Instead of dragging around the weird CC1111 RSSI values, just compute
a dBm value in a signed 8-bit integer, ao_radio_rssi. Use that
everywhere we need RSSI internally. We leave the weird CC1111 value in
the packet reply as that's what the host expects.

getchar relies on interrupts being blocked across the pollchar calls
and into the sleep call or it may go to sleep with data pending.
This prefixes all pollchar functions with _ to indicate that they are
to be called with interrupts blocked and eliminates all interrupt
manipulation calls from within the pollchar functions.

AO_READ_AGAIN doesn't fit in a char anymore now that stdio is 8-bit
clean, everyone using pollchar must use an 'int' variable to capture
the whole value from pollchar.

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 adds a new 's' command to TeleDongle to report RSSI value from last
received packet, and then has AltosUI request that value when closing
the remote link.

This does "something" in radio test mode, appearing to generate a
730MHz signal.
