The decode function assumes that the video will have those dimensions.

This prevents writing into a too small array if some parameters changed
without the tile being reallocated.

The value should be always 3, as it follows from the specification.
Fix a stack buffer overflow in exponents_from_scale_factors as reported
by asan. Thanks to Dale Curtis for the sample vector.
This way we can directly remap channels from Opus' channel order to
libav's internal channel order, instead of mapping channels from
Opus' order to Vorbis' order then to libav's order.

Do not use rlelen field for buffer size in init_get_bits, it is
only the size of the data for the first field.
Since it is not reliable, just use the size of the whole buffer.
Additional comments add removal of unused rlelen variable by
Reimar Döffinger.

This avoids using the global_quality field and QSCALE flag for
passing the VBR modes, since the value range of the global_quality
field doesn't really map cleanly to this codec's VBR modes.

These modes were not originally exposed by the library at all.
In practice, only a few of them work for each sample rate/profile
combination, and they don't work at all for the more uncommon
sample rates.
