Existing qemuParseCommandLineMem() will parse "-m 4G" format string.
This patch allows it to parse "-m size=8126464k,slots=32,maxmem=33554432k"
format along with existing format. And adds a testcase to validate the changes.

Parse the -M (or -machine) command line option before starting
processing in earnest and have a fallback ready in case it's not
present, so that while parsing other options we can rely on
def->os.machine being initialized.

If the "/#" is missing from the provided iSCSI path, then we need
to provide the default LUN of /0; otherwise, QEMU will fail to parse
the URL causing a failure to either create the guest or hotplug
attach the storage.

During post parse, for any iSCSI disk or hostdev, scan the source
path looking for the presence of '/', if found, then we can assume
the LUN is provided.  If not found, alter the input XML to add the
"/0".  This will cause the generated XML to have the generated
value when the domain config is saved after post parse.

pSeries guests will soon need the new information; luckily,
we can figure it out automatically most of the time, so
users won't have to worry about it.

Our test data used a lot of different qemu binary paths and some
of them were based on downstream systems.

Note that there is one file where I had to add "accel=kvm" because
the qemuargv2xml code parses "/usr/bin/kvm" as virt type="kvm".

For every but the last argument, we also need space for a space
and a backslash.

Rewrap everything longer than 78 characters.

This is preferrable to -nographic which (in addition to disabling
graphics output) redirects the serial port to stdio and on OpenBIOS
enables the firmware's serial console.

VNC graphics already supports sockets but only via 'socket' attribute.
This patch coverts that attribute into listen type 'socket'.

For backward compatibility we need to handle listen type 'socket' and 'socket'
attribute properly to support old XMLs and new XMLs.  If both are provided they
have to match, if only one of them is provided we need to be able to parse that
configuration too.

To not break migration back to old libvirt if the socket is provided by user we
need to generate migratable XML without the listen element and use only 'socket'
attribute.

According to QEMU docs, the '-m' option for specifying RAM is by default
in MiB, and a suffix of "M" or "G" may be passed for values in MiB and
GiB respectively. This commit adds support and a test for the same.

We have stopped supporting Xenner some time ago.

All qemu versions we support have QEMU_CAPS_DEVICE, so checking
for it is redundant. Remove the usage.

The code diff isn't clear, but all that code is just inindented
with no other change.

Test cases that hit qemuDomainAssignAddresses but don't have
infrastructure for specifying qemuCaps values see lots of
churn, since now PCI addresses are in the XML output.

Upcoming patches are going to make the disk portion of these
test cases fail. In order to make it work, we would need to
extend the qemuargv2xml test infrastructure to handle qemuCaps.
This is worthwhile to do at some point but isn't critical.

Instead just drop the offending portion, which isn't even the
target of the test cases anyways

This wires up qemuDomainAssignAddresses into the new
virDomainDefAssignAddressesCallback, so it's always triggered
via virDomainDefPostParse. We are essentially doing this already
with open coded calls sprinkled about.

qemu argv parse output changes slightly since previously it wasn't
hitting qemuDomainAssignAddresses.

This patch adds by default a panic device with model s390 to S390 guests.

While working on the tests for the secret initialization vector, I found
that the existing iSCSI tests were lacking in how they defined the IQN.
Many had IQN's of just 'iqn.1992-01.com.example' for one disk while using
'iqn.1992-01.com.example/1' for the second disk (same for hostdevs - guess
how they were copied/generated).

Typically (and documented this way), IQN's would include be of the form
'iqn.1992-01.com.example:storage/1' indicating an IQN using "storage" for
naming authority specific string and "/1" for the iSCSI LUN.

So modify the input XML's to use the more proper format - this of course
has a ripple effect on the output XML and the args.

Also note that the "%3A" is generated by the virURIFormat/xmlSaveUri
to represent the colon.

Commit 119cd06e started setting the primary bool for the first
user-specified video even if user omitted the 'primary' attribute.

However this was done before the addition of the implicit device.
This broke startup of transient qemu domains with no <video>:
https://bugzilla.redhat.com/show_bug.cgi?id=1325757

Move this default to virDomainDefPostParseInternal,
after the addition of the implicit video device, to catch the implicit
video as well.

PostParse handles it for us now.

This causes some test suite churn; qemu's custom PostParse could is
now invoked before the generic AddImplicitControllers, so PCI
controllers end up sequentially in the XML before the generically
added IDE controllers. So it's just some XML reordering

The memory XML blanking is only there to avoid the unit= churn that
was added by default a long time ago.

Drop the blanking, switch over to using the standard comparison
helpers, and regenerate the output with VIR_TEST_REGENERATE_OUTPUT.

If a qemuargv has iscsi or ceph secrets on the command line, we will
convert that to XML like:

  <auth username='myname'>
    <secret type='iscsi'/>
  </auth>

This is not valid XML, as either a UUID or usage must be specified in
the secret block. It's not clear though how the argv2xml code can do
anything correct here, since XML like this requires a libvirt secret
object to have already been defined.

The current test suite handles this by blanking out any <secret> block
in the XML. This avoids domainschematest failures.

Instead of blanking, let's hardcode a usage= name. This lets us test
the other bits of generated <secret> XML, and is a step towards wiring
up VIR_TEST_REGENERATE_OUTPUT

Overwrite any randomly generated UUID to use a hardcoded value, so
we don't need to blank it when comparing XML.

Most of the qemuargv2xml tests are parsing old style qemu command
lines (with -disk, -serial, etc), and it gets its input from
qemuxml2argv output.

But since we've raise the minimum supported qemu version to 0.12.0,
which supports -device, once that changes propagates through libvirt
the vast majority of qemuxml2argv output is _not_ going to be using
old style qemu options.

In preparation for this, switch qemuargv2xml to use its own copies
of input and output, so it's not tied to qemuxml2argv results.

This is just a straight copy of the current tests.
