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

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.
