AP_Baro: more precise altitude calculation on PX4

if not using an AVR CPU then use a more computationally expensive
altitude calculation, which is more precise at higher altitudes

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.

Update floating point calculations to use floats instead of doubles.
...
- Allows use of hardware floating point on the Cortex-M4.
- Added "f" suffix to floating point literals.
- Call floating point versions of stdlib math functions.

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.

Baro: added get_altitude() and get_climb_rate() interfaces
...
this allows the barometer driver to calibrate and return altitude and
climb rate values. This will be used by the AHRS drift correction code
for vertical velocity
The climb rate uses a 5 point average filter
