Anatol Belski b3922dbd2c block: qcow: Add raw backing file support ...

Add support for raw backing files in addition to qcow2 backing
files. This enables QCOW2 overlays to use raw images as their
backing store.

The backing file format is auto-detected when not specified,
using the existing detect_image_type() function.

Add backing_file_format field to QcowHeader to store the format
type, which will be populated from header extensions by a
subsequent patch.

Modify new_from_backing() to accept a backing_format parameter,
consolidating support for both raw and qcow2 backing files in a
single function. The backing_file_size parameter allows overlay
creation without opening the backing file multiple times.
