Given a Lzma compressed source buffer, this function retrieves the size of

Retrieves the size of the uncompressed buffer and the temporary scratch buffer

the size of the scratch buffer is returned ScratchSize, and RETURN_SUCCESS is returned.

field from the LZMA_HEADER_SIZE beginning bytes of the source data and output it as DestinationSize.

And ScratchSize is specific to the decompression implementation.

If SourceSize is less than LZMA_HEADER_SIZE, then ASSERT().

by Source and SourceSize is decompressed.
