* Revert "[Bug 2533] New: Extreme space inefficiency importing silence from an AUP file"... ... It did not fix the symptoms. Using a zero blob only gives temporary in-memory space efficiency when adding a row to the database, not space savings in the file. This reverts commit d9047dfd254ecf92c0770c0cbda62a238c2fdd29. * Remove unused SampleBlockFactory::Get * Eliminate some repetition and magic numbers * Lower some common steps into GetSummary(); removed unused argument * mSummary256Bytes and mSummary64kBytes not needed after initialization * Satisfy sample and summary requests for silent blocks without using db
