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

AP_Baro - removed unnecessary 2 element average filtering of pressure (there is a 4 or 5 element average filter in arducopter code itself, two places is messy)
...
- also removed unused _offset_press variable

AP_Baro - added average filter for temperature to replace broken filter
...
- added average filter (for last two values) for raw pressure
- changed some "long" to int32_t and "unsigned long" to uint32_t

Updated on Barometer - increased the Temp filtering and decreased the pressure filtering to and get less temp noise, faster response from pressure. I'm filtering the Climb rate differently now, so this higher pressure noise should not hurt the derivative calcs at all now.

baro: fixed an integer overflow issue at high altitudes
...
the averaging array was using 16 bit numbers, but we are storing
numbers with 19 significant bits. That caused overflow at high
altitude, and some very interesting altitude graphs!
Thanks to Michael Oborne for spotting this in a log
