Randy Mackay 46d65150af Copter: lengthen loiter stopping point 
This will make stops less aggressive when entering loiter at very high
speeds (more 7.5m/s)

Randy Mackay 400c1bd7b7 Copter: smooth waypoint transitions 
Speed of intermediate point is initialised and constrained based on
current speed vector vs direction to the next waypoint.
This means the copter does not slow if the previous segment and next
segment are in line and also the intermediate point is not advanced
towards the next waypoint if the copter is moving quickly in the
opposite direction.

Andrew Tridgell ba83950fc4 libraries: replace constrain() with constrain_float() 
this makes the type much more obvious. Thanks to Tobias for the
suggestion.
