* Move to BCodecKit namespace and make extensive use of BCodecRoster. * This is a first step in the right direction of decreasing private dependencies. Some APIs are being translated to the CodecKit. I am doing an investigation on which APIs are really used among apps, so that the new kit can be more slim and oriented toward easy development and can be extended in the right direction instead to continue maintaning unuseful code. * BMediaFormats needs still a bit of love. * General improvements in style and code maintainability.
