Make possible to activate adaptive AGC2 in the APM.

Browse Source 
We update the configuration settings for AGC2. We also update their
effects. Now, 'gain_controller2.enable=true' means 'first run Adaptive
AGC2; then run AGC2 limiter'.

Previously, only the AGC2 limiter was implemented. To run that, one
had to set both 'gain_controller2.enable=true' and
'gain_controller2.enable_limiter=true'.

This setting also enables adaptive AGC2 in the test tool 'audioproc_f'.
