Support for MP3 audio streams, using the minimp3 decoder. Adresses this feature proposal: godotengine/godot-proposals#85

Tested to be working with mono, stereo, and joint stereo encoded files.

Tested and working on both Windows and Linux.

Turns out, I should have tested this on other platforms than Windows. I'm fixing it ASAP. Done.

EDIT: Minimp3 uses variable shadowing, which needs to be specifically allowed through a compiler flag when compiling for Linux. I'm not sure if that's a good idea, but it seems to be working.

Looks pretty good to me, just some nitpicks, and a rebase is necessary as some core headers were moved recently in the master branch (so you'll have to propagate this in your own includes).

The warnings should only be disabled for thirdparty code, not for Godot files.
Here the thirdparty code is only headers so it's a bit tricky. I'd suggest trying without disabling warnings, and if some warnings are raised in the headers, then we'll have to use -isystem to include them to the include path.

Okay, I wasn't sure about that one. I changed it to use -isystem now.

Thanks! And congrats for your first merged Godot contribution 🎉

If you want to prepare a backport of this feature to the 3.2 branch, I think that'd be useful for many Godot users.
