fe964fcda0 PID: change to float input/output
this makes the PID library a bit more flexible for smaller range
numbers. Note that this library is used on ArduPlane and Rover, not

4800c57fb4 Fixed cosmetic typo in user display message
Corrected "it's" to "its". Just one of those grammar things that drives me crazy ;-)

7b1245937c AP_InertialSensor: always sample at 200Hz in MPU6000
this changes the sampling to 200Hz regardless of requested rate, and
it is downsampled inside num_samples_available() using a shift. This
gives better noise resistance in ArduPlane.

This patch also makes it possible to update the filter frequency while
running, which is very useful for bench testing with a vibration

c5f19f5df8 Plane: Implement issue 80: counterclockwise loiter
- libraries/AP_Common/AP_Common.h: Use bit 2 of Location.options to store
  loiter direction
- ArduPlane/defines.h: New bitmask MASK_OPTIONS_LOITER_DIRECTION for struct
  Location bit 2
- ArduPlane/ArduPlane.pde: New variable loiter_direction
- ArduPlane/GCS_Mavlink.pde: For mavlink loiter-commands use sign of param3 to
  detemine direction. Set Location.option flag accordingly
- ArduPlane/commands.pde: Make sure loiter-directions get saved into EEPROM
  correctly
- ArduPlane/commands_logic.pde: Set loiter_direction on all loiter-actions
  as well as RTL/instant loiter
- ArduPlane/navigation.pde: Yield loiter_direction in update_loiter

db8da71f65 Revert "AP_HAL_AVR: Improved AVRTimer micros() and millis()"
This reverts commit 527dcdf3b9.

This was causing the MPU6000 startup code to fail, due to time running
backwards.

527dcdf3b9 AP_HAL_AVR: Improved AVRTimer micros() and millis()
- More efficient code by using 16-bit timer
- micros() now has proper 1 us resolution and less overhead
- millis() has less overhead
- removed unneeded/unwanted initializatin of timers in AVRTimer::init()

952df2fced HAL_PX4: new buffered storeage driver for microsd cards
this does all IO in the timer thread, avoids writes that don't change
data, and does all writes in multiples of 128 byte chunks. This should
be about as friendly to SD cards as we can get.

6ffa18fa61 HAL_PX4: rewrite UART driver to be much more efficient
this does the IO in the timer thread, and uses buffers in the main
task to avoid system call costs in the flight code.

The cost of PX4 read and write system calls is quite high - about 10
to 15 usec. We can't afford to pay that per byte

18cfd29f2f HAL_PX4: added a read buffer to the UART driver
