Subject: Bug fixes in AAC decoder, AAC encoder, FDK library

Latest code drop from Fraunhofer:

* AAC-Decoder

   - Expanded AAC-LD/ELD decoder TNS max band tables to avoid wrong data
     access for sampling rates <22kHz and >48kHz.
     Modified file(s):
        libAACdec\src\aacdec_tns.cpp
        libAACdec\src\aac_rom.h
        libAACdec\src\aac_rom.cpp

  - Fixed ELD synthesis QMF filterbank scaling for downsampled SBR.
    Modified file(s):
        libFDK\src\qmf.cpp

* AAC-Encoder

  - Fixed bit rate limiting for lower limit as introduced in the Delivery 2012-05-11.
    Modified file(s):
        libAACenc\include\aacenc_lib.h
        libAACenc\src\aacenc.h
        libAACenc\src\aacenc.cpp
        libSBRenc\src\sbr_rom.h
        libSBRenc\src\sbr_rom.cpp

  - Allow negative prediction gain as meaning that there is no coding gain.
    Make use of scaleValueSaturate in gauss window calculation.
    Modified file(s):
        libAACenc\src\aacenc_tns.cpp

  - Added energy saturation to prevent overflow in short blocks.
    Modified file(s):
        libAACenc\src\grp_data.cpp

  - Perform scalefactor adaption in case quantized lines are out of valid range.
    Modified file(s):
        libAACenc\src\quantize.cpp

  - Interrupt quantization loop when no spectral data is available.
    Adjustments in bitreservoir adaption.
    Modified file(s):
        libAACenc\src\qc_main.cpp

  - Indroduced dynamic scaling in none missing harmonic energy lowering compensation.
    Modified file(s):
        libSBRenc\src\env_est.cpp

* FDK-Library

  - Fixed saturation for negative values in scaleValueSaturate.
    Modified file(s):
        libFDK\include\scale.h
