Register media add-ons on BMediaFormat::GetFormatFor().

* Fixes #11018.
* In this case the FormatManager format list is accessed without going
throught the AddOnManager, so we must tell the AddOnManager to register
the add-ons (as this is what populates the FormatManager format list).
* Remove now unneeded workaround in mp3_decoder_test.

FFMPEG Plugin: Automatic detection of audio decoding parameters.

- Kudos to Marcus Overhagen for laying out the general idea of automatic
detection by sharing some of his dvb code examples with me.
- Automatically detect the audio frame rate, channel count and sample format.
- Share audio sample format conversion code between AVFormatReader and
AVCodecDecoder.
- Tested with several video and audio files via MediaPlayer.
- Tested also with test case mp3_decoder_test -after- removing the hard coded
audio decoding parameters. Although the test shows that auto detection is
working (via stepping through the auto detection code path) the complete test
is still failing, due to missing implementation of incomplete audio frame
decoding.
- Add and update the documentation accordingly.

Media Kit: Add workaround for #11018 to MP3 audio stream decoder test.

The workaround triggers the loading of all media plugins prior to using
methods of class BMediaFormats. Using the function get_next_encoder()
is used because of two facts

1. It is publicly available and thus can be used by 3rd party apps,
too.
2. It is already available by including BMediaFormats.h, so there is
no need to include another header for this workaround.

Media Kit: Add MP3 audio stream decoder test.

- This test currently fails and thus showing that there is something wrong in
the Media Kit.
- This test was first developed and tested on Haiku R1 Alpha 4.1 where
every thing was hacked together to make this test succeed, thus showing that
the current Media Kit state of affair has some issues and not this test :)
- The test comes with documentation (@see mp3_decoder_test.cpp).
