Update software serial to support RX, TX or RX&TX modes. Update serial
API to allow on-the-fly changing of serial port mode. Update HoTT to
change serial port mode when transmitting.
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.

status in cli now prints cpu MHz, 72 when running off crystal, 64 when running off intrc.
corrected WHO_AM_I check for mpu6050 when it's used on alternate address (AD0 high).
corrected PWM driver to consider CPU clock for timer prescalers - now things properly work below 72MHz
added a neat hack for pitch angle calculation so that it's not affected when roll reaches 90deg
added proper math for vector rotation instead of small-angle approximation

use set gps_type=X in cli to configure, where X=0 if NMEA (no special config), X=1 if UBX (enters ubx binary mode), X=2 if MTK (sets up MTK for 5Hz operation).
changed default GPS rate to 115200 baud
added baudrate reset stuff to UART driver for GPS autoconfigure
NONE of this is tested (except UBX working on my window)

added interrupt pins from mag/mma/mpu for rev4 hardware. nothing done with them yet - candidates for EXTI use
added tx buffer to UART2 (gps) in preparation for auto-config

increased i2c send buffer to 16bytes (was needed for DMP)
decreased interrupt priority of both uarts - with GPS running at 115200, this would cause I2C errors (i2c interrupt must be highest priority).
GPS was tested with $25 FMP04 GPS module ghettoed up outside my window, locking 5 satellites in a few minutes.

removed feature digital_servo since its now set by cli instead.
added proper tx end check into uart, to remove delay inside printing out set values and tx buffer overrun during help()
instead of passing a bunch of params to pwm driver, made a config struct
fixed a bug in gps baudrate
fixed typo in stmloader.c
whitespace / indentation cleanups in various drivers
git-svn-id: https://afrodevices.googlecode.com/svn/trunk/baseflight@137 7c89a4a9-59b9-e629-4cfe-3a2d53b20e61
split uart2 initialization inside drv_uart. added receive data callback to use either with GPS or spektrum satellite
added spektrum satellite support, also freeing up 4 motor outputs for hexa/octo/camstab
configurable acc lpf and gyro lpf via cli
configurable (build-time) temperature lpf on baro. seems mostly useless.
fixed a nice boner bug in mag code which ended up multiplying magADC twice with magCal data.
fixed mpu3050 driver to allow configurable lpf, also broke other stuff in the process. considering moving this sort of stuff to "init" struct for sensor.
pwm driver rewritten to fully disable pwm/ppm inputs (such as using spektrum satellite case)
cleaned up double math in gps.c to use sinf/cosf etc
removed TRUSTED_ACCZ since its useless anyway
whitespace cleanup
