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.
PWM6+7/TIM3_CH3+4/PB0+PB1
Update software serial to monitor serial pins for signal changes instead
of periodically sampling pin signals.
When reading the data the timer used is syncronized to the falling edge
of the start bit which allows for better syncronisation at higher
speeds. The code has been tested OK from 1200 baud to 19200. 38400
baud was tested and partially usable but has been disabled because there
are too many transmit and receive errors, especially when transmitting
and receiving at the same time.
Due to the way a single timer is used for transmitting and receiving, if
data comes in while transmitting the system may incorrectly transmit a
short or long bit. However at 19200 and below this didn't cause a
problem in the limited testing I performed.
set motor_pwm_rate to some value > 500 (1000, 8000, 16000 etc works on my scope).
then the motor output can be used to directly drive brushed motor fets.
PWM is rescaled to 0-base in brushed mode, so all same values of min/maxthrottle apply.
* Proper initialization sequence framework for various supported GPS types. NMEA will now auto-detect its baud rate based on received frames.
* As a result of the above, gps_baudrate has been changed to enum, to only allow fixed rates. (GPS baudrate, -1: autodetect (NMEA only), 0: 115200, 1: 57600, 2: 38400, 3: 19200, 4: 9600)
* UBX binary initialization at any specified baudrate with auto-reconnect on signal loss.
* GPS thread to handle initialization, signal loss and configuration. No longer does GPS need to be powered before FC, and on GPS reconnect, it will be re-initialized if needed.
MTK NMEA/binary initialization is omitted for now, as I can't find my MTK GPS
GPS deltaTime can be calculated to display update rate.

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.

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.

added and began work on integrating failsafe_detect_threshold
got rid of acc_lpf_for_velocity since that seemed no longer used.

PWM and ADC configuration is the same as the naze32 for now. Requires an accelerometer is connected via I2C2.
I2C signals SDA2 and SCL2 are on the UEXT header (Pins 6 and 5 respectively)
USART signals TX and RX are on the CON3/CON4 headers (TX = D7, RX = D8)
Onboard LEDs (LED1/LED2) working.
Buzzer support removed for now as it conflicted with PWM map and LEDs.
mma845x support disabled as it conflicted with an LED.
Relocated some NAZE specific comments.

mw2.2-merged stuff:
* implemented profiles 0-2 (called 'setting' in mwiigui)
* merged in MSP changes including profile switch
* cleaned up rc / aux switch stuff in mw.c based on 2.2 rewrite
* main loop switch for baro/sonar shit adjusted
todo: basically the rest of 2.2 changes (i think some minor imu/gps/baro updates)
baseflight-specific stuff:
* made boxitems transmission dynamic, based on enabled features. no more GPS / camstab trash if it's not enabled
* cleaned up gyro drivers to return scale factor to imu code
* set gyro_lpf now controls every supported gyro - not all take same values, see driver files for allowed ranges, in case of invalid lpf, defaults to something reasonable (around 30-40hz)
maybe couple other things I forgot. this is all 100% experimental, untested, and not even flown. thats why there's no hex.
merge is still ongoing.

fixed pwm init for airplane mode mistakenly deleting motors from the mix. flyingwing should really work now.
removed led debug from althold

I heard thats not a problem since tarduino only allows 4RC+2AUX channels anyway! If you want more, upgrade to PPM.
So you use RC3/4 for GPS, and connect the rest of the channels as usual. Channels used for GPS uart are
skipped, so no changes to 'map' are necessary. Simply connect in order.

synced angle/horizon mode stuff from mwc. no idea what it does.
perhaps the most important part of this update:
-errorAngle = constrain(2 * rcCommand[axis] - GPS_angle[axis], -500, +500) - angle[axis] + cfg.angleTrim[axis];
+errorAngle = constrain(2 * rcCommand[axis] + GPS_angle[axis], -500, +500) - angle[axis] + cfg.angleTrim[axis];
(which means GPS might actually work).

added ms5611 driver
refactored pressure sensor subsystem to allow multiple sensors
couple changes in PWM driver to make motor/servo arrangement for airplane mode more intuitive
moved MAX_MOTORS/MAX_SERVOS etc into drv_pwm.h
staring to merge back in airplane/flyingwing mixes
fix for tri servo display - mwc moved it to servo[5] again, gui was broken, function not.
will probably implement custom mixer soon (motors only, no servos)

this has been hover-tested.
all current functionality *should* work even though the driver has been rewritten.
please test carefully, especially servo configurations!

removed camtrig stuff since it wasnt possible. somewhat replaced with aux forwarding (see below)
2.1 buzzer code changed, untested.
removed flying wing mixer. nobody used that.
added alt_hold_throttle_neutral, nav_slew_rate and looptime configuration to cli. default looptime set to 3000. changed default gyro_cmpf to 400 to sync with 2.1.
increased bmp085 oversampling
added gimbal_flags (bit 4 set) flag which, in PPM mode, forwards AUX1..4 to the lower 4 PWM outputs instead of using them as motors. set gimbal_flags=8 to test it out. output is fixed to 50Hz.
merged 2.1 gps changes (not many)
casting in gyro smoothing (nobody uses that anyway)
calibrate accel in gimbal mode, set smallangle in gyro-only mode
vtail4 mixer fix
flight tested on quadx w/ppm.
