removed retarded small_angles shit and replaced with proper calculation.
no more small angles while shaking the board.

added ability to assign one of aux1..4 channels as RSSI by the-kenny

actually adding BMA280 driver files, oops.

reorganization of uart-based receiver drivers
FEATURE_SPEKTRUM has been removed and replaced with FEATURE_SERIALRX.
cli  option serialrx_type now configures what type of receiver it is
0 = spektrum1024, 1 = spektrum2048, 2 = sbus
sbus will need hardware inverter to use.
also cleaned up receiver drivers to assign readrawRC callback instead of assigning in code in main()
none of this has been tested.

Totally rework software serial to provide tx at the same time as rx using only one timer.

First cut at polymorphic serial port implementation.  Split serialPort_t into uartPort_t and serialPort_t.  Calls to uartWrite() can now be replaced with calls to serialWrite().

Replacing calls to serialWriteByte(softSerial_t*, char) with calls to serialWrite(serialPort_t*, char).  This completes the proof of concept for polymorphic serial port implementations (uartPort and softSerialPort).

Renaming isSerialAvailable to uartTotalBytesWaiting.  Renaming serialAvailable to softSerialTotalBytesWaiting.  Adding serialTotalBytesWaiting to serial API and updating calls to the former methods to use the serial API.

Renaming serialRead to softSerialRead.  Adding serialRead to serial API and updating calls to uartRead and softSerialRead to use the serial API.  Renamed uartPrint to serialPrint which now works on any serialPort implementation.

Replacing calls to isUartTransmitEmpty with isSoftSerialTransmitBufferEmpty.  Replacing remaing calls to uartWrite with serialWrite.  Adding isSoftSerialTransmitBufferEmpty to the serial API.  Adding serialSet/GetBaudRate to the serial API.  Since softSerial does not implement serialSetBaudRate some GPS serial initialisation code has been updated.

At this point it is probably possible to switch around all the ports and use a software serial implementation if desired.

some whitespace and formatting cleanups on the last commit.
also changed GPIO_GetInputDataBit to use proper digitalIn() api

calculate heading using gyro-only on boards without mag - idea by Cesco
added constants for gyro/acc/baro cal and fixed calibration to add /2
warning cleanup in drv_serial.c

fixed a fuckup with yaw_rate that was caused by more 8bit leftover garbage
fixed althold vel/constrain typo thx Marcin
flight-tested this build on my shitcopter, CAREFUL flight testing may commence.

fixed buzzer on rev5 boards;
added experimental gyro-based headfree boxes

personal debug changes

6 32 bit vars can be used for debug now
added option to disable setting motors to minthrottle

that way the copter still stabilizes it's self when throttle is at
minimum
old altitude calculation is used again

changed to the old altitude calculation, seems less error prone and more
stable.
also added some proper float to int conversions instead of autocasting
testing some stuff

mma8452 full scale used now and full scale set to 2G
preliminary draft of a new pid using actual values added
