CoreAudio: fix supported channel count.

We were using the number of channels actually used by audio devices as
the maximum channel count. This is wrong as CoreAudio can automatically
split or merge channels in order to accommodate the device.
We now assume all channel configurations are valid.

QNX: Remove most of the CPU overhead for video rendering

This patch uses the GL_OES_EGL_image extension to create a OpenGL Texture handle
for a libscreen pixmap. If the extension is not available it uses the "old"
technique as fallback where the image data is copied into a QImage.

This reduces the CPU load by more than 70% and allows HD videos to be played jitter-free.

BlackBerry: Fix the rotation of the viewfinder

This fixes the rotation of the viewfinder. We have to adjust the orientation
depending on the primary screen orientation. On a keyboard device, the viewfinder
would not rotate at all (same if auto orientation is turned off).

Fix unit tests

Random playback mode is not good for testing index changed signal,
because the same media might be played successively.
Calling show() might result in showFullScreen() on some platforms,
which is not expected by some video widget tests.

GStreamer: each QMediaPlayer now has its own volume by default.

We were using the volume property of GStreamer's playbin element to set
the volume. This could behave differently depending on the system
configuration; it could affect the system volume or the media player
own audio stream.
We now use a 'volume' element to do software attenuation on the audio
data sent to the audio sink, it allows each QMediaPlayer to always have
its own volume.
To preserve the previous behavior, developers can set the
QT_GSTREAMER_USE_PLAYBIN_VOLUME environment variable to true.

[ChangeLog][QtMultimedia][GStreamer] QMediaPlayer::setVolume() doesn't
change the system volume anymore (it could be the case before depending
on the system configuration). Set the QT_GSTREAMER_USE_PLAYBIN_VOLUME
environment variable to true to restore that behavior.

Tell glib not to complain about the use of API recently deprecated

When building with glib 2.32 or later, without this #define, it prints a
warning saying:

function "g_value_get_char" was declared deprecated ("Use 'g_value_get_schar' instead")

Since g_value_get_schar is new in 2.32, we can't use it without #ifdef
around the call point. Since the old and new functions are identical in
behavior, just ask glib not to complain about the use of old functions.

I don't know which is the minimum version of glib we require, so I went
for the lowest available macro.
