change from ffmbc

Also more consistent with the rest of the code.

git-svn-id: file:///var/local/repositories/ffmpeg/trunk@20848 9553f0bf-9b14-0410-a0b8-cfaf0461ba5b

This looks too ugly. Idea also from ffmbc.

Idea from ffmbc, code not, mine is a fraction of the size due to simpler
metadata API.

Merged from ffmbc.


git-svn-id: file:///var/local/repositories/ffmpeg/trunk@20841 9553f0bf-9b14-0410-a0b8-cfaf0461ba5b

somewhat based on ffmbc

Code from ffmbc with changes to adapt to our metadata API.

I cannot use the same ABI as ffmbc as value 2 is already used in ffmpeg,
besides the name AV_METADATA_NONCONST* makes no sense to me.
Add av_metadata_set2() that takes flags.

Without this random changes to the header inclusion can trigger
linking failures, and these are not even picked up in some environments 
(some fate machines didnt catch it).

This as a sideeffect fixes the linking failure of ffplay.

word, so treat it this way instead of extracting different parts from 32-bit
value.

instead of many strcmp() on always four-byte strings.
