From 0571bb4f1a6e1934ee7e093ce7aa517b9bac8e6a Mon Sep 17 00:00:00 2001

Subject: [PATCH] demux_ogg: partially port libtheora glue code to Theora 1.0
API
This partially backports the following commit to allow building
with gcc-5.x and otherwise fails to find the definition of
the _ilog function the way it is used.
