Re: [PATCH 0/7] qemu XML testing improvements, part 3 - xmlout->xmlout testing and fixes

This series depends on the 'part 2' with cover letter's subject: [PATCH 00/23] qemu XML testing improvements, part 2 - enforcement of xml->xml testing both this along with the rebased prerequisite series can be fetched from: git fetch https://gitlab.com/pipo.sk/libvirt.git test-improvements-3 The main goal of part 3 is to add testing based on parsing of the libvirt-formatted files from tests/qemuxml2xmloutdata and formatting them back, and checking that they are identical. By adding this testing multiple problems in code auto-adding information was discovered. Peter Krempa (7): virDomainDefMaybeAddVirtioSerialController: Reformat hard to read linebreaks conf: domain: Insert auto-added controllers in same order as in XML parser virDomainAssignControllerIndexes: Ensure controller ordering after assigning indexes qemu: Move 'shmem' device size validation to qemu_validate qemuDomainAssignPCIAddresses: Assign extension addresses when auto-assigning PCI address virDomainDefAddConsoleCompat: Fix numbering of console targets after modification qemuxml2conftest: Test re-parsing of formatted XML
