[MPlayer-dev-eng] [PATCH] remove useles ff_gcd prototype in demux_lavf

[Reimar Döffinger]

Hello,
avutil.h via common.h properly defines ff_gcd, so we shouldn't need that
prototype anymore.
avformat.h currently in some ways already includes the things needed in
some obscure way, but including avutil.h explicitly probably is better.
Is attached patch okay?

Greetings,
Reimar Döffinger
