   - Transport layer changes (config found) -> to be evaluated.
     Modified file(s):
        libMpegTPDec/include/tpdec_lib.h
        libMpegTPDec/src/tpdec_latm.h
        libMpegTPDec/src/version

   - Enable concealment state machine to skip states if the corresponding
     parameter is set to zero.
     Modified file(s):
        libAACdec/src/conceal.cpp

   - Add some more sanity checks to avoid segmentation faults especially when
     setting dynamic API params.

        libAACdec/src/aacdecoder.cpp

   - HCR decoder fix (remove warnings).
     Modified file(s):
