AP_InertialSensor: Flymaple filter constructor arguments non non-zero
AP_HAL_FLYMAPLE: Modest speed improvements to I2CDriver

Can now achieve about 285kHz using bitbanging.
Proper low-level hardware I2C support has been written and stashed,
but has to wait until a bug in libmaple is addressed.

AP_HAL_FLYMAPLE: Improvements to FLYMAPLEStorage

Fix a number of bugs and expand storage to an emulated 4kb, as needed by AP.
AP_HAL_FLYMAPLE: I2CDriver now uses low level hardware i2c librray from
libmaple

CAUTION: requires a patched version of libmaple, to be provided by mikem.
AP_HAL_FLYMAPLE: fix compile error in example AP_Baro_BMP085_test.pde

due to need for new library AP_Notify
AP_HAL_FLYMAPLE: Add test for correct version of libmaple

Patched version of libmapl is required for Flymaple I2Driver to work.
AP_InertialSensor: Improvements to Flymaple sensors

Fix a bug that caused hang after 71 minutes. Use I2CDriver semaphore.
Remove test for in_accumulate: not needed.
AP_HAL_FLYMAPLE: Fixed problem with tx buffer that caused slow parameter
delivery
AP_HAL_FLYMAPLE: update documentation in FlymaplePortingNotes.txt

Added info about where to get my patched version of libmaple.
