The current code has the profile ref the device, but the device has no back-ref to
the profile. The following code will free the profile from underneath the
client, despite the caller still having a valid ref:
p = ratbag_device_get_profile_by_index(device, 0);
ratbag_profile_ref(p);
ratbag_device_unref(device);
Fix this by not using refs internally. After probe, the device is static
anyway, so the various refs internally aren't needed. Instead, we also ref/unref
the parent struct whenever we ref/unref a struct. Thus, whenevever the device
refcount reaches zero, we know the caller has no ref active.

Two components are added here: a test driver that takes a struct
ratbag_test_device and sets that device up as a ratbag device.
That device is returned to the tests and then checked for sanity.
The ratbag_device_new_test_device() requires the environment variable
RATBAG_TEST set, otherwise we abort. It's also 'hidden' in a separate source
file, so it won't show up in doxygen. And if the test are disabled, this
function does nothing and the test driver never gets registered.

Naming scheme is now:
* ratbag - the context
* ratbag_device - the device
* ratbag_profile
* ratbag_button
...
Only leftovers of "libratbag" are the header file name, #defines that are
exported through that header file and anything that has to do with the actual
library iself (e.g. the symbol export file).
