Sample block cleanups (#657)

Browse Source 
* 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 d9047dfd25.

* 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
