Encoder ELD auto configurator
* AAC-Encoder
- Introduce ELD auto configurator to get predefined configuration at given
bitrate and sampling rate. The configurator selects SBR on/off and if SBR
enabled distinguishes between dualrate and downsampled SBR. In default
configuration the ELD auto configurator is enabled.

Encoder explicit signaling
* AAC-Encoder
- Revise explicit signaling method which is required for downsampled SBR.
The parameter is optional and default configuration is implicit signaling
for dualrate SBR as before. In case of downsampled SBR and HE-AAC explicit
signaling is configured as default.
