nRF CircuitPython boards will now provide the file transfer
service defined here: https://github.com/adafruit/Adafruit_CircuitPython_BLE_File_Transfer
USB capable boards will only advertise if previously bonded to a
device or if the reset button is pressed during the fast blue
flashes on start up. When pressed, the board will restart again but
the blue period will not flash.
Boards without USB will always advertise.
When previously bonded, the advertisement is private so that no
other peers can connect. If advertising publicly, the tx power is
lowered to reduce the likelihood of bonding from a distance.
This PR also fixes issues with loading identities of bonded peers
so that our address can now be resolved and we can resolve others'
addresses when scanning.
Add an optional 'lock' kwarg to callback that locks GC and scheduler. This
allows the callback to be invoked asynchronously in 'interrupt context',
for example as a signal handler.
Also add the 'cfun' member function to callback, that allows retrieving the
C callback function address. This is needed when the callback should be
set to a struct field.

Testing was done on an amd64 Debian Buster system using gcc-8.3 and these
settings:
CFLAGS += -g3 -Og -fsanitize=undefined
LDFLAGS += -fsanitize=undefined
The introduced TASK_PAIRHEAP macro's conditional (x ? &x->i : NULL)
assembles (under amd64 gcc 8.3 -Os) to the same as &x->i, since i is the
initial field of the struct. However, for the purposes of undefined
behavior analysis the conditional is needed.

It reschedules the BT HCI poll soft timer so that it is called exactly when
the next timer expires.

Instead of using systick the BT subsystem is now scheduled using a soft
timer. This means it is scheduled only when it is enabled.

And call mp_pairheap_init_node() in soft_timer_static_init() so that
reinsert can be called after static_init.

* so that excess files are not included in sdist, perform build down
in circuitpython-stubs
* This means we need to
* Remove the need-pypi check
* Copy a setup.py, README, and MANIFEST.in into the stubs build location
* Revamp how the overall `mypy --strict` check lists its inputs
* Add a new test that actually installing the stubs lets us do type
checking (tools/test-stubs.sh)
* Add a missing return type to a __init__ function (why was this not
an error under `mypy --strict`, I wonder)
