Upgrade to librespot 0.5

[davidgauch]

There are a number of breaking changes in the Librespot 0.4 to 0.5 release.
There are 3 TODO comments that correspond to future feature work. I tried to do the minimal changes to get this working.

Thank you for tackling this major task! Looks good so far.

I actually started working on this as well, and definitely should've opened a draft PR for this to avoid duplicating the work. :/ If you want to have a look, my changes are here. Like you, I'm also still missing the necessary changes to dbus_mpris.rs. I wanted to get rid of rspotify there, so started replacing all the calls to the web API with respective librespot calls, but there's still some stuff missing.

So I'm not sure what should be done now. If you have the time to get MPRIS support working, we could just merge your version and I would rework the MPRIS logic at some later point. Otherwise, I could of course also try to finish my version and look through your stuff, if there are parts that I missed.

thanks for all the work you put into this! I tried to compile and run it without credentials today and I gotta say that upon connecting to it, it just says
failed to create spirc: Service unavailable { Session is not connected }

Using credentials results in
failed to connect to spotify: Permission denied { Login failed with reason: Bad credentials }

... and I'm 100% sure that the credentials are correct btw

any information about this?

Compilation fails at:

src/dbus_mpris.rs:18:5 could not find `keymaster` in `librespot_core`
src/dbus_mpris.rs:21:5 no `SpotifyAudioType` in `spotify_id`
src/dbus_mpris.rs:595:26 variant not found in `PlayerEvent`

Haven't done anything in Rust before, but might give it a try later.

On the other hand, librespot v0.6.0 just released a few hours ago.

No worries, I did most this work before librespot released (I was trying to debug an auth issue). I wouldn't mind you closing this.

If you'd like though I can take a stab at mpris later today in about 10 hours.

I would also be willing to bump librespot again to 0.6.0 which was released 18 hours ago.

I messed with the codebase for a while this evening. I have fixed the compiler bugs but I can't seem to get it to run properly. spotifyd starts, shows up in the web client as a device, claims an authentication success, but then crashes.

I tried incorporating the changes you made to main_loop.rs but that didn't seem to resolve the issue, just change how the crash error I get.

I think you're probably better-equipped to actually debug this issue @eladyn

Before checking here to see what others were doing, I made a patch (attached) to make spotifyd at least compile with librespot 0.6.0. I do not really know rust so I probably borked something, but perhaps pieces of the patch will be useful to someone in moving your pull requests along.
