6604a3dd9f xenconfig: support xl<->xml conversion of rbd disk devices
The target= setting in xl disk configuration can be used to encode
meta info that is meaningful to a backend. Leverage this fact to
support qdisk network disk types such as rbd. E.g. <disk> config
such as

   <disk type='network' device='disk'>
     <driver name='qemu' type='raw'/>
     <source protocol='rbd' name='pool/image'>
       <host name='mon1.example.org' port='6321'/>
       <host name='mon2.example.org' port='6322'/>
       <host name='mon3.example.org' port='6322'/>
     </source>
     <target dev='hdb' bus='ide'/>
     <address type='drive' controller='0' bus='0' target='0' unit='1'/>
   </disk>

can be converted to the following xl config (and vice versa)

  disk = [ "format=raw,vdev=hdb,access=rw,backendtype=qdisk,
            target=rbd:pool/image:auth_supported=none:mon_host=mon1.example.org\\:6321\\;mon2.example.org\\:6322\\;mon3.example.org\\:6322"
         ]

Note that in xl disk config, a literal backslash in target= must
be escaped with a backslash. Conversion of <auth> config is not
handled in this patch, but can be done in a follow-up patch.

Also add a test for the conversions.

a44f1f85f9 xenconfig: produce key=value disk config syntax in xl formatter
The most formal form of xl disk configuration uses key=value
syntax to define each configuration item, e.g.

format=raw, vdev=xvda, access=rw, backendtype=phy, target=disksrc

Change the xl disk formatter to produce this syntax, which allows
target= to contain meta info needed to setup a network-based
disksrc (e.g. rbd, nbd, iscsi). For details on xl disk config
format, see  $xen-src/docs/misc/xl-disk-configuration.txt

Update the disk config in the tests to use the formal syntax.
But add tests to ensure disks specified with the positional
parameter syntax are correctly converted to <disk> XML.

e6ad2b69ae qemu: parse: drop redundant AddImplicitControllers
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

4066c73428 domain: add implicit controllers from post parse
Seems like the natural fit, since we are already adding other XML bits
in the PostParse routine.

Previously AddImplicitControllers was only called at the end of XML
parsing, meaning code that builds a DomainDef by hand had to manually
call it. Now those PostParse callers get it for free.

There's some test churn here; xen xm and sexpr test suite bits weren't
calling this before, but now they are, so you'll see new IDE controllers.
I don't think this will cause problems in practice, since the code already
needs to handle these implicit controllers like in the case when a user
defines their own XML.

73ed1d7401 tests: qemuargv2xml: hardcode disk auth usage
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

353de572a6 util: Refactor virHashForEach so it returns as soon as an iterator fails
The method will now return 0 on success and -1 on error, rather than number of
items which it iterated over before it returned back to the caller. Since the
only place where we actually check the number of elements iterated is in
virhashtest, return value of 0 and -1 can be a pretty accurate hint that it
iterated over all the items. However, if we really want to know the number of
items iterated over (like virhashtest does), a counter has to be provided
through opaque data to each iterator call. This patch adjusts return value of
virHashForEach, refactors the body, so it returns as soon as one of the
iterators fail and adjusts virhashtest to reflect these changes.

cc48d3a122 util: Add a return value to void hash iterators
Our existing virHashForEach method iterates through all items disregarding the
fact, that some of the iterators might have actually failed. Errors are usually
dispatched through an error element in opaque data which then causes the
original caller of virHashForEach to return -1. In that case, virHashForEach
could return as soon as one of the iterators fail. This patch changes the
iterator return type and adjusts all of its instances accordingly, so the
actual refactor of virHashForEach method can be dealt with later.

26946f674e virportallocatortest: Run on linux only
After the rework of mocking of our tests there's the
virportallocator test failing to link on mingw. Well, it's the
mocking library actually:

../gnulib/lib/.libs/libgnu.a(bind.o): In function `rpl_bind':
/home/jenkins/libvirt-mingw/build32/gnulib/lib/../../../gnulib/lib/bind.c:33: multiple definition of `rpl_bind'
.libs/virportallocatormock_la-virportallocatormock.o:/home/jenkins/libvirt-mingw/build32/tests/../../tests/virportallocatormock.c:79: first defined here

I've no idea why this matters to mingw and does not to others.
Nevertheless, if we make the test linux only the problem goes
away.

Apparently, our test for RTLD_NEXT is not sufficient because
mingw32 defines it. Lets put aside for a while fact that it has
the same value as RTLD_DEFAULT which by description has different
meaning, shall we?

d093d623e3 tests: qemuxml2xml: Always use different output file
Most qemuxml2xml tests expect that the input XML is unchanged after
parsing. This is unlike 99% of new qemu configs in the wild, which after
initial parsing end up with stable PCI device addresses. The xml2xml bit
doesn't currently hit that code path though, so most XML testing indeed
does not change.

Future patches will add that PCI address bits, which means most test cases
will have different output. So let's do away with the hardcoded same vs
different test split, and always track a separate output file. Tests can
still have same input and output, it just necessitates 2 separate XML files.

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

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.

c3bd0019c0 systemd: Modernize machine naming
So, systemd-machined has this philosophy that machine names are like
hostnames and hence should follow the same rules.  But we always allowed
international characters in domain names.  Thus we need to modify the
machine name we are passing to systemd.

In order to change some machine names that we will be passing to systemd,
we also need to call TerminateMachine at the end of a lifetime of a
domain.  Even for domains that were started with older libvirt.  That
can be achieved thanks to virSystemdGetMachineNameByPID().  And because
we can change machine names, we can get rid of the inconsistent and
pointless escaping of domain names when creating machine names.

So this patch modifies the naming in the following way.  It creates the
name as <drivername>-<id>-<name> where invalid hostname characters are
stripped out of the name and if the resulting name is longer, it
truncates it to 64 characters.  That way we can start domains we
couldn't start before.  Well, at least on systemd.

To make it work all together, the machineName (which is needed only with
systemd) is saved in domain's private data.  That way the generation is
moved to the driver and we don't need to pass various unnecessary
arguments to cgroup functions.

The only thing this complicates a bit is the scope generation when
validating a cgroup where we must check both old and new naming, so a
slight modification was needed there.
