This is likely not true, so allow not to check the other conditions.
Also remove comment since this is going to be added to the method.

Global: remove mode line from headers

Using a global .dir-locals.el file is a better alternative than
reincluding the same emacs header in every file of the project.

AP_HAL: AP_HAL_Linux: add comment to I2CDevice::transfer()
...
If I2CDevice::transfer() has to do nothing it returns false. This can be
misleading, as this might feel contradictory.
Let's spend a comment on that.

AP_HAL: AP_HAL_Linux: perfect I2CDevice::transfer()
...
According to man 3 ioctl, ioctl returns other values than -1 on success.
So loop while ioctl returns -1.
Furthermore, there is no necessity to initialise r with -EINVAL,

This was there for compatibility with I2CDriver and SPIDriver. We don't
use them anymore so we can remove the compat method.

AP_HAL_Linux: implement function to transfer data

This is a similar function to what we have in I2CDriver, but it can
receive a nullptr to recv or send. It will create 2 i2c_msg structs to
send and receive data to/from the I2C slave.

These are very similar to their counterparts in I2CDriver. The changes
were:
- Don't use fixed buffer with PATH_MAX length: allocate the string
- Change the interface to use std::vector so we can simplify the
implementation
