[FFmpeg-cvslog] avtools: parse loglevel before all the other options.

[Anton Khirnov]

ffmpeg | branch: master | Anton Khirnov <anton at khirnov.net> | Mon Sep 26 08:15:37 2011 +0200| [182cbe433aea20b0d9627d40de7c75713ec736db] | committer: Anton Khirnov

avtools: parse loglevel before all the other options.

This way it can be applied to cmdutils too -- e.g. showing the banner
and printing startup messages.
