Add vcpupin support to virt-install so that it can create guest
domains with statically allocated vcpu pinning towards a given cpuset.
Syntax: to pin vcpu=0 to cpuset="1,3" and vcpu=1 to cpuset=2
--cputune vcpupin0.vcpu=0,vcpupin0.cpuset=1,3,vcpupin1.vcpu=1,vcpupin1.cpuset=2
generates below XML description for the guest domain.
<cputune>
<vcpupin vcpu="0" cpuset="1,3"/>
<vcpupin vcpu="1" cpuset="2"/>
</cputune>

libvirt supports guest CPU cache by commit df13c0b, So add this feature
to virt-install to configure cpu L3 cache mode.
Currently, The valid values are 'passthrough', 'emulate' or 'disable'.
say:
--cpu host-passthrough,cache.mode=passthrough
or
--cpu $CPU,cache.mode=emulate,cache.level=3
or
--cpu $CPU,cache.mode=disable

There are multiple models of the panic device, the address type is only
one and is valid only for "isa" model.
To not break the virt-install/virt-xml the command line parser needs to
be updated. Before this patch there was only one parameter that
configured the "iobase". Now the first parameter configures a model
but to keep it backward compatible it follows these rules:
1. there is only one parameter and it matches known model:
--panic isa
<panic model='isa'>
<address iobase='0x505' type='isa'/>
</panic>
2. there is only one parameter and it doesn't match any model:
--panic 0x505
<panic model='isa'>
<address iobase='0x505' type='isa'/>
</panic>
3. there are two parameters:
--panic isa,iobase=0x505
<panic model='isa'>
<address iobase='0x505' type='isa'/>
</panic>

This element controls hot(un)plugable memory for the guest in
addition to the initial memory configured by <memory> element.
One has to configure <maxMemory> and guest numa nodes using <numa>
element to enable hot(un)plug of memory modules.

We forgot to mention --qemu-commandline in virt-xml.pod.
Also added an example copied from Cole's blog.

If this flag is specified, --import|--boot will create a transient
libvirt domain, ie. one which goes away when the guest shuts down or
the host is rebooted.
(crobinso: some tweaks and tests)
This is the new style socket support, where we request libvirt to
allocate a socket path for us. Plus this is the only way to enable
socket support for type=spice
This exposes every device <address> option, for each device
cli option. So --disk, --network, --video, etc.
Fill out a few more address XML bits as well
Add a special listen value to disable any extra display server listening
socket. This is necessary now that qemu prevents starting a spice+virgl
VM with listening sockets (until spice allows remoting with virgl).

Add a --graphics option to enable accelarated rendering using
OpenGl. This is used only by Spice (and for local only guests atm).

So we can call clear() on a Guest owned VirtualDisk, and it actually
does the correct thing. This allows us to enable clearxml= cli option
for most devices.
