When the receive timeout happens, the radio may still interrupt while
the SPI bus is getting shut down. If this happens, the interrupt
handler shouldn't touch the SPI bus at all as it may well be turned
off, which would cause the receive function to wedge waiting for a spi
byte transfer to happen.

When monitoring telemetry, the frame needs to be sent together on one
line, not split with the output of a command (like 'a') mixed in.
Use a mutex for products with monitoring to keep command output and
telemetry output each on separate lines.

The 'hide' value wasn't getting reset to 'false' each time the state
of the indicators was checked, so indicators would get hidden and then
never shown again.

ao_delay() is implemented on top of ao_sleep_for, and ao_sleep_for
uses the timeout value of 0 to indicate an infinite timeout. Calls to
ao_delay for 0 ticks would unintentionally hit this case and end up
waiting forever.x

Instead of polling the device for fifo space, just use the available
pin configuration to figure out if there is enough space for a single
APRS buffer. Then set the APRS buffer size to match the fifo threshold
setting in the chip so that we know we can write the whole APRS buffer
once the pin says there's space.

This provides inline functions for sending and receiving individual
bytes, and setup/finish functions to wrap them in. This make the byte
sending respect the SPI hardware interface requirements.

This regularizes SPI hardware use and ensures that the device is
turned off after it has been used and that the status register is back

the value '1' in the related 'mutex', use 0xff which won't match any task.
