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.

With multiple input source support, there is a lag between asking a
device if it has data and then waiting for more data to appear. If an
interrupt signalling additional input arrives in this interval, we'll
go to sleep with input available.
This patch uses a big hammer by just disabling interrupts for the
whole process.

This creates per-product subdirectories and recompiles everything for
each product, allowing per-product compile-time changes for things
like peripheral pin assignments and attached serial devices.

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
