9e694ce836 AIS decoding and really bad UI.
The decoder needs a serious refactoring/decoupling.
The UI just dumps bits of the received packets into a console window, whcih scrolls too quickly in an AIS-dense area with a good antenna.

a366b3ac4f CRC class.
Has some more efficient code, commented out because I was having trouble getting it to work. However, it may have been due to the particular data I was trying to decode and CRC-validate.

51df92a05a Rename baseband_ais -> ais_baseband.
So that ais_baseband and ais_application filenames can be sorted near each other.

f82fd1f8d7 Tease apart utility.hpp, other header dependencies.
Trying to get a host-testable FSK demodulator, and finding a lot of M4- and ChibiOS-specific code is getting included. Boo.

f1ca3fe5bb Switch RFFC5072, MAX2837 back to 40MHz reference.
Turns out the MAX2837 can't tune the necessary range when given a 50MHz reference. Oops.

19764ce693 Swap function of P2_8, P2_4 in schematic, firmware, CPLD.
gpio_unused: P2_4 -> P2_8
gpio_lcd_rd: P2_8 -> P2_4
P2_8 is a very long line, shared with DFU button.
Revise schematic to match CPLD signal names.

035ec84f04 Wrap MessageQueue.push() with mutex.
This addresses issue #61, occasional FIFO/data corruption. With the mutex, any thread on one core can write to the FIFO. But still, only one thread on one core should read from the FIFO.

7937ea7327 Enable DMB instruction at end of FIFO data copy.
Can't hurt to make sure FIFO and buffer state are flushed before returning to caller...

Still doesn't seem like the right place, but better than the event dispatcher!

45d26abf10 Use correct memory region for persistent storage.
Turns out 0x10088000 - 0x10089fff is not the right place. It's 0x40041000, and is only 256 bytes!
Move PPM to correct place, change representation to PPB for finer control.
Reset PPB value to initial value if read value out of bounds.
Clip PPB value on write to permitted bounds.
Contributes to resolution of issue #11.
