1a5c864e9f util: Introduce virAcpi module
The aim of this new module is to contain code that's parsing ACPI
tables. For now, only parsing of IORT table is implemented (it's
ARM specific table). And since we only need to check whether the
table contains SMMU record, the code is very simplified.
I've followed the specification published here:

69eeef5dfb logging: add log cleanup for obsolete domains
Before, logs from deleted machines have been piling up, since there were
no garbage collection mechanism. Now, virtlogd can be configured to
periodically scan the log folder for orphan logs with no recent modifications
and delete it.

A single chain of recent and rotated logs is deleted in a single transaction.

a56f0168d5 qemu: hook up passt config to qemu domains
This consists of (1) adding the necessary args to the qemu commandline
netdev option, and (2) starting a passt process prior to starting
qemu, and making sure that it is terminated when it's no longer
needed. Under normal circumstances, passt will terminate itself as
soon as qemu closes its socket, but in case of some error where qemu
is never started, or fails to startup completely, we need to terminate
passt manually.

The following patches move job object as a member into the domain

defined) needs to import the file with the job object.

It makes sense to move jobs to the same level as the domain_conf:
into src/conf/

b7b949d30c network: create separate config object for virNetworkDriverState
Similar to the other drivers, virNetworkDriverState now has a
virObject-derived object called virNetworkDriverConfig which is used
for config items.

As a starting point, the directory paths used by the network driver
are moved there (again, parallelling what is done for other drivers).

Using items in virNetworkDriverConfig is (yes, again) similar to using
items in the other drivers' config - anything in the config object is
immutable (once initialized), so the state object only needs to be
locked while getting a reference to the config object, and then the
members of the config object can be safely used until the config
object is unrefed.

d9916c3519 conf: Separate domain post parse code into domain_postparse.c
The domain post parse functions currently live in domain_conf.c
which thus grows always larger. Mimic what we've done for the
validation code and move the post parse code into a separate
file: domain_postparse.c.

I've started by moving every function with PostParse in its name
into the new file and then compile hunting for helper functions
only to move them as well.

In the end, I've moved virDomainDefPostParse symbol in
libvirt_private.syms into a new section. And while
virDomainDeviceDefPostParseOne() is made 'public' in
domain_postparse.h too, I'm not exporting it because it has no
caller outside src/conf/ and it's unlikely it ever will.

689beaa47c backup: Implement virsh support for checkpoints
Introduce a bunch of new virsh commands for managing checkpoints in
isolation. More commands are needed for performing incremental
backups, but these commands were easy to implement by modeling heavily
after virsh-snapshot.c. There is no need for checkpoint-revert or
checkpoint-current since those snapshot APIs have no checkpoint
counterpart.  Similarly, it is not necessary to change which
checkpoint is current when redefining from XML, since until we
integrate checkpoints with snapshots, there is only a linear chain
(and you can deduce the current checkpoint by instead using
'checkpoint-list --leaves').  Other aspects of checkpoint-list are
also a bit simpler than the snapshot counterpart, in part because we
don't have to cater to back-compat to older API.

Upcoming patches will test these interfaces once the test driver
supports checkpoints.

1a4df34a0f backup: Parse and output checkpoint XML
Add a new file checkpoint_conf.c that performs the translation to and
from new XML describing a checkpoint. The code shares a common base
class with snapshots, since a checkpoint similarly represents the
domain state at a moment in time. Add some basic testing of round trip
XML handling through the new code.

Of note - this code intentionally differs from snapshots in that XML
schema validation is unconditional, rather than based on a public API
flag.  We have many existing interfaces that still need to add a flag
for opt-in schema validation, but those interfaces have existing
clients that may not have been producing strictly-compliant XML, or we
may still uncover bugs where our RNG grammar is inconsistent with our
code (where omitting the opt-in flag allows existing apps to keep
working while waiting for an RNG patch).  But since checkpoints are
brand-new, it's easier to ensure the code matches the schema by always
using the schema.  If needed, a later patch could extend the API and
add a flag to turn on to request schema validation, rather than having
it forced (possibly just the validation of the <domain> sub-element
during REDEFINE) - but if a user encounters XML that looks like it
should be good but fails to validate with our RNG schema, they would
either have to upgrade to a new libvirt that adds the new flag, or
upgrade to a new libvirt that fixes the RNG schema, which implies
adding such a flag won't help much.

Also, the redefine flag requires the <domain> sub-element to be
present, rather than catering to historical back-compat to older
versions.

0d44788fc3 backup: Introduce virDomainCheckpoint APIs
Introduce a bunch of new public APIs related to backup checkpoints.
Checkpoints are modeled heavily after virDomainSnapshotPtr (both
represent a point in time of the guest), although a snapshot exists
with the intent of rolling back to that state, while a checkpoint
exists to make it possible to create an incremental backup at a later
time.  We may have a future hypervisor that can completely manage
checkpoints without libvirt metadata, but the first two planned
hypervisors (qemu and test) both always use libvirt for tracking
metadata relations between checkpoints, so for now, I've deferred
the counterpart of virDomainSnapshotHasMetadata for a separate
API addition at a later date if there is ever a need for it.

Note that until we allow snapshots and checkpoints to exist
simultaneously on the same domain (although the actual prevention of
this will be in a separate patch for the sake of an easier revert down
the road), that it is not possible to branch out to create more than
one checkpoint child to a given parent, although it may become
possible later when we revert to a snapshot that coincides with a
checkpoint.  This also means that for now, the decision of which
checkpoint becomes the parent of a newly created one is the only
checkpoint with no child (so while there are APIs for dealing with a
current snapshot, we do not need those for checkpoints).  We may end
up exposing a notion of a current checkpoint later, but it's easier to
add stuff when proven needed than to blindly support it now and wish
we hadn't exposed it.

The following map shows the API relations to snapshots, with new APIs
on the right:

Operate on a domain object to create/redefine a child:
virDomainSnapshotCreateXML          virDomainCheckpointCreateXML

Operate on a child object for lifetime management:
virDomainSnapshotDelete             virDomainCheckpointDelete
virDomainSnapshotFree               virDomainCheckpointFree
virDomainSnapshotRef                virDomainCheckpointRef

Operate on a child object to learn more about it:
virDomainSnapshotGetXMLDesc         virDomainCheckpointGetXMLDesc
virDomainSnapshotGetConnect         virDomainCheckpointGetConnect
virDomainSnapshotGetDomain          virDomainCheckpointGetDomain
virDomainSnapshotGetName            virDomainCheckpiontGetName
virDomainSnapshotGetParent          virDomainCheckpiontGetParent
virDomainSnapshotHasMetadata        (deferred for later)
virDomainSnapshotIsCurrent          (no counterpart, see note above)

Operate on a domain object to list all children:
virDomainSnapshotNum                (no counterparts, these are the old
virDomainSnapshotListNames           racy interfaces)
virDomainSnapshotListAllSnapshots   virDomainListAllCheckpoints

Operate on a child object to list descendents:
virDomainSnapshotNumChildren        (no counterparts, these are the old
virDomainSnapshotListChildrenNames   racy interfaces)
virDomainSnapshotListAllChildren    virDomainCheckpointListAllChildren

Operate on a domain to locate a particular child:
virDomainSnapshotLookupByName       virDomainCheckpointLookupByName
virDomainSnapshotCurrent            (no counterpart, see note above)
virDomainHasCurrentSnapshot         (no counterpart, old racy interface)

Operate on a snapshot to roll back to earlier state:
virDomainSnapshotRevert             (no counterpart, instead checkpoints
                                     are used in incremental backups via
				     XML to virDomainBackupBegin)

5a148ce846 remote: delete the avahi mDNS support
Libvirtd has long had integration with avahi for advertising libvirtd
using mDNS when TCP/TLS listening is enabled. For a long time the
virt-manager application had support for auto-detecting libvirtds

    connect: Drop avahi support

    Libvirtd can advertise itself over avahi. The feature is disabled by
    default though and in practice I hear of no one actually using it
    and frankly I don't think it's all that useful

    The 'Open Connection' wizard has a disproportionate amount of code
    devoted to this feature, but I don't think it's useful or worth
    maintaining, so let's drop it

I've never heard of any other applications having support for using
mDNS to detect libvirtd instances. Though it is theoretically possible
something exists out there, it is clearly going to be a niche use case
in the virt ecosystem as a whole.

By removing avahi integration we can cut down the dependency chain for
the basic libvirtd install and reduce our code maint burden.
