This CL adds the ability in audioproc_f and unpack_aecdump to:
-Clearly identify the Init events and when those occur.
-Optionally only process a specific Init section of an aecdump.
-Optionally selectively turn on dumping of internal data for a
specific init section, and a specific time interval.
-Optionally let unpack_aecdump produce file names based on inits.
