Subject: [PATCH] avcodec/movtextdec: Switch to smaller type

The base size of a box refers to the size the box has in a file,
not in memory; so size_t is not their natural type. Therefore use
a plain unsigned which is smaller on 64bit systems and still big
enough to represent any conceivable base size.
