d53fe096e4 aacdec: Fix out of array writes (stack).
Set the element to channel vector (e2c_vec) size to be the maximum
number of aac channel elements. This makes it slightly larger than it
needs to be because CCEs are never mapped to output channel locations.

Also add a check that all input tags (legal or not) will fit.

12623a8026 vorbisdec: avoid invalid memory access
This fixes some invalid memory access caused later in the function
by res_chan[] not being set for all channels. This happens when a
channel doesn't appear a submap. This change simply returns a
decoder error when this situation is detected.

4ffe5e2aa5 huffyuv: add padding to classic (v1) huffman tables.
We slightly overread the input buffer, so we require
padding at the end of the buffer, as is documented in the
get_bits API. Without padding, we'll read uninitialized
data or beyond the end of the .rodata, which may crash.
