* Changed the VideoSupplier interface to allow forcing the
video generation. This allows step back frame-wise even though
it means the video has to seeked back far and re-generated more
than five frames ahead to reach the seek frame.
* Don't print dropped frames in the producer when the video
is paused.
* Don't lock the PlaybackManager to report dropped frames,
report it later when the manager had to be locked anyway.
* Removed a whole bunch of methods that were only implemened
because of that old BeOS PPC compiler bug.

* Instead of using some bogus latency for the VideoProducer,
compute the latency from the buffer count. It should be
the duration of in-flight buffers (i.e. number of buffers
minus the one currently showing).
* Compute the wakeUp time based on the buffer latency used
above.
* Make the "wasCached" mechanism work again, i.e. don't send
the buffer to the consumer if the contents did not change.
This removes the need to cache frames in the ProxyVideoSupplier
and thus one more memcpy() (5ms on my Q6600 for full-HD content).
* Remove the weird forceSendingBuffer override and the setting
of the header starttime to 0. Now seeking clips works also
when the playback is paused.

All in all, playback is more efficient now, and the chances of
dropping frames are much less. Something is still fishy, though,
since VLC, even though seemingly using slightly more CPU, drops
frames more seldomly than MediaPlayer. Audio/Video sync seems to
be better, though, since the VideoProducer is using a more accurate
latency now.

Set the processing latency using the time it
took to decode the last frame.

* Make PlaybackManager::CurrentFrame() return int64, like
what it's internally using. Adapt NotifyCurrentFrameChanged()
implementors.
* Controller::SetTo() does not need to set the current frame,
since either Init() or FormatChanged() will have taken care
of it now.
* Reset the seeking request info in Controller::SetTo().
* Changed the parameter passed to VideoSupplier::FillBuffer()
from media_format to media_raw_video_format, so the
VideoProducer doesn't have to generate a media_format for
each frame...
* ProxyVideoSupplier caches the last produced frame, which
avoids a situation that the VideoProducer asks to generate
the same frame twice sometimes.
* In PlaybackManager::_PushState(), make sure we really
schedule the next current_frame if asked. This avoids
one situation in which the VideoSupplier was asked to generate
the same frame again and fixes playback after pausing (was
showing black video until the next keyframe before.

Don't try to decode more than 5 frames at a time to reach
the seek frame. It's just not such a good strategy, since
it appears to be faster to just wait until the next keyframe
is reached naturally.

The seeking algo stopped decoding frames one frame too early.

Fix a locking problem with inner locks to protect the race condition when
the producer media nodes would access the suppliers in their own thread
without having any locks held, while the window could replace the suppliers.
I think since I delayed the deletion of the suppliers in the controllers, this
problem was only theoretical... but this is just more clean.

* Moved a bunch of non-primary interface classes into a new subfolder
"interface"

* Complete reimplementation of the playback engine using Media Nodes:
- Seeking video files does not appear to lockup the playback anymore, but
works on a frame accurate level even for keyframe based streams. There is
currently a problem with certain container formats, the audio track reports
a "Device Seek Error" in certain conditions. In that case audio goes silent,
and can be restarted by going back to the beginnings of the stream.
- Video overlays are now supported.
- It would be possible to connect the output of the MediaPlayer to other
applications or dormant media nodes.

* Known regressions:
- The volume slider has currently no effect anymore.
- Switching the audio track during playback has a known race condition and
can crash the player.
- The new engine is not as "light weight" as the old one. I tagged the
previous implementation in tags/components/mediaplayer-engine-v1. It does
not seem to have any noticable effect though.
