4e06acbde4 Fixed a segfault in the DCA decoder with corrupted streams. 
It happens when the number of channels defined by DCAContext:acmod is lower
than DCAContext:prim_channels. In this case, dca_subsubframe() will call
qmf_32_subbands() using s->channel_order_tab[] entries equal to -1.

4784b0922f Do not read beyond end of input in EA-TGV. This should avoid FATE test #362 
result depending on uninitialized data.

FATE result may change for this test.

50ff78db01 RTSP muxer: Use a local copy of the AVPacket for sending to the chained muxer 
This way, we avoid overwriting stream_index in the user's AVPacket
with a nonsense value.

59b5370f02 Simplify code to set cbp_* 
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.

f3a572ca14 Disable suffix rules 
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.

5b0fb5244d Store intra4x4_pred_mode per row only. 
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)

c4a90caae2 aac: Keep decode_band_types() from eating all padding at the end of a buffer. 
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.
