[libvirt PATCH v4 0/4] Add support for QEMU's fmode and dmode
This is the latest set of patches to expose QEMU's fmode and dmode functionality. I hopefully split these up correctly per Peter Krempa's guidance. I debated where to implement the fmode/dmode value validation and ultimately decided on domain_conf.c rather than qemu_validate.c. My reasoning being that it is essentially enforcing the schema rather than performing QEMU-specific validation.

The QEMU 9pfs 'fmode' and 'dmode' options have existed since QEMU 2.10. Probe QEMU's command line set to check whether these options are available, and if yes, enable this new QEMU_CAPS_FSDEV_CREATEMODE capability on libvirt side.
