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

* Change the signature of the Writer plugins setup methods such
that they can modify the media_format passed in. For example they
can store information in the user_data section. I don't actually
use this anymore, but it may come in handy again.

AVFormatWriter:
* Adjust the AVCodecContext flags not only for video, but also
for audio streams (as the API example does). This mechanism
may not yet work, since the AVCodecEncoder actually uses a
different AVCodecContext instance.
* Use the encodeInfo->flags and specify the key frame flag
for the AVPacket. This finally makes videos encoded on Haiku
seekable.

* Also pass the media_codec_info to the Writer::AllocateCookie(), since that
info is not part of the media_format otherwise.
* Finished enough in the AVFormatWriter and AVCodecEncoder that we can now
actually create AVIs and MPGs and encode MPEG1, MPEG2 and MPEG4 video.
But no audio as of yet. Also, there is no bit-rate/quality setup, so it seems
libavformat is using the least possible bit-rate/quality.
* Enable some more muxers and encoders in the FFmpeg libs.
* Uses pixel format conversion from libswsscale, need to read the documentation
again, but I think it makes the plugin GPL.
* Fixed includes in libswscale/swscale.h, this is now an unmodified FFmpeg 0.5
header again (AFAICT).

* Tweaked the Writer API. Basically, we need an Init() method that takes the
media_file_format as input, so that the Writer knows what kind of file is
needed.
* Also, since information about the stream format is going to be needed at the
Writer level as well, the AllocateCookie() method gets the stream
media_format.
* Fleshed out some aspects of AVFormatWriter, many TODOs are left.

* 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.

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


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31987 a95241bf-73f2-0310-859d-f6bbb57e9c96

Resolved TODO, make it clear who maintains the allocation of the
media_file_format array (it remains with the plugin itself, as with
DecoderPlugins).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31955 a95241bf-73f2-0310-859d-f6bbb57e9c96

Added interface to WriterPlugin to get all supported media_format_families.
Don't yet know if that's the way it's supposed to work...


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31933 a95241bf-73f2-0310-859d-f6bbb57e9c96

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