WARNING: pkgconfig variable 'cflags' not defined for dependency yajl.
which makes sense, because "cflags" is not one of the variables
reported by
$ pkg-config --print-variables yajl
and
$ pkg-config --variable=cflags yajl
doesn't work either.
The breakage was introduced when we switched from calling
pkg-config directly to using get_pkgconfig_variable() in 7.5.0
and, somehow, it went undetected until now.
Use "includedir", which is a proper pkg-config variable,
instead.

When -device is configured via JSON a bug [1] is triggered in qemu were
the DEVICE_DELETED event for the removal of the device frontend is no
longer delivered to libvirt. Without the DEVICE_DELETED event we don't
remove the corresponding entries in the VM XML.
Until qemu will be fixed we must stop using the JSON syntax for -device.
This patch removes the detection of the capability. The capability is
used only during startup of a fresh VM so we don't need to consider any
compaitibility steps for existing VMs.
For users who wish to use 'libvirt-7.9' and 'libvirt-7.10' with
'qemu-6.2' there are two possible workarounds:
- filter out the 'device.json' qemu capability '/etc/libvirt/qemu.conf':
capability_filters = [ "device.json" ]
- filter out the 'device.json' qemu capability via qemu namespace XML:
<domain type='kvm' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'>
[...]
<qemu:capabilities>
<qemu:del capability='device.json'/>
</qemu:capabilities>
</domain>
We must never again use the same capability name as we are now
instructing users to filter it as a workaround so once qemu is fixed
we'll need to pick a new capability value for it.

We don't usually provide manual pages for internal tools,
but in the case of virt-ssh-helper the command is installed
inside the default $PATH and so it's likely that the user
will stumble upon it by using the shell's completion feature
when invoking another virt-* command, which makes it a good
idea to provide at least a minimal manual page.

Until now we did 2 weird things when inserting the qemuCaps used for
individual test cases into the capability cache:
1) we inserted the same caps for all emulators
2) we always (expensively) copied them
Now when real capabilities are used we don't touch them at all just
simply inser them. This allows us one big optimization, by trading a
copy for just a virObjectRef as we can borrow the caps object to the
cache.
For fake caps we still copy them as we insert the fake machine types
into them, but second big optimization is to insert the capabilities
only for the architecture they belong to.
Additionally this commit also ensures that all other entries in the
cache for the binary are poisoned by empty caps so that it's obvious
that the test is doing the right thing.
Apart from this making actually more sense this shaves off more than 40%
of runtime from qemuxml2argvtest.

As demonstrated by the qemuxml2xmltest DO_TEST_CAPS_LATEST data based on
the 'x86-kvm-32-on-64' test case the post parse CPU selection code which
fills in the CPU into the definition does not have exactly the same
logic as we used to have when the cpu model was picked when formatting
the commandline.
Change the qemuxml2argv test to use DO_TEST_CAPS_LATEST too as it
doesn't really make sense to test this on fake data.
In addition to 'latest' versions, this also adds second invocation
locked to qemu-4.1.0 which demonstrates the old behaviour.

Fake capabilities are inserted twice, as in a few tests the architecture
is not present in the XML (testing filling in of the architecture).
Since we already know which architecture will be picked we don't need to
be adding the capabilities twice.
This doesn't impact the tests as they use the same approach to determine
the default arch.

In a few places (e.g. device attach/detach/update) we are given a
device XML, parse it but then need a copy of parsed data so that
the original can be passed to function handling the request over
inactive XML and the copy is then passed to function handling the
operation over live XML. Note, both functions consume passed
device on success, hence the need for copy.
The problem is in combination of how the copy is obtained and
where is passed. The copy is done by calling
virDomainDeviceDefCopy() which does only inactive copy, i.e. no
live information is copied over (e.g. no aliases).
Then, this copy (inactive XML effectively) is passed to function
handling live part of the operation (e.g.
qemuDomainUpdateDeviceLive()) and the definition containing all
the juicy, live bits is passed to function handling inactive part
of the operation (e.g. qemuDomainUpdateDeviceConfig()).
This is rather incorrect, and XML copies should be passed to
their respective functions.

And make callers check the return value as well. This helps error out early for
invalid environment variables.
That is desirable because it could lead to deadlocks. This can happen when
resetting logging after fork() reports translated errors because gettext
functions are not reentrant. Well, it is not limited to resetting logging after
fork(), it can be any translation at that phase, but parsing environment
variables is easy to make fail on purpose to show the result, it can also happen
just due to a typo.
Before this commit it is possible to deadlock the daemon on startup
with something like:
LIBVIRT_LOG_FILTERS='1:*' LIBVIRT_LOG_OUTPUTS=1:stdout libvirtd
where filters are used to enable more logging and hence make the race less rare
and outputs are set to invalid
Combined with the previous patches this changes
the following from:
...
<deadlock>
to:
...
libvirtd: initialisation failed
