Revert the Codec Kit.

All of Barrett's individual reverts have been squashed into this
one commit, save a few actual bugfixes.

Change-Id: Ib0a7d0a841d3ac40b1fca7372c58b7f9229bd1f0

Initial implementation of BMediaEncoder

* People interested, please review!
* This is based on the patch from Fredrik Moden which was based on
the Oleg Krysenkov one.
* The original patch has been reworked by myself.
* Adapted the code to work with the new PluginManager API which
differently than before doesn't need to contact the media_server.

Encoder:
* Fleshed out the Encoder API to support parameter setters/getters and returning
a BView for configuration. (Not yet sure if this is a good idea.)

BMediaTrack:
* Implemented all but one of the unimplemented methods in BMediaTrack. It should
be working as far as that class is concerned, unless I missed some of the
vision. ReplaceFrames() remains a stub, added a comment on why it probably
stays that way.
* Release the Encoder reference in the destructor.

FFmpeg plugin:
* Refactoring to delay opening the AVCodec until encoding the first chunk,
so that we can still adjust parameters.
* Support adjusting parameters via [Set|Get]EncodeParameters(). Currently,
only quality is supported, added TODOs about supporting the bit_rate setup
versus the automatically calculated bit_rate.
* Extended EncoderDescription by a bit_rate scale. The Encoder calculates the
raw bitrate needed by the current media format, and then divides that
number by the specific codec's bit_rate_scale, while taking into account the
desired quality. This seems to work very well already (tested with MPEG4),
although a lot more parameters could be specified for libavcodec, depending
on the desired quality.
* Enabled the ogg muxer in libavformat, although it is currently still disabled
in MuxerTable.cpp, because it rejects unknown codecs. Added TODO to this
effect.

* Writer::WriteChunk() takes media_encode_info* instead of flags.
* Improved Encoder API towards what we need for the get_next_encoder() variants
and the BMediaTrack API.
* Implemented the rest of MediaWriter. Still undecided what to make of
AddTrackInfo(). BMediaEncoder has that as well, which hints that this is
something the Encoder needs to support. But it could also be that this is
only possible to support in Writer.
* Wired a lot of previously unimplemented methods in BMediaFile and BMediaTrack
needed for write support. If I have not overlooked anything, only the
parameter stuff is still unimplemented now.

This is all untested, since the FFMpeg Encoder and Writer are still only stubs.

Implemented support for get_next_encoder() variations from MediaFormats.h.
The AddOnManager in the media_server registers one encoder entry per
successful EncoderPlugin::RegisterNextEncoder(). This gives us a first idea
what media_format_family and input/output media_type is supported. The
mechanism may have to be extended, or the Encoder needs an API to specialize
a format further. In that case, the get_next_encoder() version that takes
optional _acceptedInput/OutputFormat needs to instantiate the plugin and
needs to ask the Encoder. But AFAIK, no app uses it like that anyway.

Changed the way Encoders are published by EncoderPlugins. Encoder retrieval
in PluginManager is reenabled. We use the media_codec_info.id to reference
a specific plugin, while the sub_id will be used to reference individual
Encoders that the plugin supports. No idea if that's how it was intented, but
some comments hint in this direction. I failed to mention this before, but
comments are of course very welcome on any of these commits, as always.

Let's call it WriteChunk() instead of WriteNextChunk() and make the signature
consistent everywhere (according to BMediaTracker::WriteChunk()).

Beginnings of Encoder[Plugin] and Writer[Plugin] base classes and add-on
management.
