There's no reason why the virNetServerClientDispatchRead method needs to
acquire an extra reference on the "client" object. An extra reference is
only needed if the registered dispatch callback is going to keep hold of
the "client" for work in the background. Thus we can push reference
acquisition into virNetServerDispatchNewMessage.

This function was introduced in commit 41f5c2ca27 as a way
to probe the same property for multiple devices at once.
Although the resulting representation is very compact, it
doesn't provide any extra features compared to the existing
virQEMUCapsProcessStringFlags() mechanism, which is already
used for pretty much all device properties.
Drop the custom function and datatypes and start using the
standard ones instead.
Note that, in theory, the end result is not identical
because we're no longer probing properties for
virtio-serial-pci
virtio-9p-pci
virtio-rng-pci
virtio-input-host-pci
virtio-keyboard-pci
virtio-mouse-pci
virtio-tablet-pci
However, chances of any of those devices being compiled
into a QEMU binary where
virtio-balloon-pci
virtio-blk-pci
virtio-scsi-pci
virtio-net-pci
virtio-gpu-pci
are compiled out are slim enough that it doesn't make any
difference in practice, as the lack of test suite churn
shows.

In some cases, we are probing multiple devices for the same
property and setting the corresponding capability if it's
found on any of the devices: when that happens, we can quit
early after finding the first property and avoiding a bunch
of string comparisons.

Commit 4ae59411fa introduced the ability to make probing for
device properties conditional on a capability being set, but
didn't extend the use of this feature to existing devices.
This commit does the last bit of work, which results in a lot
of pointless QMP chatter no longer happening and our test suite
shrinking a fair bit.

In certain cases a xml contains paths that do not yet exist, but
are valid as qemu will create them later on - for example
vhostuser mode=server sockets.
In any such cases so far the check to virFileExists failed and due to
that the paths stayed non-resolved in regard to symlinks.
But for apparmor those non-resolved rules are non functional as they
are evaluated after resolving any symlinks.
Therefore for non-existent files and partially non-existent paths
resolve as much as possible to get valid rules.
Example:
<interface type='vhostuser'>
<model type='virtio'/>
<source type='unix' path='/var/run/symlinknet' mode='server'/>
</interface>
Got rendered as:
"/var/run/symlinknet" rw,
But correct with "/var/run" being a symlink to "/run" is:
"/run/symlinknet" rw,

When commit 3545cbef moved the sysfs attribute reading logic from
_udev.c module to virmdev.c, it had to replace our udev read wrappers
with the ones available from virfile.c. The problem is that the original
logic worked correctly with udev read wrappers which don't return an
error code for a missing attribute, virfile.c readers however - not so
much. Therefore add another parameter to the macro, so we can again
accept the fact that optional attributes may be missing.

If the user tries to define a domain that has
<controller type='usb' model='none'/>
and also some USB devices, we report an error:
error: internal error: No free USB ports
Which is technically still correct for a domain with no USB ports.
Change it to:
USB is disabled for this domain, but USB devices are present in the domain XML

When trying to destroy a domain (e.g. because we've seen EOF on
the monitor) we try to acquire QEMU_JOB_DESTROY. However, if
max_queued is set in qemu.conf this may fail and since our code
doesn't count on that we will still report domain as active even
though the qemu process is long gone. More specifically, if we've
seen EOF on the monitor, qemuProcessHandleMonitorEOF() is called
which sends MONITOR_EOF job to the event worker pool and
unregisters monitor from the event loop. The worker pool calls
processMonitorEOFEvent() which tries to set job which may fail
due to the limit as described above.

When generating certificates we rely on GNUTLS' built-in default setup
for the ciphers used in the certs. We then currently run with the distro
specific TLS priority setup which can be much stronger, to the extent
that the certificates we generate are considered untrustworthy. We don't
care about the quality of the ciphers we use in the test suite, so just
force the priority to "NORMAL" which should ensure our certs are
accepted by GNUTLS.

The homebrew formula's ignored Python PEP-0394 recommendations and
changed the plain python binary in /usr/local/bin to point to Python 3
instead of Python 2. Python 2 is not even installed into a location that
is in $PATH by default anymore. The homebrew packages print a message
to stderr claiming to provide a way to fix this
[quote]
This formula installs a python2 executable to /usr/local/opt/python@2/bin
If you wish to have this formula's python executable in your PATH then add
the following to ~/.bash_profile:
export PATH="/usr/local/opt/python@2/libexec/bin:$PATH"
[/quote]
When trying to update $PATH are suggested we find out this message is a
lie and /usr/local/opt/python@2 does not even exist, instead Python
seems to end up in /usr/local/Cellar/python@2/2.7.14_1
Rather than hardcoding this version specific directory in our travis
config, we change to run "brew link --force python@2", to make it create
symlinks in /usr/local/bin for the python2 binary.
The original change triggering this problem was
https://github.com/Homebrew/homebrew-core/pull/24604#issue-171653084
There are countless bug reports against homebrew-core that are closed
without fixes, so it seems they are determined to ignore the Python
PEP 0394 recommendations on this.

We allow the postParse callbacks to fail for some reasons (missing
emulator binary) when parsing the configs from /etc/libvirt.
In that case, def->postParseFailed is set to true and the post
parse callbacks are re-executed on domain startup.
However this bool was only set when virDomainDefPostParse was called
with the ALLOW_POST_PARSE_FAIL flag set. If the callback failed
again on domain startup, the bool would be reset and subsequent
startups would not attempt to reexecute the callback.
