[libvirt PATCHv3 00/12] add virtiofs support (virtio-fs epopee)

[Ján Tomko]

https://bugzilla.redhat.com/show_bug.cgi?id=1694166
v1: https://www.redhat.com/archives/libvir-list/2019-November/msg00005.html
v2: https://www.redhat.com/archives/libvir-list/2020-January/msg00980.html

new in v3:
* renamed qemu.conf option
* removed cache-size since it was not yet merged in upstream QEMU
* use XPath for XML parsing
* separated virtiofsd options under the <binary> element [0]
* the binary path is now autodetected from vhost-user schemas
* log virtiofsd output into a file instead of syslog

[0] naming is hard
