When a backing chain element specifies a parent in a format not known to libvirt
we'd fail to start the VM as the chain would appear broken.
To prevent this happening introduce a new disk type to collect
unknow format specs and avoid startup failures with such disk type.
Peter Krempa (5):
util: storage: Convert disk locality check to switch statement
conf: Introduce raw disk string passthrough
conf: Mark backing chain ending with "raw" volume as broken
tests: Add tests for disk type 'raw'
utils: storage: Fall back to "raw" disk on backing store parse
failure
