The existing implementation has about 100ms difference to a reference clock. With the changes this error less than 25us.
- Use sensor_gps messages with hrt timestamps as RTC reference and not the system realtime clock. The PPS interrupt can then be aligned with the GPS clock system.
- Keep fallback based on system RTC when no PPS pulse was captured
- camera_trigger module always publishes the camera_trigger msg (independent of the camera feedback)
- Use camera_trigger msg and set the feedback flag
- Subscribing modules determine if the message is relevant based on the feedback message
When using an FMU channel as PPS capture GPIO, the rtc_edge_time is now set as well. The delay between actual capture and callback is compensated with the elapsed time of the rtc clock.
- this was necessary to get the secondary ms5611 working reliably on a
particular CubeOrange
- the sensor is transferring very little data, so lowering the speed by
default everywhere is harmless
Use the same memory allocation in sw_crypto driver as what is used in
src/lib/crypto libraries
In addition, in nuttx protected build, allocate all memory from kernel heap

This fixes the following compile error on Mac:
src/drivers/gps/gps.cpp:562:23: fatal error: use of undeclared identifier 'B921600'
case 921600: speed = B921600; break;
^
It is possible to either set the keyfile locations in board configuration or
with the same environment variables as before.

This is more logical place for the "backend" implementation than
directly under platform.
This also allows making other implementations as "real" drivers, as well as proper configuration via Kconfigs

- 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
