[libvirt] [libvirt PATCH v3 0/4] Share cgroup code that is duplicated between QEMU and LXC

virLXCCgroupSetupBlkioTune() and qemuSetupBlkioCgroup() and virLXCCgroupSetupCpuTune() and qemuSetupCpuCgroup() are the most similar functions between QEMU and LXC code. Let's move their common code to virCgroup. Mind that the first two patches are basically preparing the ground for the changes introduced in the last two patches. I know that Pavel Hrdina suggested taking a different path[0] for this series but I do believe Michal's and Jano's points are valid, thus I've decided to just do the changes suggested by Michal (at least for now). [0]: https://www.redhat.com/archives/libvir-list/2018-September/msg00534.html changes since v1: - Michal Privoznik pointed out (as did the `make syntax-check` :-)) that we do want to keep src/util independently of the parsing code (thus, including "conf/domain_conf.h" in vircgroup.h is not the way to go). This has been solved now by partially following Michal's suggestion and splitting the structs and functions that would be use in the common code to new different files. changes since v2: - Fixed `make syntax-check` errors that I've missed before (didn't have cppi installed); - Created a new section in src/libvirt_private.syms to correctly export the virBlkioDeviceArrayClear symbol; - Removed a virlkio.c from libvirt_setuid_rpc_client_la__SOURCES (why did I add it there in the first place? ;-)) - Explicitly included virmem.h in qemu_{domain,command}.c. Although there's nothing enforcing it, I do believe it's a good practive that should be followed and I've checked with Andrea and Peter about doing that and both agreed with the approach.
