7ba0cedbfe rpza: Fix a buffer size check
We read 2 bytes for 15 out of 16 pixels, therefore we need to
have at least 30 bytes, not 16.

aa0dd52434 xxan: Disallow odd width
Decoded data is always written in pairs within this decoder.
This fixes writes out of bounds.

9fb0de86b4 pcx: Consume the whole packet if giving up due to missing palette
Previously, we returned 0, meaning successful decoding but 0
bytes consumed, leading to an infinite loop.

a81cad8f86 pngdec: Stop trying to decode once inflate returns Z_STREAM_END
If the input buffer contains more data after the deflate stream,
the loop previously left running infinitely, with inflate returning

d87ff55502 Remove an incorrect and unneeded assert in the amr demuxer.
Asserting a specific codec is not correct since libavformat
allows forcing a codec, an equivalent check is in the
following line.

or a 16x16 VP8 file with -fflags +emu_edge.
