There are recommendations and limitations to the name of the
config blobs we need to follow [1].

We don't want users to change any value only add new blobs. This
means, that the name must have "opt/" prefix and at the same time
must not begin with "opt/ovmf" nor "opt/org.qemu" as these are
reserved for OVMF or QEMU respectively.

QEMU has -fw_cfg which allows users to tweak how firmware
configures itself and/or provide new configuration blobs.
Introduce new <sysinfo/> type "fwcfg" that will hold these
new blobs.

It's possible to either specify new value as a string or
provide a filename which contents then serve as the value.

Setting OEM strings for a domain was introduced in
v4.1.0-rc1~315. However, any application that wanted to use them
(e.g. to point to an URL where a config file is stored) had to
'dmidecode -u --oem-string N' (where N is index of the string).
Well, we can expose them under our <sysinfo/> XML and if the
domain is running Libvirt inside it can be obtained using
virConnectGetSysinfo() API.

Problem with custom dmidecode scripts is that they are hard to
modify, especially if we will want them to act differently based
on passed arguments. So far, we have two scripts which do no more
than 'cat $sysinfo' where $sysinfo is saved dmidecode output.

The virCommandSetDryRun() can be used to trick

Since we now use Cirrus CI for macOS jobs, we no longer need to

We use cirrus-run to trigger Cirrus CI jobs from GitLab CI jobs,
making it possible to extend our platform coverage to include
FreeBSD without having to maintain our own runners; additionally,
we'll be able to ditch Travis CI and, since results for Cirrus CI
jobs are reflected back to the GitLab CI jobs that triggered them,
we will be able to get all information from a single dashboard.

The FreeBSD and macOS job definitions can be improved further: for
example, we will want to enable caching to speed up builds, and
ultimately we should figure out a way to generate at least part of
them, notably the list of packages to be installed, using lcitool.
All of that will happen in later patches: for now, this is good
enough to start using Cirrus CI.

Juan Quintela noticed that when he restarted libvirt he was getting
extra iptables rules added by libvirt even though he didn't have any
libvirt networks that used iptables rules. It turns out this also
happens if the firewalld service is restarted. The extra rules are
just the private chains, and they're sometimes being added
unnecessarily because they are added separately in a global
networkPreReloadFirewallRules() that does the init if there are any
active networks, regardless of whether or not any of those networks
will actually add rules to the host firewall.

The fix is to change the check for "any active networks" to instead
check for "any active networks that add firewall rules".

(NB: although the timing seems suspicious, this isn't a new regression
caused by the recently pushed f5418b42 (which forces recreation of
private chains when firewalld is restarted); it was an existing bug
since iptables rules were first put into private chains, even after
commit c6cbe187 delayed creation of the private chains. The
implication is that any downstream based on v5.1.0 or later that cares
about these extraneous (but harmless) private chains would want to
backport this patch (along with the other two if they aren't already
there))

Until libvirt 2.5.0 we didn't have a real process for release
notes in place, and we just published the list of commits that
had made it into each release, dividing them into categories that
mostly matched the sections we use today. Those documents haven't
been relevant for years, but they're still in the git repository
and collectively take up almost 2 MiB of disk space.

If virDomainUpdateDeviceFlags() was used to update an <interface>, and
the interface type changed from type='network' where the network was
an unmanaged bridge (so actualType == bridge) to type='bridge'
(i.e. actualType *also* == bridge), the update would fail due to the
perceived change in type.

In practice it is okay to switch between any interface types that end
up using a tap device, since libvirt just needs to attach the device
to a new bridge. But in this case we were erroneously rejecting it due
to a conditional that was too restrictive. This is what the code was doing:

  if (old->type != new->type)
     [allow update]
  else
     if ((oldActual == bridge and newActual == network)
         || (oldActual == network and newActual == bridge)) {
         [allow update]
     else
         [error]

In the case described above though, old->type and new->type don't match,
but oldActual and newActual are both 'bridge', so we get an error.

This patch changes the inner conditional so that any combination of
'network' and 'bridge' for oldActual and newActual, since they both
use a tap device connected to a bridge.
