* For some reason cppcheck complains with `fp != nullptr` but accepts truthiness
of handle by itself.
* Note that the expressions are equivalent according to the C++ standard ("A
prvalue of arithmetic, unscoped enumeration, pointer, or pointer to member
type can be converted to a prvalue of type bool. A zero value, null pointer
value, or null member pointer value is converted to false; any other value is
converted to true. A prvalue of type std::nullptr_t can be converted to a
prvalue of type bool; the resulting value is false.")
1) Add hwtypecmp command to allow rc to further enumerate PX4FMU_V2
for sub types of 'V2' -FMUv2 'V2M' PixhawkMini, 'V30' Cube
2) Extend hw to report to display

HW version
HW revision
* update ecl to latest
* EKF2_GPS_DELAY change default 200ms -> 110ms
- 110msec is more representative of what most users are flying
* EKF2_ASP_DELAY change default 200ms -> 100ms
The EKF is relatively insensitive to airspeed sensor delays and the effective delay is installation specific, so it has been set to a value that does not cause the data buffers to be longer than is required to accomodate GPS delays.
Initialisation changes to address valgrind errors
Change to default GPS and Airspeed time delay (these are overwritten by ekf2_main parameter settings)
Increase sensitivity of bad accelerometer checks
Miscellaneous bug fixes and improvements including:
More conservative reporting of velocity and position accuracy when aiding is lost
Separate reporting of accuracy for local and global position
Detection and recovery from badly conditioned accel bias states and covariance values
Logic to prevent high manoeuvre levels causing bad acceleration bias learning
Reduce sensitivity of covariance prediction to timing jitter
Continue reporting of GPS quality until the later of airborne or checks pass
Add ability to perform wind estimation for multi-rotors using a specific force drag model
