Internally we already collect x86 host family + model + stepping
numeric values. This exposed them in capabilities CPU output.
Example:
$ sudo virsh capabilities | grep -A1 -B1 signature
<microcode version='240'/>
<signature family='6' model='94' stepping='3'/>
<counter name='tsc' frequency='3408010000' scaling='no'/>
Users need to know these values to calculate an expected.

The check was historically done only for _TYPE_VOLUME disks, but
refactors to allow _TYPE_VOLUME disks in the backing chain caused a
regression where we'd reject startupPolicy also for _TYPE_BLOCK disks
which historically worked well.
Fix it by using the 'virDomainDiskDefValidateStartupPolicy' helper and
use it only when the top level image is a _TYPE_VOLUME as in other cases
it was already validated. This also allows _TYPE_BLOCK volumes to use
startup policy.

Our startup policy checkers work only for local paths, so disk sources
such as NVMe, or vhost-user can't be used with startup policy.
Unfortunately the validation did not catch these cases. Fix it.

This patch introduces the logic to format and parse remote NVRAM.
Update NVRAM element schema, and docs for supporting network backed
NVRAM. NVRAM backed over network would give the flexibility to start
the VM on any host without having to worry about where to get the latest
nvram image.
<nvram type='network'>
<source protocol='iscsi' name='iqn.2013-07.com.example:iscsi-nopool/0'>
<host name='example.com' port='6000'/>
</source>
</nvram>
or
<nvram type='file'>
<source file='/var/lib/libvirt/nvram/guest_VARS.fd'/>
</nvram>
In the qemu driver we will support the new definition only with qemu's
supporting -blockdev.

Since we now have a full virStorageSource for storing the nvram path we

For now we keep it functionally identical to the previous impl.
