59f733d1b1 2x faster ff_h264_init_cabac_states(), 4k cpu cycles less. 
Sadly this is just per slice so the speedup with normal files should be negligible.

85207e38dc Add lsp.o as a dependency for wmavoice. This fixes a compilation error when 
you disable lots of stuff (in particular other voice codecs) but leave
wmavoice enabled.
