Anatol Belski 57e89b04f6 block: qcow: Refactor BackingFile for ownership based decomposition ...

Replace the clone based BackingFileOps trait with a BackingKind enum
so backing files can be decomposed into their concrete owned types.

BackingFile::new() for QCOW2 backings now calls parse_qcow() directly
instead of building a full QcowFile. Remove Clone for BackingFile and
QcowFile.

Prerequisite for the qcow_sync rewrite which decomposes a BackingFile
into a raw fd or QcowMetadata for lock free I/O.
