  1. Optimize digest computation for uncompressed layers 

    When the caller provides neither OriginalDigest nor
UncompressedDigest, only digest the layer once.

  2. Add LayerOptions.OriginalSize 

    This allows us to correctly set (CompresedDigest, CompressedSize)
when copying data from another layer; in that case we don't have the
compressed data, so computing the size from compressedCounter
sets an incorrect value.
