sdcc offers __critical as a machine-independent way to block
interrupts, but as gcc doesn't, we need to use a compiler-independent
construct instead. ao_arch_critical has been around since the AVR
port, but some old __critical usages remained.
This fixes a bunch of random hangs when communicating with MM over USB
or the radio as the various stdio loops were running without
interrupts blocked between the test and the sleep.

This lets the cc1111 use the atomic bit operation instead of a mask,
which is immune to interrupt issues as well as being a shorter code sequence.

Blocking igniters on the radio mutex fails when doing igniter testing
over the RF link; the packet receiver task will never release the
mutex and the CPU at the same time, causing the system to lock up.

If you're in idle mode, you stop forever as the packet mode receiver
will own the radio mutex forever.
