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.
See related #7373.

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)
