Potential memory leak for m_sdiSEIInFirstAU and m_maiSEIInFirstAU

[ksuehring]

In DecLib::xCheckPrefixSEIMessages() the variables are assigned

    m_sdiSEIInFirstAU = NULL;
    m_maiSEIInFirstAU = NULL;

and later

   m_sdiSEIInFirstAU = new SEIScalabilityDimensionInfo(*sdi);
   ...
   m_maiSEIInFirstAU = new SEIMultiviewAcquisitionInfo(*mai);

which initializes the variables to the SEI in the first AU of a CVS.

However when multiple CVS are included in the bitstream, the variables may be overwritten an the allocated memory will be lost.

Also there seems to be no delete when the program ends.
