Due to a shortcoming in the AAC specification, if an all zero buffer is
fed to section data decoding it will never terminate. That means without
a buffer exhaustion check decode_band_types() will consume all input
buffer padding. Worse if a get_bits() implementation that returns zeros
when padding is exhausted is used, the function will never terminate.

The fixes that by added a buffer exhaustion check in the sectioning
decoding loop.

same speed as far as i can meassure but it might have fewer branches on some
archs.

MPV_common_init(), so calling both is redundant and leads to memory
leaks in WMV3/VC-1 decoder. Thus use only the first function in
WMV3/VC-1 decoder initialization.

ff_combine_frame() is called, which allocates ParseContext->buffer if needed,
so ff_parse_close() must be called to free it.
