For supported devices this can get and set the led colors in RGB.
This patch just adds the support in the lib. Later patches will
add it to the driver and expose it in libratbag.
On the M705 I frequently get usb timeouts here if the device has
not been active for a while. Retrying after 10 ms seems to reliably
fix the timeout problem.
We could have just added the 10 ms sleep directly but it does not
seem to be neccesary on wired devices so I chose not to. Setting the
ret value to a face positive number and looping would also work but
we risk an endless loop. In the end I just went for a single retry
as that fixed the problem for me.
This caused a problem since the hidpp10_device would keep a ref to
the ratbag_device - and the hidpp10_device would only get destroyed
when the ratbag_device got a ref count 0.
We do not check dev for null in any of the other functions. If it
was actually null then we would also already have got a null pointer
dereference earlier in the function.
The kernel overwrites the device ID with the correct one for our device, so we
can just use 0x00 for all devices and skip the search for the unifying
receiver hidraw device.
Since we're not talking to the receiver anymore, we can/have to drop the
pairing information queries and the related info. Since we weren't using this
anyway it's not a big loss.

HID++ 1.0 doesn't have an index of functions available, so we pretty much
have to bang every request against the device, full of hope and optimism.
Reality demands that some of them fail and we handle that, but we don't need
to worry the user by screaming errors.

Profiles are... interesting
https://github.com/cvuchener/g500/blob/master/doc/profile.md is pretty
detailed on the information, but there's some oddities.
The profile configured on my mouse is on page 5, not sure if that's the OS X
logitech tool though (which doesn't do profile configuration btw). Pages 3 and
3 are valid too, the rest looks to be garbage.
There's probably some magic string to detect a profile (cvuchener says maybe
FF 00 00 80), so more profiles may be lying around elsewhere in memory...

This also changes from the "toggle" to a plain "set". If a caller needs to
toggle a specific function, it can run get + set instead.

Only enabled for 4 leds and I'm not even sure they're the same on all
devices. Still, works on the G500s so that's a good enough start.

Looks a bit more like the hidpp20 driver now, and easier to get a handle on
everything. Command-specific functions/defines are grouped together and sorted
by command index.

Only two receiver-specific requests have a 0-based index, everything else
wants 1-indexed devices. This currently makes it impossible to address wired
devices with a device index of 0. Switch it around, so that we use a 1-based
index.

Still try to run the other commands though, they're not receiver-related and
may work on a device that's not on a unifying receiver.
