Subject: Decoder stability, sanity checks improvements

* AAC-Decoder

   - Improved PCE handling for saver (re-)configuration and metadata processing.
     Modified file(s):
        libAACdec/src/aacdecoder.cpp
        libAACdec/src/aacdecoder_lib.cpp

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

   - 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.
     Modified file(s):
        libAACdec/src/aacdecoder_lib.cpp

   - Fix to do a fail-safe initialization of IMDCT for all channels even with
     corrupt streams.
     Modified file(s):
        libAACdec/src/aacdecoder.cpp

   - HCR decoder fix (remove warnings).
     Modified file(s):
        libAACdec/src/block.cpp

   - Fix border calculation in SBR decoder's LPP transposer patch determination.
     Modified file(s):
        libSBRdec/src/env_dec.cpp
