572ce352da docs: stop using syntax highlighting for man page code blocks
Some versions of the rst2man convertor are buggy failing to
cope with syntax highlighting in code blocks.

This isn't something we really need for the man page code
blocks, so we can just delete the highlighting directive.

766c8ae963 Revert "qemu: directly create virResctrlInfo ignoring capabilities"
This reverts commit 7be5fe66cd.

This commit broke resctrl, because it missed the fact that the
virResctrlInfoGetCache() has side-effects causing it to actually
change the virResctrlInfo parameter, not merely get data from
it.

This code will need some refactoring before we can try separating
it from virCapabilities again.

d75f865fb9 qemu: fix concurrency crash bug in snapshot revert
This commit aims to fix

https://bugzilla.redhat.com/show_bug.cgi?id=1610207

The cause was apparently incorrect handling of jobs in snapshot
revert code which allowed a thread executing snapshot delete to
begin job while snapshot revert was still running on another
thread. The snapshot delete thread then waited on a condition
variable in qemuMonitorSend() while the revert thread finished,
changing (and effectively corrupting) the qemuMonitor structure
under the delete thread which led to its crash.

The incorrect handling of jobs in revert code was due to the fact
that although qemuDomainRevertToSnapshot() correctly begins a job
at the start, the job was implicitly ended when qemuProcessStop()
was called because the job lives in the QEMU driver's private
data (qemuDomainObjPrivate) that was purged during
qemuProcessStop().

This fix prevents qemuProcessStop() from clearing jobs as the
idea of qemuProcessStop() clearing jobs seems wrong in the first
place. It was (inadvertently) introduced in commit
888aa4b6b9, which is effectively reverted by
the second hunk of this commit. To preserve the desired effects
of the faulty commit, the first hunk is included as suggested by
Michal.

1902356231 qemu: keep capabilities when running QEMU as root
When QEMU uid/gid is set to non-root this is pointless as if we just
used a regular setuid/setgid call, the process will have all its
capabilities cleared anyway by the kernel.

When QEMU uid/gid is set to root, this is almost (always?) never
what people actually want. People make QEMU run as root in order
to access some privileged resource that libvirt doesn't support
yet and this often requires capabilities. As a result they have
to go find the qemu.conf param to turn this off. This is not
viable for libguestfs - they want to control everything via the
XML security label to request running as root regardless of the
qemu.conf settings for user/group.

Clearing capabilities was implemented originally because there
was a proposal in Fedora to change permissions such that root,
with no capabilities would not be able to compromise the system.
ie a locked down root account. This never went anywhere though,
and as a result clearing capabilities when running as root does
not really get us any security benefit AFAICT. The root user
can easily do something like create a cronjob, which will then
faithfully be run with full capabilities, trivially bypassing
the restriction we place.

IOW, our clearing of capabilities is both useless from a security
POV, and breaks valid use cases when people need to run as root.

This removes the clear_emulator_capabilities configuration
option from qemu.conf, and always runs QEMU with capabilities
when root.  The behaviour when non-root is unchanged.

40780d1a4c docs: introduce rst2man as a mandatory tool for building docs
The rst2man tool is provided by python docutils, and as the name
suggests, it converts RST documents into man pages.

The intention is that our current POD docs will be converted to
RST format, allowing one more use of Perl to be eliminated from
libvirt.

The manual pages will now all be kept in the docs/manpages/ directory,
which enables us to include the man pages in the published website.
This is good for people searching for libvirt man pages online as it
makes it more likely google will send them to the libvirt.org instead
of some random third party man page site with outdated content.
