Untested, but it 'should' work. Need to add callsign setting to packet
mode users.

Oh, right SDCC has '__critical' to mark sections of code that need to
run with interrupts disabled; no need to use EA = 0 and EA = 1.

To receive telemetry after disabling the packet system, the radio must
be reconfigured for telemetry mode.

Using the implicit stdio functions (putchar/getchar/flush) would
result in essentially random redirection of each, depending on whether
the packet code had characters available when getchar was called. This
would cause lockups in putchar.

This keeps the packet thread from blocking on USB and also makes the
flush happen after every packet (slightly more USB traffic, but
packets are slow anyway).

This splits the packet code into master/slave halves and hooks the
slave side up to the getchar/putchar/flush logic in ao_stdio.c
