qemu: Don't generate '-machine memory-backend' and '-numa memdev'

In 88957116c9 I've switched to -machine memory-backend=ID and
-object memory-backend-* because QEMU is obsoleting -mem-path
and -mem-prealloc. However, what I did not foresee was that using
-machine memory-backend in combination with -numa is not allowed
in QEMU. This was reported upstream and fortunately not released
yet.

The problem is that if domain has NUMA nodes then we will
generate memory-backend-* objects for NUMA nodes (because if QEMU
is new enough to expose default RAM ID it also supports -numa
memdev=) and adding non-NUMA memory backend is wrong.

cpu: Modify virCPUarmCompare to perform compare actions

Modify virCPUarmCompare in cpu_arm.c to perform compare action.
This patch only adds host to host CPU compare, the rest cases
remains the same. This is useful for source and destination host
compare during migrations to avoid migration between different
CPU models that have different CPU freatures.

Change the interface of esxUtil_ResolveHostname() to return a newly
allocated string with the result address, instead of forcing the callers
to provide a buffer and its size. This way we can simply (auto)free the
string, and make the function stacks smaller.

qemu: Taint cpu host-passthrough only after migration

From a discussion last year[1], Dan recommended libvirt drop the tain
flag for cpu host-passthrough, unless the VM has been migrated.

This repurposes the existing host-cpu taint flag to do just that.
