PulseAudio: make plugin more robust.

Handle more thoroughly error cases, such as when the PulseAudio daemon
does not respond or terminates while QAudioInput/QAudioOutput is
active, in which cases it used to crash or hang.

We now correctly emit the error signal and change the state when errors
occur.

AVFoundation: correctly pass output URLs to AVCaptureMovieFileOutput.

The URL string passed to NSURL was not fully encoded, causing the

Android: fix setting camera parameters from QML.

We were ignoring new parameter values when the camera was not loaded.
All QML properties that were set at initialization time were therefore
ignored since the camera is not loaded at that point.
We now store all camera parameters and apply them once the camera is
loaded.

DirectShow: Refactor camera backend.

Almost entire rewrite of the camera backend. It doesn't provide new
features but is more stable and behave as it should.

- Correctly report camera state and status
- Correctly report if the camera is ready to capture
- Emit imageExposed() signal
- Save captured images in an appropriate directory
- Images can be captured even without a viewport
- Better error handling

Removed the custom QVideoWidgetControl as it doesn't provide anything more
than the QVideoWidget's renderer control fallback.

CoreAudio: make sure audio stops playing when the device is muted.

The audio session's category was set to Playback, which implies that
audio is still audible even after setting the device to silent mode or
locking the screen. This shouldn't be the default behavior.
We now set it to Ambient, which preserves mixing with other apps
but makes sure sound is turned off when it should.

QMediaNetworkPlaylistProvider: Upon error parsing, stop parsing.

When an error is found parsing a playlist, stop parsing. This will also prevent
the emission of the "loaded" signal when the parser finishes.

Some of the newly added testcases do not yet pass because the parser is overly
strict. These improvements are being tracked in QTBUG-40515.

Implement more full resource policy features.

 * Handle released by manager properly.

Signal resourcesReleasedByManager is different from signal
handleResourcesLost and needs to be handled separately.
Signal handleResourcesLost means some other client has acquired the
resources, thus the resources are lost from us, but if the other client
frees the resources, we will automatically get the resources back.
With resourcesReleasedByManager we lose the resources, and resource
manager releases them as well (same as if client would call release()),
so only way to re-acquire resources in latter case is calling acquire()
again.

This distinction is useful for example in cases where user is listening
to music with headphones connected and removes the headphones, then the
music player shouldn't continue playback until user requests so. But if
user is listening to music when phone call is received, it is convenient
to resume the playback automatically after the call.

 * Implement availability changed.

Availability changed is information whether resources the client is
interested in are available (no higher priority resource classes have
acquired the resources).

 * Implement missing resources released.

Emit resourcesReleased signal when receiving corresponding signal from
libresource-qt.

 * Add mechanism to change used resource class.

Check for environment for special variable, and if the variable has
proper data, use that as the resource class. Can be set with for example
qputenv("NEMO_RESOURCE_CLASS_OVERRIDE", "game");

Only call pa_cvolme set on stream creation if volume explicitly set.

Streams without a custom volume set use suitable volume selected
by the PulseAudio server. This is usually the correct choice, since then
stream-restore module can apply old volume to the stream. Also with
Sailfish explicitly setting the volume to streams breaks system volume.

Resource policy support for QSoundEffect.

Since sound effects are something short and mixed with other audio, do
not acquire resources explicitly. Follow the resources availability
information to determine when it is ok to play the sound effects.

When client has registered itself to resource manager, client's streams
are classified properly. If no higher priority client has acquired the
resources, isAvailable() is true, and sound effects can be played. We
do not explicitly acquire the resources, since then other clients with
the same resource class would lose the resources, thus not possible to
have second client play music with QMediaPlayer class while our client
would just want to play simple sound effects.
