Michal Privoznik e82f99283d virSocketSendMsgWithFDs: Don't report errors, just set errno
Currently, virSocketSendMsgWithFDs() reports two errors:

1) if CMSG_FIRSTHDR() fails,
2) if sendmsg() fails.

Well, the latter sets an errno, so caller can just use
virReportSystemError(). And the former - it is very unlikely to
fail because memory for whole control message was allocated just
a few lines above.

The motivation is to unify behavior of virSocketSendMsgWithFDs()
and virSocketSendFD() because the latter is just a subset of the
former (will be addressed later).

Libvirt API for virtualization

Libvirt provides a portable, long term stable C API for managing the virtualization technologies provided by many operating systems. It includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER Hypervisor.

For some of these hypervisors, it provides a stateful management daemon which runs on the virtualization host allowing access to the API both by non-privileged local users and remote users.

Layered packages provide bindings of the libvirt C API into other languages including Python, Perl, PHP, Go, Java, OCaml, as well as mappings into object systems such as GObject, CIM and SNMP.
