Branch for MatrixPilot 4.0, 4.x
MatrixPilot 4.x: Cleanup, disable NORADIO
branch MatrixPilot_4_x: change mavlink baud rate default back to 57600
MatrixPilot_4_x branch: Changed repository source identification string in MPLAB-X projects. Added GPS_TYPE check to config_tests. Updated selected example-options-files.
MatrixPilot_4_x branch: Updated remaining example-options-files.
MatrixPilot_4_x branch: removed errant printf from gpsParseUBX, adding required define in OSD for UDB4/5 builds, and fixed inconsistent setting in example option file which caused an error report from config_checks.
Fix a use of RCON outside libUDB
Fix SILSIM building
branch MatrixPilot_4_x:  Take out a new additional 1000m*1000m T3 butterfly course that had appeared in waypoints.h and revert waypoints.h to it's normal default waypoints.
branch MatrixPilot_4_x:  Put warning back into magnetometerOptions.h to force user to set it up correctly when MAG_YAW selected in options.h
MatrixPilot_4_x: reverted MPU-6000 to using an 8 MHz SPI bus during data register reads so as not to be exceeding Microchip specifications (for dsPIC33EP device, am assuming dsPIC33F is similar however have not checked). dropped options_local.h include from the MPLAB-8 AUAV3 project.
MatrixPilot_4_x: Removed extra bracket from delay_us
MatrixPilot_4_x: Updated 16 MIPS init values to match the 667 kHz Init speed from the WJP branch. Also included the 32 and 64 MIPS 667 kHz scaled init values. All speeds were tested with an AUAV3. Updated the comments to reflect current settings.
MatrixPilot_4_x: change to address correct register when setting external interrupt priority for MPU-6000 on SPI2 option.
MatrixPilot_4_x: update comments on divisor ratios to be consistent with the code.
branch MatrixPilot_4_x: new MPLAB-X project MatrixPilot-udb5-v4x: builds correctly and stabilization works
branch MatrixPilot_4_x: new MPLAB-X project MatrixPilot-udb5-v4x: builds correctly and stabilization works
branch MatrixPilot_4_x: revert accidental change to options.h
branch MatrixPilot_4_x: update project udb5-mw options and waypoints
MatrixPilot_4_x: updated RollPitchYaw MPLAB-8 and X projects for UDB4/5 and AUAV3 boards. Fixed compile bug in MAVLink.c when ANALOG channels are defined.
branch MatrixPilot_4_x: project RollPitchYaw-udb5-v4x: fix red LED blink rate and change baud rate to 115.2K in main.c, fix project ref. to options.h
