45a61cbf68 util: xml: Fix confusing semantics of VIR_XML_PROP_OPTIONAL flag
The new enum helpers use a set of flags to modify their behaviour, but
the declared set of flags is semantically confusing:

 typedef enum {
     VIR_XML_PROP_OPTIONAL = 0, /* Attribute may be absent */
     VIR_XML_PROP_REQUIRED = 1 << 0, /* Attribute may not be absent */

Since VIR_XML_PROP_OPTIONAL is declared as 0 any other flag shadows it
and makes it impossible to detect. The functions are not able to detect
a semantic nonsense of VIR_XML_PROP_OPTIONAL | VIR_XML_PROP_REQUIRED and
it's a perfectly valid statement for the compilers.

In general having two flags to do the same boolean don't make sense and
the implementation doesn't fix any shortcomings either.

To prevent mistakes, rename VIR_XML_PROP_OPTIONAL to VIR_XML_PROP_NONE,
so that there's always an enum value used with the calls but it doesn't
imply that the flag makes the property optional when the actual value is
0.

Note that in case of def->blockio.logical_block_size,
def->blockio.physical_block_size and def->rotation_rate the wraparound
behaviour of 'virStrToLong_ui' was _not_ forward ported to the new code
as it makes no sense with the attributes.

c8238579fb lib: Drop internal virXXXPtr typedefs
Historically, we declared pointer type to our types:

  typedef struct _virXXX virXXX;
  typedef virXXX *virXXXPtr;

But usefulness of such declaration is questionable, at best.
Unfortunately, we can't drop every such declaration - we have to
carry some over, because they are part of public API (e.g.
virDomainPtr). But for internal types - we can do drop them and
use what every other C project uses 'virXXX *'.

This change was generated by a very ugly shell script that
generated sed script which was then called over each file in the
repository. For the shell script refer to the cover letter:

just be simplified to:

empty, thanks to passing it as a parameter and return an integer
to indicate error state - previously it returned pointer (or NULL
for both error and incomplete XML).
I also added a test case to test this functionality in the
qemuxml2xmltest.

The code went through some refactoring:
* change of a condition
* addition of a parameter
* change of order, that allowed removal of VIR_FREE
* removal of redundant labels and variables

657999b04f conf: add helper to test for sound device codec support
The check for ICH6 || ICH9 is repeated in many places in the code. The
new virDomainSoundModelSupportsCodecs() method provides a helper to
standardize this check.

fe304b02f0 conf: don't force existance of audio child elements
The attributes on the elements are optional, so we should not force the
elements themselves to be present, especially since we omit them when
formating the XML thus breaking round-tripping.

f84f04350b conf: add support for VNC power control setting
The <graphics type="vnc" .... powerControl="yes"/> option instructs the
VNC server to enable an extension that lets the client perform a
graceful shutdown, reboot and hard reset.

This is enabled by default since it cannot be assumed that the VNC
client user has administrator rights over the guest OS. In the case
where the VNC user is a guest administrator though, it is reasonable
to allow direct power control host side too.

bcdb634e1b domain_conf: Fix check for hyperv stimer
VIR_DOMAIN_HYPERV_STIMER happens to have the same numerical value as
VIR_DOMAIN_FEATURE_HYPERV, resulting in the if-block to always being
executed when a "<hyperv>" tag is found, whether or not it actually
contained a "<stimer>" tag. This had no ill effects, as virXPathNodeSet()
would simply return 0 if that tag does not exist.

1d9d9961ad vircgroup: enforce range limit for cpu.shares
Before the conversion to using systemd DBus API to set the cpu.shares
there was some magic conversion done by kernel which was documented in
virsh manpage as well. Now systemd errors out if the value is out of
range.

Since we enforce the range for other cpu cgroup attributes 'quota' and
'period' it makes sense to do the same for 'shares' as well.
