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:

6336fcd9f8 XML <source bridge='VMnet0'/> update in <interface type='bridge'/>
Previously, we accepted empty bridge name, because some old versions of
VMWare Workstation did not put it into the config. But this doesn't make
much sense - to have an interface type bridge with no name. We
circumvented this problem by generating an empty name but that is
equally wrong.

Therefore, fill in missing bridge names (according to the documentation
[1] the default bridge name is VMnet0) and error out if bridge name is
missing.

This partially reverts f246cdb5ac

08f8fd8413 conf: Add support for vDPA network devices
This patch adds new schema and adds support for parsing and formatting
domain configurations that include vdpa devices.

vDPA network devices allow high-performance networking in a virtual
machine by providing a wire-speed data path. These devices require a
vendor-specific host driver but the data path follows the virtio
specification.

When a device on the host is bound to an appropriate vendor-specific
driver, it will create a chardev on the host at e.g.  /dev/vhost-vdpa-0.
That chardev path can then be used to define a new interface with
type='vdpa'.

6d3cb071b4 vmx: fix logic handling mac address type

      <mac address='00:0c:29:dd:ee:fe' type='static'/>

    <interface type='bridge'>
      <mac address='aa:bb:cc:dd:ee:fd' type='generated'/>
      <source bridge='br2'/>
    </interface>

result in

 ethernet1.present = "true"
 ethernet1.networkName = "br1"
 ethernet1.connectionType = "bridged"
 ethernet1.addressType = "static"
 ethernet1.address = "00:0c:29:dd:ee:fe"
 ethernet1.checkMACAddress = "false"

 ethernet2.present = "true"
 ethernet2.networkName = "br2"
 ethernet2.connectionType = "bridged"
 ethernet2.addressType = "static"
 ethernet2.address = "aa:bb:cc:dd:ee:fd"
 ethernet2.checkMACAddress = "false"

which is flawed, as both type='static' and type='generated' in the XML
turn into 'static' in the VMX config.

The existence of the 'static' attribute is further overriding whether
the checkMACAddress config option is set as a side effect.

Both these pieces of flawed logic were introduced in

  commit 454e5961ab
  Author: Bastien Orivel <bastien.orivel@diateam.net>
  Date:   Mon Jul 13 16:28:53 2020 +0200

    Add a type attribute on the mac address element

which intentionally added the 'checkMACAddress' side effect based on
the 'type' attribute.

With this change, we're reverting the handling of checkMACAddress
to match what existed historically. The 'type' attribute now directly
maps to the addressType attribute, so the above config becomes:

 ethernet1.present = "true"
 ethernet1.networkName = "br1"
 ethernet1.connectionType = "bridged"
 ethernet1.addressType = "static"
 ethernet1.address = "00:0c:29:dd:ee:fe"

 ethernet2.present = "true"
 ethernet2.networkName = "br2"
 ethernet2.connectionType = "bridged"
 ethernet2.addressType = "generated"
 ethernet2.generatedAddress = "aa:bb:cc:dd:ee:fd"
 ethernet2.generatedAddressOffset = "0"

b7a92bce07 conf, vmx: check for OOM after calling xmlBufferCreate()
Although libvirt itself uses g_malloc0() and friends, which exit when
there isn't enouogh memory, libxml2 uses standard malloc(), which just
returns NULL on OOM - this means we must check for NULL on return from
any libxml2 functions that allocate memory.

xmlBufferCreate(), for example, might return NULL, and we don't always
check for it. This patch adds checks where it isn't already done.

(NB: Although libxml2 has a provision for changing behavior on OOM (by
calling xmlMemSetup() to change what functions are used to
allocating/freeing memory), we can't use that, since parts of libvirt
code end up in libvirt.so, which is linked and called directly by
applications that may themselves use libxml2 (and may have already set
their own alternate malloc()), e.g. drivers like esx which live totally
in the library rather than a separate process.)
