Since any value of dQ > 0 will cause the initial quantizer to
 degrade to the format-implied maximum (15) with a sufficient
 number of DRED frames, allow signaling a maximum smaller than 15.
This allows encoders to improve the minimum quality of long DRED
 sequences (at the expense of bitrate) without requiring a constant
 quantizer for all frames (dQ == 0).

Also, fix documentation about return value of zero.

Trying to add padding in-place breaks when we have extensions,
which causes a memcpy() with overlapping data. Just doing a
copy instead.

Allows us to exclude the most recent silence from DRED

Thanks to Igor Palaguta for reporting the issue.

Same for opus_multistream_packet_unpad()

Forgot to account for padding length bytes when DRED payload is large.

Need to move the redundant frame even in CBR because the hybrid
frame now gets encoded as VBR, with DRED picking up the rest.
Fixes an issue introduced in 4600e775.

The encoder wouldn't reserve enough bits for CELT, causing it
to not have enough bits to code the switching redundancy flag
when it should have.

Adjust q0, qD and duration based on bitrate and loss.
