Upgraded FFmpeg to the release version 0.6 (only some minor compile fixes to the code

Browse Source 
with regards to using the wrong #include scope in one file and disabling two
apparently unmaintained asserts when compiling in DEBUG mode). I didn't yet test
the GCC 2 build, but I need to get this into SVN since I am having some annoying
file corruption troubles. In fact I am hoping I am not commiting broken files,
but a few seconds ago everything was still building cleanly. One thing that definitely
improved is the (disabled at the moment) AVI support. Every clip I tested so far
plays, which can't be said about our native AVI reader. With the previous FFmpeg
version (a random SVN revision is my guess), many old AVIs played completely broken.
So far, I have not spotted any regressions

* Summary of MDCT Coefficient Grouping:
* The individual MDCT coefficient indices are often referred to in the
* (E-)AC-3 specification as frequency bins. These bins are grouped together
* into subbands of 12 coefficients each. The subbands are grouped together
* into bands as defined in the bitstream by the band structures, which
* determine the number of bands and the size of each band. The full spectrum
* of 256 frequency bins is divided into 1 DC bin + 21 subbands = 253 bins.
* This system of grouping coefficients is used for channel bandwidth, stereo
* rematrixing, channel coupling, enhanced coupling, and spectral extension.
