SBR/AAC encoder updates, code clean up

* SBR-Encoder

   - Prevent noise level overflow in noise floor detection.
   - Saturate threshold calculation in transient detection.
     Modified file(s):
        libSBRenc/src/nf_est.cpp
        libSBRenc/src/sbr_encoder.cpp
        libSBRenc/src/tran_det.cpp

* AAC-Encoder

   - Expand input data range of GetInvInt() function. There was an encoder
     assert observed in non-default bitrate configuration.
     Modified file(s):
        libAACenc/src/aacenc_lib.cpp
        libAACenc/src/intensity.cpp
        libFDK/include/fixpoint_math.h
        libFDK/src/FDK_core.cpp
        libFDK/src/FDK_tools_rom.cpp

   - Make sure that the encoder is stable with regard to very low audio bandwidth
     confguration parameter value.
   - Fix lowdelay blending for low audio bandwidth.

        libAACenc/src/adj_thr.cpp
        libAACenc/src/psy_configuration.cpp
        libAACenc/src/psy_main.cpp

   - Disable pseudo surround flag in case metadata matrix mixdown index is
     present in program config element.
     Modified file(s):
        libAACenc/src/aacenc_lib.cpp

   - Enable variable bitrate mode in encoder api.
   - Add AACENC_PEAK_BITRATE parameter to encoder api.
   - Add AACENC_AUDIOMUXVER parameter to encoder api.

* FDK-Sources

   - Code clean up. Remove unneeded pseudo audio object types and transport types.
