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

Janne Grunau cd8c64e197 Revert "mpeg12: move full_pel from MpegEncContext to Mpeg1Context" 
This reverts commit da22ba7df4 since it
broke slice threading. Slice threading just duplicates MpegEncContext
so every value used during mpeg_decode_slice has to be in it.
A second patch will fix the illusion that Mpeg1Context is available
in mpeg_decode_slice.

Måns Rullgård db2f209352 mpeg12: fix non-standard use of "extern inline" 
Rename ff_mpeg1_decode_block_intra to mpeg1_decode_block_intra and
make it static.  Add ff_mpeg1_decode_block_intra as plain extern
function calling mpeg1_decode_block_intra.

Stefano Sabatini 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_".

Diego Biurrun 071083b4a5 Rename ff_init_vlcs function to the more descriptive name ff_mpeg12_init_vlcs. 
Now that it is exported, this should avoid confusion and name clashes.
