Make some space on FMUv1
EKF filter update. Now correctly scaling variance (well, if you could call this ever "correct") for repeated fusion of the same data quantity.
Merge branch 'master' of github.com:PX4/Firmware into ekf_varweight
Add long-term stable wind estimate
Use the wind speed estimate filtered values
uavcan: increased thread prio, reduces roundtrip latency by a factor of 5..7
autolaunch: added param for delay
catapult launch detection: fix integration logic
Merge remote-tracking branch 'julian/launchdelay' into launchdetectionstates
launchdetector: return state of detection

The launchdetector now has a intermediate state (controlsenabled) which
is meant to be interpreted by the controller as: "perform attitude
control but do not yet power up the motor". This can be used in the
floating phase during a bungee launch for example.
fw pos control: use new lauchdetector states
fw pos control: set default roll, pitch while waiting for launch
fw pos control: launchdetection logic cleanup

Run full update straight after reset, filter wind speed dynamically
avoid changing the reset logic
