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

After I got a compiler warning for a printf format in this file
(which I cannot reproduce anymore; for some reason g++ is usually
quite happy with all the errors in this file), I fixed all 'printf'
formats to match the type of their arguments as follows:

uint8_t         : %hhu
uint16_t        : %hu (or %hx)
uint32_t        : %u (or %x)
int16_t         : %hd
int and int32_t : %d
long int        : %ld

Since this file is C++, what we REALLY should be using is
ostream operator<<'s of course (type safe by design and faster
(compile time type matching, no need for format decoding)).

* Publishes LPE GPS epv and eph as estimator status.

* Adds timestamp

otherwise the battery estimator does not compute bat_v_empty_dynamic correctly

readdir_r is deprecated since glibc version 2.24 and glibc manual
recomends usage of readdir instead of readdir_r.
Replacing readdir_r by readdir will also not be a problem for Nuttx,
because readdir_r is using readdir and filling parameters with the
return information.

* Use sorted to fix python3 build error

* Add drv_hrt.h include to Bebop df wrappers

This will make the build works in distros that have Python 3 as default
and will not break anything in distros that have Python 2 as default.

This reverts commit 2a90f7e9.

MAVLink: Cleanup of port handling, switch to MAVLink 2 if receiving MAVLink 2. Announce MAVLink 2 capability in autopilot_version message

commit

Flight test went well, merging.
