Add FrSky telemetry application.
This daemon emulates an FrSky sensor hub by periodically sending data packets to an attached FrSky receiver.
Merge branch 'master' into frsky_telemetry
Fixes to FrSky telemetry data formats.
Merge branch 'master' into frsky_telemetry
Update copyright info for 2014.
Happy New Year everyone!
Directly write to the voltage field for better precision.
Only send data packets we really support.
Further data format and code style fixes.
Merge pull request #578 from kroimon/frsky_telemetry

Add FrSky telemetry support
Added support for Octo Cox
attitude_estimator_ekf: acc compensation improvements
px4iofirmware: make forceupdate more reliable

this schedules a reboot rather than rebooting immediately, which means
the FMU gets an ACK for its reboot operation, preventing it from
timing out waiting for the ACK. That makes the timing of the reboot
more consistent, which makes it more reliable for forceupdate
FMUv2: make all UARTs use 512 byte buffer, 2048 for CDCACM output

this is important when using UARTs for things like secondary GPS
modules, which may produce large enough transfers that 128 bytes is
not enough.

The 2048 buffer for CDCACM transmit makes mavlink log and parameter
transfer faster
FMUv2: enable RXDMA on 2nd GPS port and debug console

This should reduce the chance of lost data on these ports due to high
interrupt latency
meas_airspeed: avoid trivial dependency on math lib

including the math lib adds a huge amount to flash usage
FMUv1: use larger CDCACM buffer size for faster log transfer on FMUv1
ms5611: report P and T in ms5611 info
px4io: enable power on Spektrum connector on init
mc_pos_control: bug fixed
