As the portal documentation [1] says:
Bitmask of what device types to request remote controlling of. Default is all.
The default is only triggered if we do not submit the types at all, the
current behavior of sending a value of 0 means "none". Fix this by
skipping the "types" key if we try to select for all devices.

DBusMock is unittest based and the documentation points users to that
approach. That approach is limiting however because we can't use all
pytest features (see [1]). Luckily, the parent class in dbusmock doesn't
really do much so we can emulate the functionality ourselves - all we
need to do is call the same setUp/tearDowns and be done with it.
This means we can move the dbus-monitor and mainloop handling into
fixtures too which makes the code a fair bit nicer to read.

Since the soname was added, the liboeffis.so file no longer exists in
the build directory - it is created on install.
Not sure how this passed the CI pytest run but it certainly fails
locally.
libei used to have direct portal support code (see the git history) but:
- that code was a custom proposed portal that never went anywhere
- libei has slowly changed to be more an input event transport layer since
it is now also used sending events *to* a libei context
- a number of libei users will never need the DBus code, either because they
don't want it or because they talk Dbus themselves na ddon't need this
abstraction.
Luckily, it's quite easy to move this into a separate library with a
simple API that does, effectively, the same trick as the old portal backend.
This API is aiming to be as simple as possible because the tools that
require anything more complex should talk to DBus directly.
An example tool that uses the API to retrieve an EIS fd over the
RemoteDesktop portal is included in this patch.
"Öffis" is a German word meaning public transport. It also sounds like the
French Œuf, the word for egg.
