When going back to normal rate after playing in fast forward (greater
than 2x), playback seemed frozen for some amount of time (up to 8
seconds).
When playing in fast forward, only key frames are shown, ignoring all
the others. When returning to a normal rate, the source reader will
usually be pointing to a key frame in the future compared to the
player clock position, meaning that all the frames in between won't be
shown until the player clock catches up with the latest key frame that
was read.
When leaving fast-forward, we now reset the position on the player to
force the source reader to point back to the frame at the current clock
position and avoid the seamingly frozen playback.
Also, emit playbackRateChanged() signal when changing the playback
rate.

Instead of setting the volume on the audio session, which is shared by
all QMediaPlayers, we now set the volume on the media player's own audio
stream. This results in all QMediaPlayers correctly having independent
volumes.
[ChangeLog][QtMultimedia][Windows] QMediaPlayer::setVolume() does not
affect the volume of other QMediaPlayers anymore.

When using our custom MediaSink with RGB formats, Media Foundation fails
sometimes to resolve the topology. Inserting ourselves a ColorConverter
transform in the topology resolves the problem.
The ColorConverter transform cannot handle dynamic frame size changes
(this can happen with H264 videos for example) so we also need to insert a
Resizer transform to handle transparently frame size changes.

Fixed the way the custom MF Transform (getting the frames) works:
- Recreate it whenever we load a new media
- During media type negotiation between nodes, the MFT should support
the same types as the video sink supports
- Allow input and output types to be changed as many times as needed,
otherwise the topology cannot be resolved in some cases

MFMediaSession doesn't seem to handle correctly the change of media
source, causing the playback not to work afterwards.
A single MFMediaSession was created and used for every loaded media, we
now create a new one whenever we load a new media (releasing the old one
beforehand).

As in the past, to avoid rewriting various autotests that contain
line-number information, an extra blank line has been inserted at the
end of the license text to ensure that this commit does not change the
total number of lines in the license header.
