This way, we avoid overwriting stream_index in the user's AVPacket
with a nonsense value.

this seems 1 cpu cycle slower even though we practically just remove code.
Speed loss seems caused by the merge of if(left_type), iam commiting this
anyway as i cant imagine this to be anything but compiler messup.

Most of the make builtin rules, which we do not need, are suffix rules,
and we use only new-style pattern rules.  Disabling suffix rules saves
some time when building on slow systems.

Also link avfiltergraph.o and graphparser.o against libavfilter, as it
uses them.

broken longer

about 5 cpu cycles slower in the local code but should be overall faster
due to reduced cache use. (my sample though has too few intra4x4 blocks
for this to be meassureable easily either way)

The code read/write code itself was 1 cycle faster, overall its
likely more due to cache effects

This is consistent with the metadata displaying in show_format() and
with the documentation.

opt_input_file(). More consistent and more clear, as "filename" can be
easily confused with the global "input_filename".

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.
