HAL_PX4: switch to delay_microseconds_semaphore() for UART timer
...
this may prevent some timing jitter on the GPS UARTs

HAL_PX4: prevent threads running before subsystems are initialised
...
this fixes a bug where the timer thread would hang waiting for the
console on startup. This caused the "hit enter" behaviour with recent
PX4 bugs, as AnalogIn tried to read from fd==0, which was a console
read

HAL_PX4: fixed a scheduler bug that affects UART IO
...
we need to detect if we are in a timer task using a PID, not a
flag. This is the same type of bug I fixed last week, but now fixed
properly.
The bug could well be the "USB bug" that Craig has been chasing

HAL_PX4: use hrt timer and semaphores to improve timing
...
this gives much more accurate microsecond delays, while also ensuring
we yield the CPU when possible

HAL_PX4: disable checks for in_timerprocess

these are not valid in this form for the way the timer thread works on
PX4.

HAL_PX4: new buffered storeage driver for microsd cards
...
this does all IO in the timer thread, avoids writes that don't change
data, and does all writes in multiples of 128 byte chunks. This should
be about as friendly to SD cards as we can get.

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
