f1edd1bafb GCS_MAVLink: removed use of mavlink_check_target() 
not needed now we do routing properly, as messages will only be
processed if they are for us

193bda068c HAL_Linux: run IO processes when we do a stop_clock() 
this has the effect of allowing logging to progress in Replay where we
are running at much more than realtime speeds

cb9c518ab8 Revert "AP_NavEKF : Reduce ripple in estimates that can cause copter motor 'pulsing'" 
This reverts commit 13df6fb1c9.

This patch was a result of an incorrect merge of the optflow branch
into master. It reintroduced the bug fixed by this commit:

12ea1d6e85 AC_AttitudeControl: Scale angle demand noise filter 
Scales filter frequency using EKF nav gain scaler to take advantage of the reduced nav frequency whichcan tolerate a slower angle response.
This is required to reduce the effect of EKF optical flow noise increase with height.

5532750a99 AP_AHRS: Add public method to inhibit GPS useage when using EKF 
This provides the calling vehicle software the abiity to request the EKF to not use GPS.
An integer is returned that indicates the type of operation available:
0 = request rejected (request will only be accepted if the EKF is in static mode, eg pre-armed)
1 = request accepted, attitude, vertical velocity and position estimates available
2 = request accepted, attitude, height rate, height, horizontal velocity and relative position estimates available

1f78a73cdb AP_NavEKF: Make flow measurement delay vehicle specific 
This takes into account the inter-sampling delay between the flow driver and the APM software which depends on the rate at which the dirver is being checked. This is 50Hz for plane and rover, and 200Hz for Copter.
