184749691f qemu_migration_params: Replace qemuMigrationParamTypes array
We will need to annotate individual parameters a bit more than just
noting their type. Let's introduce qemuMigrationParamInfo replacing
simple qemuMigrationParamTypes with an array of structs.

f9dcc01a0f qemu_migration: Avoid mem.hard_limit > 0 check
My original commit v8.4.0-288-gf01fc4d119 accidentally forgot to fix
both instances of the same problem. While it fixed the destination side
of migration, the source one remained broken.

However, that commit was also wrong in saying the issue could have
caused unlimited memory locking to be allowed for QEMU when RDMA
migration was used. It could not, because the code would refuse to even
think about starting RDMA migration if hard_limit was not set. But
avoiding the "mem.hard_limit > 0" check is useful anyway.

f3f877cfa6 qemu_hotplug: Don't skip cleanup in qemuDomainAttachNetDevice()
Introduced in v8.4.0-rc1~183 but the first real problem
introduced in v8.4.0-rc1~170, there's a
qemuBuildInterfaceConnect() call inside of
qemuDomainAttachNetDevice(). If the former fails, then the
function is immediately returned from instead of jumping onto the
cleanup label. This is crucial, because at this point the domain
definition contains 'borrowed' net definition, which is then
freed, since an error was met. The domain definition is then left
with a dangling pointer which leads to all sorts of different
crashes.

0ba3870406 API: Remove internal impl detail from VIR_DOMAIN_IOTHREAD_THREAD_POOL_{MIN,MAX} description
When introducing VIR_DOMAIN_IOTHREAD_THREAD_POOL_MIN and
VIR_DOMAIN_IOTHREAD_THREAD_POOL_MAX typed parameters, I've made a
shortcut. Since at the monitor level these two are set in two
separate calls and minimum has to be always smaller than maximum
(or equal to it), it may happen that one of the values we want to
set violates this restriction. So I've put a little note in the
public API description warning users about this.

However, the proper solution is to have a logic that checks the
current values and based on that set either minimum or maximum
value first. But until we get there, remove that note from the
public API before it gets released.

f01fc4d119 qemu_migration: Don't set unlimited memlock limit for RDMA

that we know how big memory locking limit should be set for the domain

the default hard_limit value from 0 to
VIR_DOMAIN_MEMORY_PARAM_UNLIMITED) we were actually setting memlock
limit to unlimited if hard_limit was not set.

This preserves the error around the entire teardown process, similar

dae16374dd nwfilter: spawn thread for reloading on firewalld trigger
When firewalld is restarted or has its rules reloaded, we trigger a
reload of the nwfilter driver. This is done directly in the main
event loop thread which is a bad idea.

In a previous commit we fixed a actual deadlock problem with the
virStateReload API, when triggered from SIGHUP:

commit 33c6eb9689
Author: Jim Fehlig <jfehlig@suse.com>
Date:   Thu Mar 8 15:04:48 2018 -0700

    libvirtd: fix potential deadlock when reloading

The same deadlock problem previously existed with the firewalld reload
trigger, however, today it is not quite so series. The QEMU driver uses
a private event thread for each VM, so the particular deadlock would
not occur. None the less during the time the filters are reloading all
use of the event loop is blocked, which prevents APIs being serviced.

8603b3d76c tools: add '--xpath EXPRESSION --wrap' args to all dumpxml commands
While you can chain the virsh output up to a later 'xmllint' or 'xpath'
command, integrating it into virsh avoids needs for installing extra
binaries which we've often found to be missing on production installs
of libvirt. It also gives better response if the initial virsh command
hits an error, as you don't get an aborted pipeline.

    $ virsh pool-dumpxml --xpath //permissions default
    <permissions>
      <mode>0711</mode>
      <owner>1000</owner>
      <group>1000</group>
      <label>unconfined_u:object_r:svirt_home_t:s0</label>
    </permissions>

If multiple nodes match, they are emitted individually:

    $ virsh dumpxml --xpath '//devices/*/address[@type="pci"]' --wrap demo
    <address type="pci" domain="0x0000" bus="0x05" slot="0x00" function="0x0"/>
    <address type="pci" domain="0x0000" bus="0x03" slot="0x00" function="0x0"/>
    ...snip...
    <address type="pci" domain="0x0000" bus="0x00" slot="0x02" function="0x0" multifunction="on"/>
    <address type="pci" domain="0x0000" bus="0x07" slot="0x00" function="0x0"/>

but if intending to post-process the output further, the results
can be wrapped in a parent node

    $ virsh dumpxml --xpath '//devices/*/address[@type="pci"]' --wrap demo
    <nodes>
      <address type="pci" domain="0x0000" bus="0x05" slot="0x00" function="0x0"/>
      <address type="pci" domain="0x0000" bus="0x03" slot="0x00" function="0x0"/>
      ...snip...

812edc95a3 conf: cpu: Add <signature family=X model=X stepping=X/>
Internally we already collect x86 host family + model + stepping
numeric values. This exposed them in capabilities CPU output.
Example:

$ sudo virsh capabilities | grep -A1 -B1 signature
      <microcode version='240'/>
      <signature family='6' model='94' stepping='3'/>
      <counter name='tsc' frequency='3408010000' scaling='no'/>

Users need to know these values to calculate an expected.
SEV-ES/SEV-SNP launch measurement.
