altos/stmf0: Fix external interrupts
Missing a reserved address in the registers broke everything nicely,
but the priority values were also wrong - stm32f0 exposes 8 bits per
priority, like the stm32l, but it uses only the top two bits.

altos/telelcotwo: Add idle timeout
Puts TeleLCOTwo in a low power state (drawing about 80µA) after a
timeout (default two minutes) to keep from killing the battery if the
device is left turned on.

altos: Use simpler debounce logic for buttons
Instead of waiting for a while after the transition to decide if it
has stuck, signal the event right away and then ignore other
transitions for the debounce interval.
This seems to work just as reliably, but has the benefit of
eliminating button latency at press time.
The LCO interface is likely to end up very device specific as the
interactions depends on the input devices. Here's a version for
TeleLCOTwo, which has two arming switches and a firing button.

altos: Allow for pad boxes with different sensor configurations
This allows for a pad box without a resistor from power to each

solid-state system, that's not a possibility.

Makes the voltage divider values configurable, and allows for pyro
channels that don't have the resistors necessary to check for a stuck
relay.
Also supports STM32L processors with wider GPIO registers, and uses
the new ao_gpio_set/clr_bits functions to fire igniters rather than
cc1111-specific code.

altos/stm: Validate current task SP in interrupt by looking at PSP
We use a separate stack pointer for task code, which means we can
verify that it is in range in any interrupt handler. This adds checks
for the task stack (under #ifdef DEBUG) that run in ao_wakeup as well
as at every timer interrupt.

altos: Fixed timing of panic display LED to be readable
When we don't have a beeper, there's no way to signal a 'warble' for
panic. So, elide that bit.
Second, panic can't use the scheduler and timer because those may not
be running (or may have failed), and so it uses a delay loop. Add a
configurable scale value to the panic loop so that the LED blinks can
be read. For stm32f0 devices, scale that by the sysclk value to
automatically make them of reasonable length.

This replaces having the single output switch based on a pin value and

pull bits as I haven't figure out how to make linux provide two
