This patch adds support for PPM marker for JPEG2000
decoder. It allows the samples p1_03.j2k and p1_05.j2k
to be decoded.

The codeblock decoder checks whether the mqc decoder
has decoded the right number of bytes. However, this
check does not account for the fact that the mqc encoder's
flush routine adds 2 bytes of data which does not have to be
read by the decoder. The check is modified to
