This adds the env option PX4_FUZZ which runs the LLVM libFuzzer which
throws random bytes at mavlink_receiver using MAVLink messages over UDP.
The MAVLink messages that are being sent are valid, so the CRC is
calculated but the payload and msgid, etc. are generally garbage, unless
the fuzzing gets a msgid right by chance.
As I understand it, libFuzzer watches the test coverage and will try to
execute as much of the code as possible.
There was an error that PX4_CRYPTO was cached accross variants, if it was
defined just for one variant.
This synchronizes the caching of BOARD_CRYPTO with other similar BOARD_ flags;
it is set as INTERNAL and "1" when enabled.
Also remove handling of BOARD_KEYSTORE; it is not used anywhere after
changing the crypto under src/drivers. If a separate keystore driver
is required, it is just selected as any other driver in px4board

- cmake NuttX build wrapper compile in place instead of copying source tree to build directory
- slightly faster skipping necessary copying (depending on system)
- allows debugging in place
- easier to work directly in NuttX following official documentation
- simplifies overall build which should make it easier to resolve any remaining NuttX dependency issues in the build system
- the downside is switching back and forth between different builds always require rebuilding NuttX, but I think this is worth the improved developer experience
- also no longer builds px4io and bootloader in every single build, for most users these rarely change and we're wasting a lot of build time
- mavlink/mavlink is now directly included as a submodule instead of the generated mavlink/c_library_v2
- this also switches to mavlink development.xml by default
- 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
