This prevents accidental misconfiguration via I2C if there are
multiple SPI devices on the same bus. The device may hear it's i2c address
and write some register, while there is data transfer ongoing with another
device.

WorkItemSingleShot::_sem is a signaling semaphore, disable PI for it.
Set CONFIG_DEBUG_ASSERTIONS=y and the kernel panics due to the semaphore
having no holder, disabling PI fixes this.
The head/tail semaphores are not used as lock but rather as resource
counters and thus relate more as signaling semaphores. Disable PI for
them.
I run my code with CONFIG_DEBUG_ASSERTIONS=y and the kernel panics due
to the semaphore having no holder, disabling PI fixes this.
This prevents the mavlink transmit loop from waiting on the module mutex
thus not stopping transmissions when the mutex is already taken.
This can happen when calling `mavlink status` from the mavlink shell,
where `Mavlink::get_status_all_instances()` takes the mutex and then
prints the status via pipes to the mavlink transmit buffer.
If that pipe cannot be emptied a deadlock happens.
Since the MavlinkReceiver thread also waits on the module mutex, both
reception and transmission of Mavlink packets are then prevented thus
disabling communications entirely.
IMUs were replaced in V3 with 2x ICM42688P. This configuration should
work with all revisions of Matek F743 Slim board, including V1, V1.5
and interim variant of V3 (ICM42688P + ICM42605).

In the lightware_parser function, LW_PARSE_STATE2_GOT_DIGIT0 state can be repeated unexpectedly without proper parserbuf_index or state checking. This behavior will trigger a heap buffer overflow vulnerability by allowing to write some data. And the writable size is sizeof(unsigned).
* ekf2_derivation: use single source of state definition
The state is defined as an ordered dictionary of group elements and
everything else is generated using that state definition
* ekf2: generated state sample add const reference getter

The length check for unknown packets did not include PACKET_SIZE_TYPE_SIZE
and CRC_SIZE, and hence working_index could overflow CRSF_MAX_PACKET_LEN,
triggering invalid memory access further down in QueueBuffer_PeekBuffer.
Also the working_segment_size was wrong for unknown packets.

This allows to inject an updated ext_autostart folder with the name
ext_autostart_new, and then PX4 takes care of renaming it to
ext_autostart during bootup.

The sparse vector template requires to know which states are non-zero in
the observation jacobian. This complicates the modularity of the code
when the state vector or the derivation is changed.
The computation cost difference is almost negligible for this size.
For FW takeoffs we need to keep the course straight towards the first
waypoint, and not climb in loiter patterns first.
