04d14c9b68 vc1: Split the decoder in components 
Speed up the overall compilation time.

4d55e9de27 vc1: Split bits used in libavformat into a separate header 
This reduces inter-library dependencies.

c2f7417eeb vc1: move MpegEncContext.resync_marker into VC1Context. 
The field still remains in MpegEncContext because it is used by the
mpeg4 decoder.

28243b0d35 vc1dec: Redesign the intensity compensation 
Use the intensity-compensated reference frame for subsequent
fields/B-frames.

Since we currently don't change the reference frame we have to
maintain lookup tables for intensity compensation in the following
dependent frames.

93b1281264 vc1dec: Shuffle field MVs after decoding, not before 
This simplifies the code since copying MVs to the reference is not needed
anymore (and maybe something about fixing artifacts).

Also remove the unused mv_f_last.

Fixes a small number of artifacts in black_screen_VC-1.mkv
and several more artifacts in other videos.

94ee7da08d Remove pointless av_cold attributes in header files 
The init functions marked as av_cold have to be executed in any case,
so there is no gain from trying to mark paths leading to such functions
as unlikely.

88bd7fdc82 Drop DCTELEM typedef 
It does not help as an abstraction and adds dsputil dependencies.

7627c35a81 vc1: export some functions 
This is a preparatory step for the MSS2 decoder which needs to use
the WMV9 decoder to decode some kinds of frames.

3c715383ea vc1: Move init code shared between decoder and parser to common code file. 
This fixes standalone compilation of the VC-1 parser.

c742ab4e81 vc1parse: call vc1_init_common(). 
The parser uses VLC tables initialized in vc1_common_init(), therefore
we should call this function on parser init also.

58bb6b7d93 wmv3dec: fix playback of complex WMV3 files using simple_idct. 
IDCT coefficients are read transposed, but simple_idct does not expect
this. Therefore, only do tranposed coefficient reading if we're not
using simple_idct.

987903826b Globally rename the header inclusion guard names. 
Consistently apply this rule: the guard name is obtained from the
filename by stripping the leading "lib", converting '/' and '.'  to
'_' and uppercasing the resulting name. Guard names in the root
directory have to be prefixed by "FFMPEG_".
