[libvirt] [PATCH v6 00/11] qemu: Validate PCI controller options
Applies cleanly on top of 11819aee65b8ea71860526f529d86ab646b9cd1f. Patches 2/11 and 4/11 are the only ones missing R-bs, everything else hasn't been significantly altered since the previous respin. Changes from [v5]: * patch 1 has been pushed; * add virReportController*() functions to cut down on redundant error reporting, as suggested by laine; * report index and modelName along with model in error messages. Changes from [v4]: * patch 1/12 is new; * use virReportEnumRangeError(), as suggested by laine. Changes from [v3]: * don't introduce new test cases that won't be able to provide full test coverage anyway, as suggested by laine. Changes from [v2]: * replace the old implementation bit by bit using a clever trick suggested by pkrempa; * don't move QEMU capability validation; * add a default: label to all switch statements as recommended by danpb. Changes from [v1]: * error out instead of silently accept invalid options; * shave quite a lot of yaks.

The existing function is renamed and called from the new one, so that even while we're in the process of implementing new checks all the existing ones will be performed.
