Port to upstreamed versions of Audio Role patch

These are the build logs of qtubuntu-media against the new Qt 5.5 (+ patches) in 012:

https://launchpad.net/~ci-train-ppa-service/+archive/ubuntu/landing-012/+sourcepub/5379430/+listing-archive-extra

"error: 'QMediaPlayer::AudioRole' has not been declared"

This change affects qtubuntu-media and I would expect it to not compile without updates to reflect the upstream changes to the audio role patch that was already previously submitted.

This would seem to affect Unity 8 too, and is currently blocking starting up Unity 8 on Qt 5.5 (after hacking around a few other problems):

file:///usr/share/unity8//OrientedShell.qml:147:5: Type Shell unavailable
         Shell {
         ^
file:///usr/share/unity8//Shell.qml:635:9: Type Notifications unavailable
             Notifications {

file:///usr/share/unity8//Notifications/Notifications.qml:47:15: Type Notification unavailable
         delegate: Notification {
                   ^
file:///usr/share/unity8//Notifications/Notification.qml:85:9: "Audio.audioRole" is not available in QtMultimedia 5.0.
             audioRole: MediaPlayer.alert
             ^

The upstreamed version is at http://anonscm.debian.org/cgit/pkg-kde/qt/qtmultimedia.git/tree/debian/patches/Add-audio-role-API-to-QMediaPlayer.patch?h=ubuntu

So for example s/audioRole/Role/ under Audio, and different MediaPlayer.* roletypes.

Qt Ubuntu Media builds and seems to run with the MP now attached to this bug report.

The Unity 8 starts if I comment out the two offending lines from Notifications/Notification.qml + Components/ScreenGrabber.qml

For some reason I was not able to figure out how they should be changed immediately to set the role without getting some QML error. I changed the backported qtmultimedia patch a bit to state 5.5 - https://launchpadlibrarian.net/220262357/qtmultimedia-opensource-src_5.5.0-3ubuntu1~wily1~test4_5.5.0-3ubuntu1~wily1~test5.diff.gz - and I changed the Unity 8's qml files to import QtMultimedia 5.5 instead of 5.0.

For Unity 8, I tried Role: MediaPlayer.NotificationRole which seemed the closest match.

Also needed is qtubuntu-camera.

Regarding the Unity 8's audioRole usage from QML:

---
    Component {
        name: "QDeclarativeAudio"
        prototype: "QObject"
        exports: ["QtMultimedia/Audio 5.0", "QtMultimedia/MediaPlayer 5.0"]
        exportMetaObjectRevisions: [0, 0]
...
 Property { name: "audioRole"; revision: 1; type: "AudioRole" }
---

So I guess it should be available with audioRole = MediaPlayer.NotificationRole (and Audio.NotificationRole) but the Audio.audioRole is being blocked because it's marked as revision: 1? Could someone have tell the proper way to use it, since it seems I wasn't able to guess correctly?

I'm not sure I understand why it's blocked because of revision 1? I'm not familiar enough with how the declarative object exporting works in regard to revisions. Is it blocked because it's exporting as revision 1 of the parent object, which is QDeclarativeAudio?

Assigned pulseaudio part to David with a tip from Jim. We at least to know if pulseaudio needs to be changed for this or not.

Fix committed into lp:ubuntu-clock-app at revision 411, scheduled for release in ubuntu-clock-app, milestone 3.7

There doesn't seem to be anything explicitly off even without updating media-hub and pulseaudio, so therefore marking them as needing more information. Do they need to be patched and if, how?

I'm currently in process of emailing with mpt about how we should handle this for media-hub and pulseaudio. I just sent this out yesterday, so I don't know his thoughts on this quite yet.
