- uORB::SubscriptionBlocking is a specialized uORB::Subscription that allows you to do a blocking read
- this is intended to be an easy to use, hard to misuse replacement for the typical orb fd + poll pattern we've relied on historically
- landed, maybe_landed, or ground_contact required before the safety
button is able to disarm
- this reduces the risk of a faulty safety button triggering in regular
flight
- this is a new module for temperature compensation that consolidates the functionality previously handled in the sensors module (calculating runtime thermal corrections) and the events module (online thermal calibration)
- by collecting this functionality into a single module we can optionally disable it on systems where it's not used and save some flash (if disabled at build time) or memory (disabled at run time)

When having no velocity estimate the derivative was updated with zero.
When losing the velocity estimate this is fine since the resulting
derivative spike doesn't get used and acceleration is set to NAN.
But when regaining the velocity estimate the spike from zero to
the first estimated velocity gets used as acceleration in the position
controller and results in a twitch.
To solve this I use the derivative reset I introduced in pr #13522

This caused bad altitude control performance when enabling
terrain following. It even leads to complete vertical control
instability in case dist_bottom is inaccurate.
Relying on the estimator states is the way to go instead of
silently using one altitude source as state.
- split out integrated data into new standalone messages (sensor_accel_integrated and sensor_gyro_integrated)
- publish sensor_gyro at full rate and remove sensor_gyro_control
- limit sensor status publications to 10 Hz
- remove unused accel/gyro raw ADC fields
- add device IDs to sensor_bias and sensor_correction
- vehicle_angular_velocity/vehicle_acceleration: check device ids before using bias and corrections
- this provides some extra space when the FIFO transfers don't align perfectly
- I've also made an effort to keep the different drivers (icm20602, icm20608g, ism330ldc) in sync so we can factor out the common portions later once we've confident in the pattern.
* Treat UAVS diffrently from manned aviation
* Added fake_traffic testing functionality,
* Added NAV_TRAFF_AVOID Hold and Landmode
* Added Behavior: HOLD Position to collision avoidance mode and implemented Landmode to collision avoidance.
Boards where no Hardware GUID is defined will send 0 as GUID.
Right now collision avoidance for more than one FMU without Hardware GUID is not possible.
We should consider adding a randomly generated HW GUID as a placeholder for legacy Boards
The bulk of this change was tightly coupled and needed to be deleted in one pass. Some of the smaller changes were things that broke as a result of the initial purge and subsequently fixed by further eradicating unnecessary platform differences. Finally, I deleted any dead code I came across in the related files I touched while going through everything.
- DriverFramework (src/lib/DriverFramework submodule) completely removed
- added dspal submodule in qurt platform (was brought in via DriverFramework)
- all df wrapper drivers removed
- all boards using df wrapper drivers updated to use in tree equivalents
- unused empty arch/board.h on posix and qurt removed
- unused IOCTLs removed (pub block, priv, etc)
- Integrator delete methods only used from df wrapper drivers
- commander: sensor calibration use "NuttX version" everywhere for now
- sensors: update to px4_{open, read, close} instead of DevMgr wrapper (adc open for analog differential pressure)
- battery_status: update to px4_{open, read, close} instead of DevMgr wrapper (adc open for analog differential pressure)
- cdev cleanup conflicting typedefs and names with actual OS (pollevent_t, etc)
- load_mon and top remove from linux boards (unused)
- delete unused PX4_MAIN_FUNCTION
- delete unused getreg32 macro
- delete unused SIOCDEVPRIVATE define
- named each platform tasks consistently
- posix list_devices and list_topics removed (list_files now shows all virtual files)
