d20ebdda28 qemu: Switch to -accel
We currently use -machine accel=XXX which is just a syntax sugar
for -accel XXX. The former doesn't allow specifying arguments for
accelerator, because all arguments passed to -machine are
treated as arguments of machine itself.

The -accel argument was introduced in QEMU commit
v2.9.0-rc0~70^2~19 and since our minimum required version is
newer (2.11.0) we can safely assume its existence and use it
without any capability.

7bf6292fb3 qemu: always translate underscores to hyphens in CPU features
QEMU switched from using underscores in x86 CPU features to hyphens
in the 2.8.0 series with two commits

    target-i386: Remove underscores from feat_names arrays

  commit 54b8dc7c19cd781e96f1e9b001ca6001d804eb19
  Author: Eduardo Habkost <ehabkost@redhat.com>

    target-i386: Register aliases for feature names with underscores

Libvirt names use underscores so we conditionally tranlate the
names when talking to new QEMU. Since the min QEMU was raised to
version 2.11.0, all QEMU versions we talk to expect hypens, so
the translation can be done unconditionally.

d8f04f1575 qemuBuildControllerPCIDevStr: Format via JSON properties
Internally format the PCI controller properties into JSON, but convert
it back to a string so that we for now change just the SCSI controller.

The change in tests is expected as the 'port' field for various PCI
controllers is expected to be a number and thus can't be represented as
a hexadecimal value in JSON.

QEMU expects the following types:

'pci-bridge'
  chassis_nr=<uint8>     -  (default: 0)

'pxb-pcie':
  bus_nr=<uint8>         -  (default: 0)

'pcie-root-port'
  port=<uint8>           -  (default: 0)
  chassis=<uint8>        -  (default: 0)
  hotplug=<bool>         -  (default: true)

edf0b8211d qemuxml2argvtest: Add 'cpu-host-model' cases for all x86-64 real qemu caps versions
The host model expansion depends on the capability data, so in this case
it makes sense to have specific invocations of the test for all qemu
versions we have.
