Enable Airspeed to be measured/reported, but not used for AP.

[GoogleCodeExporter]

Today we have two options; to use or not to use AS.
If airspeed is disabled, it is not displayed in Mission Planner, or can be 
displayed on OSD.

In order to enable better, more reliable AS tuning, testing, or just use it for 
OSD I wish one of two methods were in place:

IF AIRSPEED_SENSOR=Enabled (use airspeed for AP  (just as today))
IF AIRSPEED_SENSOR=Disabled (don't use airspeed for AP, but get it and provide 
over MAVlink)

or: If the above method have a drawback:

IF AIRSPEED_SENSOR=0 (don't use airspeed for AP, no AD)
IF AIRSPEED_SENSOR=1 (get and use airspeed for AP  (just as today))
IF AIRSPEED_SENSOR=2 (don't use airspeed for AP, but get it and provide over 
MAVlink) 

of course, to save variable space, we could have two bool values:
AIRSPEED_SENSOR (enabled/disabled)  (when enabled - the values are in MAVlink)
AIRSPEED_USE (enabled/disabled)  (AP would use it if enabled)
