If mode='passthrough', the virtual CPU will have the same number of address

Supported TPM versions are reported in domain capabilities. These

The qemuDomainDefCPUPostParse() does a bit more than filling in
missing info. It also validates CPU cache configuration. Move
that code into qemuValidateDomainDefCpu() where the code fits
better.
And since I need to fix indentation of existing code in
qemuValidateDomainDefCpu(), I'm taking this opportunity and move
error messages onto single line. Interestingly, this uncovers a
bug we have in sc_prohibit_diagnostic_without_format syntax-check
rule, because previously a virReportError() with a message
spawned over three lines was not caught but not it is. But
trying to understand that regex is a job for another time.

Add the ability to configure a qemu-vdagent in guest domains. This
device is similar to the spice vdagent channel except that qemu handles
the spice-vdagent protocol messages itself rather than routing them over
a spice protocol channel.
The qemu-vdagent device has two notable configuration options which
determine whether qemu will handle particular vdagent features:
'clipboard' and 'mouse'.
The 'clipboard' option allows qemu to synchronize its internal clipboard
manager with the guest clipboard, which enables client<->guest clipboard
synchronization for non-spice guests such as vnc.
The 'mouse' option allows absolute mouse positioning to be sent over the
vdagent channel rather than using a usb or virtio tablet device.
Sample configuration:
<channel type='qemu-vdagent'>
<target type='virtio' name='com.redhat.spice.0'/>
<source>
<clipboard copypaste='yes'/>
<mouse mode='client'/>
</source>
</channel>
