For large values of maxabs_Q20, silk_MUL( maxabs_Q20, ind + 1 ) could
overflow.

Reduces the XX values to avoid an overflow in silk_VQ_WMat_EC(), even in
floating-point.

more conservative scaling of LTP corrs; remove assert that checks for negative residual energy; discard CB entries leading to such negative energies

The NSQ SSE optimizations are disabled for now because they need to be updated

Only complexity 0-1 now uses the plain non-delayed-decision NSQ since its
quality is pretty bad. Previously 0-3 were using that plain NSQ.

Removes unused 64-bit version

A frame is marked as valid for DTX if it contains noise or only digital
silence. As before, there is an overhang period of 200 ms and a maximum
consecutive DTX period of 400 ms.

If the new DTX cannot be used because of the complexity setting and
sampling frequency chosen, the SILK DTX will be used instead.

JMV: edited to be a little more conservative
