/******************************************************************************
The general strategy of these tests (for interface levels 1 and 2) is
to create a dummy FLAC file with a known set of initial metadata
blocks, then keep a mirror locally of what we expect the metadata to be
after each operation. Then testing becomes a simple matter of running
a FLAC__StreamDecoder over the dummy file after each operation, comparing
the decoded metadata to what's in our local copy. If there are any
differences in the metadata, or the actual audio data is corrupted, we
will catch it while decoding.
