though the max chunk/payload sizes were checked and would fail the
padded size was being calculated beforehand which could result in a
(harmless) unsigned int overflow warning.

After ParseAnimationFrame() calls StoreFrame(), check if StoreFrame() reads
more than anmf_payload_size bytes from dmux->mem_. Treat that as PARSE_ERROR.

some multiplies here and there needed some extra checks
and error reporting. Even if width * height is guaranteed
to be < 2**32, we were multiplying by num_channels and
triggering a 32b overflow.
Some multiplies were not using size_t or uint64_t, additionally.

This is designed for the simple use-case where one wants to decode all
frames one-by-one in order.
Also, use this API in anim_util library, which is in turn used by
anim_diff tool.
