- added lowest/highest_threat tracking. This is currently defined as 2D distance. Room for improvement to make it 3D and be flight vector based instead of distance
- when trying to add a vehicle but the buffer is full, overwrite the lowest_threat/furthest
- added basic THREAT enum of high/low which means in or our of the 200m radius. Room for improvement here.
Like was done for AP_HAL_Linux in 2ac96b9 ("AP_HAL_Linux: remove prefix
from AP_HAL_Linux classes"), remove the "Empty" prefix from class names
since we are already inside the Empty namespace.
This was previously used to allow to save a state in a SPIDriver so we
could synchronize the initialization of AP_Compass and
AP_InertialSensor.
It was only used by MPU9250 and is not used anymore since the move to
AuxiliaryBus initialization and it's not used anymore since c3dae6f
("AP_InertialSensor: MPU9250: Remove methods not used anymore")

This is the same approach as done for AP_HAL_Linux in e3d78b8 ("AP_HAL_Linux:
fix passing callback to member function"). It fixes the following warnings:

The argument in init() is not used by any implementation. Add a second
method without it so the HAL implementation can used it instead. Later
the unused method will be removed.
We don't need to expose to other libraries how each backend is
implemented. AP_Baro.h is the main header, included by other libraries.
Instead of including each backend in the main header, move them to where
they are needed. Additionally standardize the order and how we include
the headers.
The advantages are:
- Internals of each backend is not exposed outside of the
library
- Faster incremental builds since we don't need to recompile
whoever includes AP_Baro.h because a backend changed
The configuration of MS5637 is different from MS5611 in 2 ways:
- The PROM is of 112 bytes rather than 128
- The CRC is located in the first MSB of the first word, not the
last one
For CRC calculation we also need to zero out the last (missing) word.
This renames _check_crc() to _read_prom(), which returns false when the
PROM doesn't contain valid data. It also makes it virtual so MS5637 can
override it. This also moves the PROM read to be all in the same place
rather than split between the CRC field and coefficient fields. Finally
calculate_crc() is renamed to crc4() to be shorter and add info on what
it does.
On MS5637 we will need to override the method to read and calculate the
PROM's crc. Thus we need a 2-phase init.
It also makes the constructor of AP_Baro_MS56XX protected since only the
derived classes should instantiate the base one.
