SDLOG_ALGORITHM for selecting the crypto algorithm
SDLOG_KEY for selecting the key in keystore to use with the algorithm.
for symmetric algorithms which are currently supported, this is just a free
slot to be used, the key is generated at logging start
SDLOG_EXCH_KEY for selecting an RSA2048 key for encrypting the SDLOG_KEY

- Generate a symmetric encryption key and a nonce value
- Use a public key in keystore to encrypt the symmteric key
- Write the encrypted key and the nonce value to disk into .ulgk, name matching with the encrypted log file
- use quick stream encryption to crypt the .ulg file contents

There's an increasing amount of slow logged topics at 1-2Hz, which were all
updated in the same logger iteration, leading to data bursts. For log
streaming this started to exceed uart buffer sizes. By distributing updates
more equal over time those bursts are removed, reducing buffer size
requirements.
Tests showed during steady state a reduction of maximum topic updates per
iteration from 40 down to 17.
Also the SD log buffer fill level is more constant.
- naming consistency (estimator prefix as "namespace")
- only publish if baro is available and bias is changing as a small logging optimization
- avoid unnecessary copying (get const reference to status directly)
- trivial code style fixes
- sending protocol
- uorb event message & template methods for argument packing
- libevents submodule to send common events and handle json files
- cmake maintains a list of all (PX4) source files for the current build
(PX4 modules + libs), which is used to extract event metadata and
generate a json file
- adds new ulog message & compatibility flag
- separately add airframe and system-wide defaults
- log only non-volatile defaults that are different from the current value
- additional size is ~3KB for 100 params
* msg: Add estinator information and warning events message (estimator_event_flags)
* ekf2: publish information and warning events
* logger: log estimator_event_flags
* update ecl submodule to latest

- publish wind estimate only from EKF, and wind speeds from airspeed selector to new separate topic (airspeed_wind)
- rename message wind_estimate to wind
- publish wind from currently used ekf instance (ekf2selector)

- new heater_status logging message
- run continously at low rate until configured sensor is found
- fix px4io fd bugs (fd open/close/ioctl must be same thread)
- currently the main change is that it reduces the max number of ORB multi instances to 4, but usage will be expanded as needed
- limits number of EKF2 multi instances to 2.
- enabled on all cortex m4 boards
- control allocation module with multirotor, VTOL standard, and tiltrotor support
- angular_velocity_controller
- See https://github.com/PX4/PX4-Autopilot/pull/13351 for details
