Transmit DisplayFrameSync message, handle in WaterfallSpectrum.
...
More kludginess, especially around initialization and timing. But it addresses the flickering lines of pixels at the bottom of the waterfall scroll area!

Transmit ChannelSpectrum data through separate FIFO.
...
Allows handling of data during LCD "vertical retrace", independent of other baseband->application messages. A bit kludgy still...

Hard-code K=8 FFT twiddle constants for now.

So low on baseband RAM! This eliminates the sin_f32() function and table, which is only used in the FFT, for the moment.

Remove LOCATE_IN_RAM from DMA IRQ handler
...
Not needed for M4, was causing code to be located in data RAM, and veneers to jump between code and data RAM. Reclaimed a few hundred bytes of code RAM.

Un-bitfield PinConfig, GCC 5 didn't like it.
...
And GCC 4.9 was very touchy about it. Attempts to fix by other means broke MAX2837 register readback (but not writing?). It suggests there might be a deeper issue -- setup/hold timing?

TODO: Improve resolution to milliseconds or better.
TODO: Work back from end of packet to compute timestamp for beginning of packet.
TODO: Reuse ChibiOS RTC code, which isn't used now because ChibiOS on M0 core is responsible for RTC configuration, and including ChibiOS RTC API on M4 will also try to initialize/manage the peripheral.
