Main idea was to split the disk code since I'll be changing it later but
as I was at it I refactored everything.
Peter Krempa (5):
qemu: domain: Extract disk post parse code into a function
qemu: domain: Extract network device def post parse code
qemu: domain: Extract video device def post parse code
qemu: domain: Extract panic device def post parse code
qemu: domain: Use typecasted enum in qemuDomainDeviceDefPostParse

New subject: [libvirt] [PATCH 1/5] qemu: domain: Extract disk post parse code into a function
Later on, more stuff will be added so prevent the main function growing
out of control.
