HAL_PX4: rewrite UART driver to be much more efficient
...
this does the IO in the timer thread, and uses buffers in the main
task to avoid system call costs in the flight code.
The cost of PX4 read and write system calls is quite high - about 10
to 15 usec. We can't afford to pay that per byte

HAL_PX4: switched scheduler to use a pthread
...
this allows the timer tasks to access file descriptors in the main APM
task, which makes writing PX4 device drivers much easier
