We have always considered "migrate_cancel" QMP command to return after
successfully cancelling the migration. But this is no longer true (to be
honest I'm not sure it ever was) as it just changes the migration state
to "cancelling". In most cases the migration is canceled pretty quickly
and we don't really notice anything, but sometimes it takes so long we
even get to clearing migration capabilities before the migration is
actually canceled, which fails as capabilities can only be changed when
no migration is running. So to avoid this issue, we can wait for the
migration to be really canceled after sending migrate_cancel. The only
place where we don't need synchronous behavior is when we're cancelling
migration on user's request while it is actively watched by another
thread.

However, I forgot to swap the arguments in
qemuDomainGetStatsCpuProc() which leads to userTime and sysTime

The filesystem type magic constant was added for the 'quobyte' shared
filesystem in commit 451094bd15 but is present neither in the kernel
sources nor in coreutils which we've historically used as source of

Since the code dealing with FUSE-based filesystems doesn't need the
constant we can remove it and the now-dead check for it.

For domains started under session URI, we don't set up CGroups
(well, how could we since we're not running as root anyways).
Nevertheless, fetching CPU statistics exits early because of
lacking cpuacct controller. But with recent extension to
virProcessGetStatInfo() we can get the values we need from the
proc filesystem. Implement the fallback for the session URI as
some of virt tools rely on cpu.* stats to be reported (virt-top,
virt-manager).
