8437cc7206 ffv1dec: Avoid unnecessarily large stack usage and copies. 
Ideally the compiler could figure this out on its own,
but it seems it can't.
An alternative that would avoid the messy explicit memcpy
would be to use a sub-struct for the parts that should
be preserved, which can then simply be assigned.

Mostly not merged, the added checks, check for impossible conditions
for paranoias sake they are replaced by asserts but thats probably overkill
the vlc table does not contain out of range values or holes,
nor does it permit the log2 values to become negative. Whenever a
log2 value reaches 0 the selected table no longer contains an entry to trigger
the case that would decrease it further

Adding such impossible checks would confuse the reader
