Ronald S. Bultje 291c9b6285 h264: change underread for 10bit QPEL to overread. 
This prevents us from reading before the start of the buffer, and thus
prevents crashes resulting from this behaviour. Fixes bug 237.

Ronald S. Bultje 45549339bc vp8: disable mmx functions with sse/sse2 counterparts on x86-64. 
x86-64 is guaranteed to have at least SSE2, therefore the MMX/MMX2
functions will never be used in practice.

Ronald S. Bultje bd66f073fe vp8: change int stride to ptrdiff_t stride. 
On 64bit platforms with 32bit int, this means we won't have to sign-
extend the integer anymore.

Martin Storsjö b087ce2bee g722: Fix the QMF scaling 
This fixes clipping if the encoder input used the full 16 bit
input range (samples with a magnitude below 16383 worked fine).
The filtered subband samples should be 15 bit maximum, while
the code earlier produced them scaled to 16 bit.

This makes the decoder output have double the magnitude
compared to before.

The spec reference samples doesn't test the QMF at all, which
was why this part slipped past initially.
