A negative error means a communication error, while a positive one means
a HID++ one. Make sure we abort early enough.

rc is set to 0 by ratbag_open_hidraw_node(), and if matched failed, we
close the hidraw node and end the loop.

Once we start probing devices for multiple drivers we shouldn't just print
error messages for every failed driver. In the hidpp20 case an error would be
printed for any hidpp10 logitech device.

If a device is not specifically assigned a driver, try hidpp20 and then
hidpp10 hoping that one of them will work.

Prep work for being able to probe multiple drivers on a device. The function
that tests the actual driver simply takes a const char * with the driver name,
so in the future we can loop through multiple driver names easily.

No need for two separate cleanup blocks, they're doing the same thing anyway.
Just make the function more robust to uninitalized fields and we're good to
go.

hidpp10 devices have their own driver, let's not initialize them here and just
fail. If a hidpp10 device is assigned the hidpp20 driver this is a bug.

No reason for the drivers to have their own printf each, just return the
negative errno and let the common code print it.
This now also means that we only return -ENODEV on something that's not really
an error, for anything else we print the strerror.

We now get an error message for all devices that have duplicate event nodes
because we use -ENODEV for 'device not found', 'device is a duplicates' and
'device doesn't have the hidraw report'.
The original commit was triggered by a misunderstanding of the error message,
will be fixed in a follow-up.
This reverts commit 855a6bd831.

commit b3237fd0 ("lur: change new_from_hidraw to return an errno") broke
the API, so we need to bump the version too.

Otherwise, as soon as we set an action for a button, we get a nice

The previous API was inconsistent and different to the rest of libratbag's
API. Replace with one where a macro is a separate struct, can be initialized
and then written to the device with a set_macro() call. The device copies the
contents, the macro is otherwise unmodified and can be re-used by the client
if need be.

We don't do anything with the return value anyway and we do assign the driver
in this function. Rename it and return a boolean only.

Whenever we do something that may fail, return an enum of possible errors.
This also changes the API for ratbag_device_new_from_udev_device() to return
an error code now too instead of just NULL on failure.
Error numbers start at -1000 to avoid overlap with errnos, error_code() should
be used internally to avoid returning an errno.

Let the caller check that what they're passing in is correct, we don't have to
respond with sensible error codes here.

Designates a device that can be queried for the current configuration. Some
devices lack this ability so we rely on the caller to upload a known
configuration to the device before we can really proceed.
Set by default, devices without that capability should be the exception, not
the norm.
This patch just adds the capability, actual handling for this needs to be
added when we add the first device without this capability.
