baseband firmware should control the SGPIO, methinks, despite the impact on baseband code size.

Methods to peek and skip messages in queue.

Allows receiver to not consume a message until after it's handled. And that enables the transmitter to block until the queue is empty, knowing that when unblocked, all messages in queue have been handled.

Rename GPDMA channel disable_force() to disable().

There was nothing particularly forceful about the disable_force() code. Whether it's a "forced" operation depends on what happens before and after (HALT and ACTIVE flags are involved in a smooth disabling of the channel).
