5846179a2e docs: Update the AMD SEV's spec URL
Luckily, the new URL still points to the same location, the only change
is in the document name where an escaped space (%20) was replaced by an
underscore.

5dca09c170 conf: Expose SEV feature in domain capabilities
Extend hypervisor capabilities to include sev feature. When available,
hypervisor supports launching an encrypted VM on AMD platform. The
sev feature tag provides additional details like Platform Diffie-Hellman
(PDH) key and certificate chain which can be used by the guest owner to
establish a cryptographic session with the SEV firmware to negotiate
keys used for attestation or to provide secret during launch.

b1c81567c7 docs: switch to using HTML5 doctype declaration
The HTML5 doctype is simply

  <!DOCTYPE html>

no DTD is present because HTML5 is no longer defined as an
extension of SGML.

XSL has no way to natively output a doctype without a public
or system identifier, so we have to use an <xsl:text> hack
instead.

df769041c2 domain_capabilities: Don't report machine type for bhyve
For some drivers the domain's machine type makes no sense. They
just don't use it. A great example is bhyve driver. Therefore it
makes very less sense to report machine in domain capabilities
XML.

14319c81a0 Show host model in domain capabilities
The domain capabilities XML is capable of showing whether each guest CPU
mode is supported or not with a possibility to provide additional
details. This patch enhances host-model capability to advertise the
exact CPU model which will be used as a host-model:

    <cpu>
        ...
        <mode name='host-model' supported='yes'>
            <model fallback='allow'>Broadwell</model>
            <vendor>Intel</vendor>
            <feature policy='disable' name='aes'/>
            <feature policy='require' name='vmx'/>
        </mode>
        ...

d4c007e6d5 domcaps: Add CPU usable flag
In case a hypervisor is able to tell us a list of supported CPU models
and whether each CPU models can be used on the current host, we can
propagate this to domain capabilities. This is a better alternative
to calling virConnectCompareCPU for each supported CPU model.

167280e7f6 domcaps: Add support for listing supported CPU models
The patch adds <cpu> element to domain capabilities XML:

    <cpu>
        <mode name='host-passthrough' supported='yes'/>
        <mode name='host-model' supported='yes'/>
        <mode name='custom' supported='yes'>
            <model>Broadwell</model>
            <model>Broadwell-noTSX</model>
            ...
        </mode>
    </cpu>

Applications can use it to inspect what CPU configuration modes are
supported for a specific combination of domain type, emulator binary,
guest architecture and machine type.

f05b6a918e domaincaps: Expose UEFI binary path, if it exists
Check to see if the UEFI binary mentioned in qemu.conf actually
exists, and if so expose it in domcapabilities like

  <value>/path/to/ovmf</value>

We introduce some generic domcaps infrastructure for handling
a dynamic list of string values, it may be of use for future bits.

614581f32b Introduce domain_capabilities
This new module holds and formats capabilities for emulator. If you
are about to create a new domain, you may want to know what is the
host or hypervisor capable of. To make sure we don't regress on the
XML, the formatting is not something left for each driver to
implement, rather there's general format function.

The domain capabilities is a lockable object (even though the locking
is not necessary yet) which uses reference counter.
