d4be08e0c9 Make X264_init() no longer assign avctx->rc_eq to libx264's context. 
Fix a crash due to X264_init() setting the libx264 rc_eq field to NULL
when rc_eq was not defined. As a consequence rc_eq can no longer be
manually specified and passed to libx264, but this option is going to
be removed from the libx264 public API anyway.

See the thread: "Fix crash in libx264 when rc_eq is not set".

eca0bcb66e While APE changed container format in 3.98, frequency tables for range coding

This fixes decoding of v3.98 APE file I have.
