mplayer2: fix building with gcc 5.x
This patch works around a potential problem in the theora glue code where it assumes that the compiler will somehow find a function which is not exported explicitly through the libtheora library. Due to this problem the build fails with gcc-5.x compiler. The included patch essentially backports a commit which updates the glue code to use the Theora 1.0 API to eliminate this problem and PNBLACKLIST is cleared for mplayer2.

+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.
