ffmpeg | branch: master | Stefano Sabatini <stefano.sabatini-lala at poste.it> | Fri Apr 15 16:42:09 2011 +0200| [59d96941f0285a501989d5f2c9b69be0a1393ed5] | committer: Anton Khirnov

avio: remove AVIO_* access symbols in favor of new AVIO_FLAG_* symbols

Make AVIO_FLAG_ access constants work as flags, and in particular fix
the behavior of functions (such as avio_check()) which expect them to
be flags rather than modes.

This breaks API.
