At least in the DBus API we can't just say "doesn't exist", so let's allow for
a zero-sized list.

Previously, we could get a min/max value but there was no guarantee that it
any value in between would actually work on the device. Some devices have a
discrete number of resolutions (e.g. 500, 1000, 2000, 2500), most others have
at least a minimum step size (so 1234 isn't a valid dpi value).
Change the min/max to a discrete list of which resolutions are supported. This
allows a UI to adjust its interface dynamically - e.g. a combobox if there are
only 3 resolutions or a slider if there are a million of them.
This is a DBus API break

Better than the markdown we were using before, even though we're currently
(ab)using the js/c++ domains for the structure. There is no DBus domain in
sphinx yet.
The main motivation was to get the enums into the documentation since they are
exported ABI.
Generating the documentation is quirky - we use doxygen to extract the
comments from the C header file and then use XSLT to convert to .rst which
sphinx can use. Still better than having to maintain even more copies of the
enums.
Since this is only of interest for maintainers that need to upload the
documentation, it is turned off by default.
