With the flag in place, it's hard to actually use the decoder, and
I'm happy with how it works, with the exception of DivX3 where I've
never found a sample that worked that I was confident actually
matched what the hardware claimed to support.

This might even have prevented the compiler from some optimizations,
since both signed and unsigned types are used for the dezigzag tables/
table pointers, and if a branches uses both the compiler needs to
create more complex code.

Before this, they were only added to the delayed release queue and not
freed until later. This could lead to unnecessary memory use or buffer
exhaustion.

This prevents decoding happening on a half initialized context.

lf_delta.ref[i] and lf_delta.mode[i] were incorrectly reset to 0 if
specific delta value was not updated. Fixed to keep the previous value
if flag indicates that element in question is not updated.

This makes sure the reset flag gets set when SBR gets turned back on
and sets control variables for unguided mode back to their defaults.

even into completely disabled code with no reason given
for that in the commit message.
