[theora] Theora control and performance in liboggplay

I posted previously regarding seeking support for ogg streams. The
suggestion I got was to use liboggplay, and it works well for seeking, but I
have a few new problems.

1. I would like to call  theora_control in order to get/set PPLEVEL in order
to fine-tune performance under high-CPU load situations. However, it looks
like the relevant theora data structure is inaccessible.

2. I noticed that liboggplay is copying the entire contents of the decoded
frame into yet another structure before passing it to the user. I would like
access to the original frame from Theora for performance reasons. Someone
informed me off-list that there might be a version of liboggplay that
supports this.

Any suggestions?
