They recently were extracted to a separate function. They don't belong
together though. Since -numa formatting is pretty compact, move it to
the main function and rename qemuBuildNumaCommandLine to
qemuBuildMemoryDeviceCommandLine.

When starting up a VM libvirtd asks numad to place the VM in case of
automatic nodeset. The nodeset would not be passed to the memory device
formatter and the user would get an error.

This patch adds support for "vpindex", "runtime", "synic",
"stimer", and "vendor_id" features available in qemu 2.5+.

- When Hyper-V "vpindex" is on, guest can use MSR HV_X64_MSR_VP_INDEX
to get virtual processor ID.

- Hyper-V "runtime" enlightement feature allows to use MSR
HV_X64_MSR_VP_RUNTIME to get the time the virtual processor consumes
running guest code, as well as the time the hypervisor spends running
code on behalf of that guest.

- Hyper-V "synic" stands for Synthetic Interrupt Controller, which is
lapic extension controlled via MSRs.

- Hyper-V "stimer" switches on Hyper-V SynIC timers MSR's support.
Guest can setup and use fired by host events (SynIC interrupt and
appropriate timer expiration message) as guest clock events

- Hyper-V "reset" allows guest to reset VM.

- Hyper-V "vendor_id" exposes hypervisor vendor id to guest.

If a <graphics type='spice'> has no port nor tlsPort set, the generated
QEMU command line will contain -spice port=0.
This is later going to be ignored by spice-server, but it's better not
to add it at all in this situation.
As an empty -spice is not allowed, we still need to append port=0 if we
did not add any other argument.

Currently -spice addr=127.0.0.1 is generated, but spice-server is going
to ignore this as no port is specified.

The end goal is to avoid adding -spice port=0,addr=127.0.0.1 to QEMU command
line when no SPICE port is specified in libvirt XML.

Currently, the code relies on port=xx to always be present, so subsequent
args can be unconditionally appended with a leading ','. Since port=0
will no longer be added in a subsequent commit, we append a ',' to every
arg instead of prepending, and remove the last one before adding it to
the arg list.

Commit 'ef2ab8fd' moved just the virDomainConfNWFilterTeardown and left
the logic to save/restore the current error essentially doing nothing
in the error path for qemuBuildCommandLine.  So move it to where it
was meant to be.

Although the original code would reset the filter on command creation
errors after building the network command portion and commit 'ef2ab8fd'
altered that logic, the teardown is called during qemuProcessStop from
virDomainConfVMNWFilterTeardown and that code has the save/restore
last error logic, so just allow that code to handle the teardown rather
than running it twice. The qemuProcessStop would be called in the failure
path of qemuBuildCommandLine.

This function can be called over a domain definition that has no
video configured. The
tests/qemuxml2argvdata/qemuxml2argv-minimal.xml file could serve

segmentation fault in case there's none video configured.
