MavLink spec implementation

implemented vehicle_roi topic

rename old gimbal to rc_gimbal

little changes

corrected RC Gimbal group

Starting ROI implementation in commander

implementation done, needs to be tested

uhm..

add todo

Change to float32 for x,y and z

remove mission topic again, not needed

change roi coordinates to lat, lon and alt

adjust to float64

starting mount implementation

correcting small mistakes, compiles now

add todos

further progress

implementing parameters

adjust default parameters

started implementation of mavlink

fix typo

change to lat, lon and alt

fix typo :D

change to double (to represent float64)

add global_position_

add mount topic

commander mount implementation done

cleanup

almost finished

little fix

codestyle fixes

leave pitch at 0 degrees

added pitch calculation

codestyle changes

Undo vehicle_mount, react to updated parameters, parsing of CMD_DO_MOUNT_* in mount.cpp

start implementing mode override

forgot a semikolon.

add debug

Finish implementation of mount override and manual control.

fix codestyle

correct cleanup

rename to vmount

works now

fix rebase error

fix polling

refactoring and custom airframe for gimbal

couple changes

remove warnx

almost done

finally

What is going on?

change back to actuator_controls_2

working

bump parameter version number and some clarification

fix submodules

Fix build error

Capitalization mistake for headers

Non-Mac compiler issue

Baudrate for crazyflie nrf and fix code style

Save space

Cleanup mpu9250 driver

Fixes for other boards

Functioning sensors

Working crazyflie firmware build

* Console on USART3
* Could not disable building PX4IO firmware, currently commented out

Don't build PX4IO firmware if the board doesn't ask for it

Added crazyflie motor driver

Fixed wrong register

CLK_SEL is in PWR_MGMT_1

Initial I2C/SPI MPU9250 device

* Tested with I2C
* Need to add error checking
* Intermittent crash on stop call

Working ak8963 mag driver

Functional lps25h driver. Work in progress.

Works well enough to probe and allow sensors task to start.

Added serial port test module

HACK! Get sensors module working

Set crazyflie PWM range

Extend baudrate for Crazyflie's NRF radio

Added dummy tone alarm to allow for init

Added autostart script for Crazyflie

this lets a user select what msgs should be compiled for his project
Care must be taken though, to compile all orb_topcis that are required by the Rest of the Code.
Otherwise many compile errors will occur.

This commits adds by default the ./msg include path to reference to other msgs.
if an exisiting msg is used in another msg.

* Path cleanup for SITL.

* Restructured sitl scripts dir.

* Set integration tests to use ekf2 for vtol.

* Fix sitl paths for mac.

* Low impact changes from path_cleanup branch.

This is a step towards minimizing the diff with path_cleanup branch.

* Update ecl.

* Revert matrix update.

* Revert ecl and matrix.

* Update sitl gazebo.

* Revert sitl_gazebo and matrix changes.

This reverts commit 699b6a2c.
