Remove win32/qt/xanim/real binary codecs loading

Remove the win32 loader - the win32 emulation layer, as well as the
code for using DirectShow/DMO/VFW codecs. Remove loading of xanim,
QuickTime, and RealMedia codecs.

The win32 emulation layer is based on a very old version of wine.
Apparently, wine code was copied and hacked until it was somehow able
to load a limited collection of binary codecs. It poked around in the
code segment of some known binary codecs to disable unsupported win32
API calls to make them work. Example from module.c:

    for (i=0;i<5;i++)  RVA(0x19e842)[i]=0x90; // make_new_region ?
    for (i=0;i<28;i++) RVA(0x19e86d)[i]=0x90; // call__call_CreateCompatibleDC ?
    for (i=0;i<5;i++)  RVA(0x19e898)[i]=0x90; // jmp_to_call_loadbitmap ?
    for (i=0;i<9;i++)  RVA(0x19e8ac)[i]=0x90; // call__calls_OLE_shit ?
    for (i=0;i<106;i++) RVA(0x261b10)[i]=0x90; // disable threads

Just to show how utterly insane this code is. You wouldn't want even
your worst enemy to have to maintain this. In fact, it seems nobody
made major changes to this code ever since it was committed.

Most formats can be decoded by libavcodecs these days, and the loader
couldn't be used on 64 bit platforms anyway. The same is (probably)
true for the other binary codecs.

General note about how support for win32 codecs could be added back:

It's not possible to replace the win32 loader code by using wine as
library, because modern wine can not be linked with native Linux
programs for certain reasons. It would be possible to to move DirectShow
video decoding into a separate process linked with wine, like the
CoreAVC-for-Linux patches do. There is also the mplayer-ww fork, which
uses the dshownative library to use DirectShow codecs on Windows.

-/* The following is a short description of the AVI file format.  Please
- * see the accompanying documentation for a full explanation.
- *
- * An AVI file is the following RIFF form:
- *
- *	RIFF('AVI'
- *	      LIST('hdrl'
- *		    avih(<MainAVIHeader>)
- *                  LIST ('strl'
- *                      strh(<Stream header>)
- *                      strf(<Stream format>)
- *                      ... additional header data
- *            LIST('movi'
- *      	  { LIST('rec'
- *      		      SubChunk...
- *      		   )
- *      	      | SubChunk } ....
- *            )
- *            [ <AVIIndex> ]
- *      )
- *
- *	The main file header specifies how many streams are present.  For
- *	each one, there must be a stream header chunk and a stream format
- *	chunk, enlosed in a 'strl' LIST chunk.  The 'strf' chunk contains
- *	type-specific format information; for a video stream, this should
- *	be a BITMAPINFO structure, including palette.  For an audio stream,
- *	this should be a WAVEFORMAT (or PCMWAVEFORMAT) structure.
- *
- *	The actual data is contained in subchunks within the 'movi' LIST
- *	chunk.  The first two characters of each data chunk are the
- *	stream number with which that data is associated.
- *
- *	Some defined chunk types:
- *           Video Streams:
- *                  ##db:	RGB DIB bits
- *                  ##dc:	RLE8 compressed DIB bits
- *                  ##pc:	Palette Change
- *
- *           Audio Streams:
- *                  ##wb:	waveform audio bytes
- *
- * The grouping into LIST 'rec' chunks implies only that the contents of
- *   the chunk should be read into memory at the same time.  This
- *   grouping is used for files specifically intended to be played from
- *   CD-ROM.
- *
- * The index chunk at the end of the file should contain one entry for
- *   each data chunk in the file.
- *
- * Limitations for the current software:
- *	Only one video stream and one audio stream are allowed.
- *	The streams must start at the beginning of the file.
- *
- *
- * To register codec types please obtain a copy of the Multimedia
- * Developer Registration Kit from:
- *
- *  Microsoft Corporation
- *  Multimedia Systems Group
- *  Product Marketing
