Travis now limits the amount of free minutes for open-source projects, and
it does not provide enough for this project. So stop using it and instead
use on GitHub Actions.

Also known as L2CAP "connection oriented channels". This provides a
socket-like data transfer mechanism for BLE.
Currently only implemented for NimBLE on STM32 / Unix.

Hardware I2C implementations must provide a .init() protocol method if they
want to support reconfiguration. Otherwise the default is that i2c.init()
raises an OSError (currently the case for all ports).
mp_machine_soft_i2c_locals_dict is renamed to mp_machine_i2c_locals_dict to
match the generic SPI bindings.
Fixes issue #6623 (where calling .init() on a HW I2C would crash).

This fixes the build for non-STM32WB based boards when the NimBLE submodule
has not been fetched, and also allows STM32WB boards to build with BLE
disabled.

This is needed to moderate concurrent access to the internal flash, as
while an erase/write is in progress execution will stall on the wireless
core due to the bus being locked.
This implements Figure 10 from AN5289 Rev 3.

This commit switches the STM32WB HCI interface (between the two CPUs) to
require the use of MICROPY_PY_BLUETOOTH_USE_SYNC_EVENTS, and as a
consequence to require NimBLE. IPCC RX IRQs now schedule the NimBLE
handler to run via mp_sched_schedule.

This test currently passes on Unix/PYBD, but fails on WB55 because it lacks
synchronisation of the internal flash.

This changes stm32 from using PENDSV to run NimBLE to use the MicroPython
scheduler instead. This allows Python BLE callbacks to be invoked directly
(and therefore synchronously) rather than via the ringbuffer.
The NimBLE UART HCI and event processing now happens in a scheduled task
every 128ms. When RX IRQ idle events arrive, it will also schedule this
task to improve latency.
There is a similar change for the unix port where the background thread now
queues the scheduled task.

This requires that the event handlers are called from non-interrupt context
(i.e. the MicroPython scheduler).
This will allow the BLE stack (e.g. NimBLE) to run from the scheduler
rather than an IRQ like PENDSV, and therefore be able to invoke Python
callbacks directly/synchronously. This allows writing Python BLE handlers
for events that require immediate response such as _IRQ_READ_REQUEST (which
was previous a hard IRQ) and future events relating to pairing/bonding.

Using a semaphore (the previous approach) will only run the UART, whereas
for startup we need to also run the event queue.
This change makes it run the full scheduler hook.

Instead of having the stack indicate a "start", "data"..., "end", pass
through the data in one callback as an array of chunks of data.
This is because the upcoming non-ringbuffer modbluetooth implementation
cannot buffer the data in the ringbuffer and requires instead a single
callback with all the data, to pass to the Python callback.
