50833c9f7b Fix buffer_size argument to init_put_bits() in multiple encoders. 
Several encoders were multiplying the buffer size by 8, in order to get
a bit size. However, the buffer_size argument is for the byte size of
the buffer. We had experienced crashes encoding prores (Anatoliy) at
size 4096x4096.

b9de1303a6 mips/acelp_filters: fix incorrect register constraint 
Change register constraint on the v variable from = to +. This was causing GCC
to think that the v variable was never read and therefore not initialize it.

This fixes about 20 fate failures on mips64el.

03f39fbb2a avcodec/x86/mlpdsp_init: Simplify mlp_filter_channel_x86() 
Based on patch by Francisco Blas Izquierdo Riera
Commit message partly taken from carl

fixes a compilation
error in mlpdsp_init.c with -fstack-check and some gcc compilers (I
reproduced the issue with gcc 4.7.3) by simplifying the code.
