This commit changes the BLE _IRQ_SCAN_RESULT data from:
addr_type, addr, connectable, rssi, adv_data
to:
addr_type, addr, adv_type, rssi, adv_data
This allows _IRQ_SCAN_RESULT to handle all scan result types (not just
connectable and non-connectable passive scans), and to distinguish between
them using adv_type which is an integer taking values 0x00-0x04 per the BT
specification.
This is a breaking change to the API, albeit a very minor one: the existing
connectable value was a boolean and True now becomes 0x00, False becomes
0x02.
Documentation is updated and a test added.
Fixes#5738.
This commit ensures that the BLE stack is active before allowing operations
that may otherwise crash if it's not active. It also clarifies the state
better (adding the "stopping" state) and renames mp_bluetooth_is_enabled to
the more self-explanatory mp_bluetooth_is_active.
