bb59156606 vp8: fix signed overflows 
In addition to avoiding undefined behaviour, an unsigned type
makes more sense for packing multiple 8-bit values.

ac6eab1496 put_bits: fix invalid shift by 32 in flush_put_bits() 
If flush_put_bits() is called when the 32-bit buffer is empty,
e.g. after writing a multiple of 32 bits, and invalid shift by
32 is performed.  Since flush_put_bits() is called infrequently,
this additional check should have negligible performance impact.
