8157b5d405 lavc/vvc: Remove left shifts of negative values 
VVC specifies << as arithmetic left shift, i.e. x << y is equivalent to
x * pow2(y).  C's << on the other hand has UB if x is negative.  This
patch removes all UB resulting from this, mostly by replacing x << y
with x * (1 << y), but there are also a couple places where the OOP was
changed instead.

cad35f0a77 avcodec/speexdec: relax the extradata check for the speex string 
There could be bogus bytes at the start, as is the case of
vp5/potter512-400-partial.avi from the FATE suite, which could be a case of bad
remuxing from an OGG source.

Partially fixes decoding of vp5/potter512-400-partial.avi
