qemu_processpriv: Fix #error message
The point of qemu_processpriv.h file is to allow a small subset
of functions to be called from test suite but not elsewhere. This
is implemented by requiring everybody that includes the file to
define a macro. If not done so, an error is printed at compile
time. However, this error message contains a typo because it
mentions qemu_process_priv.h while the file is called
qemu_processpriv.h.

domain_cgroup: Fix a condition in virDomainCgroupConnectCgroup()
While parts of QEMU's CGroup code were moved under hypervisor
agnostic location (src/hypervisor/) a typo sneaked in. The
inspiration for virDomainCgroupConnectCgroup() comes from
qemuConnectCgroup(). The former is called upon reconnecting to a
running domain (after daemon restart). While the latter returned
early if the daemon was running unprivileged, the former returns
early if the daemon runs privileged. This is obviously wrong,
because root can set up CGroups.

Commit d73852c49962 moved the original QEMU-specific helpers to

as _SC_CLK_TCK.
To deal with that situation, commit d7c64453aa0e made the helpers
Linux-only and added stubs for other platforms that, when called,
would always fail with ENOSYS.
However the original helpers had been carefully written so that,
while they would only be able to produce useful output on Linux,
they would still succeed on the other Unix platforms where we
build the QEMU driver.

Docutils-0.17 also changed to use 'h2' for section heading instead of

Otherwise we do not know the pattern for rotated files.
For example for VM named "foo" we can not use "foo.log*" pattern to
remove rotated logs as we can have VM named "foo.log" with log
"foo.log.log". We can add extra check that filename does not end with
".log" but for VM "foo.log" we can have rotated log "foo.log.log.1". Ok
let's check we don't have "log" in filename part corresponging to * but
what if someone will use logrotate with "%Y.log-%m-%d" 'dateformat'
option. In this case the check will exclude proper rotated files.
Yes, the last example if quite artificial but it shows it is difficult
to find out correctly rotated files when rotated files pattern is not
known. Thus the above decision only to support case with virtlogd when
we know the pattern.
Another reason for not removing log files when logrotate is present is
that due to races some files can escape deletion. For example foo.log.3
will be rotated to foo.log.4 after removing function will read directory
files and thus foo.log.4 will not be deleted.
