From ffmbc0.3, this one appears to be a bugfix.

is correct.

Also more consistent with the rest of the code.

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.

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.
