BPD: Update to newer MPD protocol version

[simonwjackson]

When running ncmpcpp, i get the following error message:

NCMPCPP: MPD < 0.16.0 is not supported

Can this be resolved by reporting a different version number to the clients? Or is there a fundamental difference in the code?

Thanks for pointing this out. If you (or anyone) is interested in tackling this, the first step will be to answer that question: identify what has changed between the protocol we implement and 0.16.0+.

According to the mpd command reference, it seems like the new stuff after 0.13.0 (the version implemented by the bpd plugin) are:

• idle command (probably the most important. it is the reason ncmpcpp can only work with >0.16.0)
• single, consume, nextsong, nextsongid, elapsed parameters in the status command
• single, consume playback options
• auto replay gain mode
• move playlist command
• playlistinfo command
• rangeid playlist command

I will look into implementing these changes so we can bump the proto version up to 0.19.0

Fantastic; thanks for looking into it!

Thank you Tiago! I've been wanting BPD working again for a long time now.
This is a dream come true. (Seriously, i was dreaming about this the other
night. My girlfriend tells me i'm a geek or something).

Any progress on this? Would love to be able to use ncmpcpp with bpd 😄

If anyone is still following this issue, this is an update to say that we're almost there! I have a pull request in progress (#3214) that is aiming to finish off the final missing parts of the MPD protocol support for 0.16. It's at a stage where it's now talking to ncmpcpp and basic things like changing songs seem to work.

Simple clients like mpdscribble, mpDris and mpc all seem to be working OK. The more complex clients like MPDroid, M.A.L.P. and ncmpcpp are all still broken to varying degrees. I've been keeping a list of problems in the description of the PR and gradually addressing them. If you'd like to help this effort it'd be great to test out some of your favourite MPD clients with the code in that PR and report back about any further issues you find.

@arcresu Thanks for the hard work!
