AP_Baro: add set_external_temperature()
...
this allows the use of an external temperature sensor for calibration
purposes, such as the sensor built in to the digital airspeed sensor.
The main affect this has is on the EAS2TAS calculation
The get_calibration_temperature() is used to choose either an external
temperature or an internal one. If an internal one is used then it is
clamped at no higher than 25 degrees C, to prevent hot electronics
on startup affecting altitude scaling and EAS2TAS

Add AVR compatibility header for missing math.h definitions.
...
- Define float versions of math functions to the double versions
on AVR (eg. #define sinf sin).
- These macros appear to be missing in older versions of avr-libs.
- Include AP_Math.h rather than math.h to get these definitions.

AP_Baro: improved barometer averaging
...
this changes the barometer calculations to floating point. On a MS5611
this is actually about twice as fast as the previous 64 bit
calculations, but gains us more accuracy as we are able to take
advantage of sub-bit precision when we average over 8 samples.

climb rate values. This will be used by the AHRS drift correction code
for vertical velocity
