Patch for modified code.

We have found that the jpeg rtp payloader element will crash when we simulate random corruption in the JPEG byte stream.  We need the jpeg rtp payloader to be more robust to byte stream corruption so we have coded up additional checks around the number and the size of the quantization tables in the JPEG byte stream.

Thanks. commited an additional patch of mine that does some more checks and cleans up the other check.
