Commit 901d2b9c introduced virCgroupGetMemoryStat and replaced
the LXC virLXCCgroupGetMemStat logic in commit e634c7cd0. However,
in doing so the replacement wasn't exact as the LXC logic used
getline() to process the cgroup controller data, while the new
virCgroupGetMemoryStat used "memory.stat" manual buffer read/
processing which neglected to forward through @line in order
to read each line in the output.
To fix that, we should be sure to carry forward the @line value
for each line read updating it beyond that current @newLine value
once we've calculated the values that we want.

If polkit authentication is enabled, an attempt to open
the connection failed during virAccessDriverPolkitGetCaller
when the call to virIdentityGetCurrent returned NULL resulting
in the errors:
virAccessDriverPolkitGetCaller:87 : access denied:
Policy kit denied action org.libvirt.api.connect.getattr from <anonymous>
Because qemuProcessReconnect runs in a thread during
daemonRunStateInit processing it doesn't have the thread
local identity. Thus when the virGetConnectNWFilter is
called as part of the qemuProcessFiltersInstantiate when
virDomainConfNWFilterInstantiate is run the attempt to get
the idenity fails and results in the anonymous error above.
To fix this, let's grab/use the virIdenityPtr of the process
that will be creating the thread, e.g. what daemonRunStateInit
has set and use that for our thread. That way any other similar
processing that uses/requires an identity for any other call
that would have previously been successfully run won't fail in
a similar manner.

Changes made to manage and utilize a secondary connection
driver to APIs outside the scope of the primary connection
driver have resulted in some confusion processing polkit rules
since the simple "access denied" error message doesn't provide
enough of a clue when combined with the "authentication failed:
access denied by policy" as to which connection driver refused
or failed the ACL check.
In order to provide some context, let's modify the existing
"access denied" error returned from the various vir*EnsureACL
API's to provide the connection driver name that is causing
the failure. This should provide the context for writing the
polkit rules that would allow access via the driver, but yet
still adhere to the virAccessManagerSanitizeError commentary
regarding not telling the user why access was denied.

When no server name is provided in the URI, modern versions of libxml2
will set the port to '-1'. This is a change from behaviour with earlier
versions which set it to 0.
Libvirt expects the port to be 0 in these cases and as a result we get a
bug when connecting to URIs which lack a server name:
$ virsh -c test+ssh:///default list
error: failed to connect to the hypervisor
error: Cannot recv data: Bad port '-1': Connection reset by peer
This libxml2 change was attempting to fix another bug identified by
libvirt where it didn't roundtrip URIs correctly in:
beb7281055
Essentially libxml2 was not expecting apps to look at the URI port
field when the server name is not provided. This was a reasonable
assumption, but none the less libvirt did look at it :-)
The fix is to ensure we explicitly set port to 0 when server name
is not present, avoiding undefined behaviour for the port field in
libxml2.

VFIO AP has a limitation on a single device per domain, however, when

There's a lot of stuff going on in src/conf/nodedev_conf which is
sometimes not directly related to config and we're not really consistent
with putting only parser/formatter related stuff here, e.g. like we do
for domains. So, let's start simply by adding a new module
node_device_util containing some of the helpers. Unfortunately, even
though these helpers tend to open a secondary driver connection and would
be much therefore better suited as a nodedev driver module, we can't do
that without pulling headers from the driver into conf/ and that's wrong
because we want conf/ to stay driver-agnostic.

Since commit v4.7.0-302-ge6d77a75c4 processing RESUME event is mandatory
for updating domain state. But the event handler explicitly ignored this
event in some cases. Thus the state would be wrong after a fake reboot
or when a domain was rebooted after it crashed.
BTW, the code to ignore RESUME event after SHUTDOWN didn't make sense
even before making RESUME event mandatory. Most likely it was there as a
result of careless copy&paste from qemuProcessHandleStop.
The corresponding debug message was clarified since the original state
does not have to be "paused" only and while we have a "resumed" event,
the state is called "running".

The current qemuProcessReconnect logic paints a broad brush
determining that the shutdown reason must be crashed if it was
determined that the domain was started with -no-shutdown; however,
there's many other ways to get to the error label, so let's narrow
our reasoning window for using VIR_DOMAIN_SHUTOFF_CRASHED to the
period where we essentially know we've tried to create to the
monitor and before we were successful in opening the connection.
Failures that occur outside that window would thus be considered
as VIR_DOMAIN_SHUTOFF_UNKNOWN, at least for now.

reconnection failure used VIR_DOMAIN_SHUTOFF_FAILED; however, that

When QEMU_CAPS_NO_SHUTDOWN checking was removed in commit fe35b1ad6
the conditional state was just left at VIR_DOMAIN_SHUTOFF_CRASHED.
So introduce qemuDomainIsUsingNoShutdown which will manage the
condition when the domain was started with -no-shutdown so that
when/if reconnection failure occurs we can restore the decision
point used to determine whether CRASHED or UNKNOWN is provided.
