This patch modifies the way how qemu_command is created. Instead
of long string it creates a representation of devices, which behaves
similarily to qemu's qdev.

Current implementation is very limited and only handles PCI bus. All
devices are created as simple StringDevices so the benefit might
not be obvious. But later patches adds specific devices (usb, image,
...) and their specific behaviour.

Additionally this patch adds the basic support for q35 machine.

Later the support for automatic check of running VM and representation
will be added.

NOTE: This version's pci addresses are not assigned properly as
      upstream currently uses different method. Following patch
      removes the original mechanism and uses the one from this patch.

virttest.test_setup: Add some hugepage related config params

Pygithub update

When an exception is thrown upon reading from cache,
attempt to remove the related entries being operated on.
An exception will still be thrown, however the cache
will not be corrupted with bad entries.

Also, ran into RH BZ 954156 when running cache_populate.py
as it loads commit authors for issue #362:

bsddb.db.DBPageNotFoundError: (-30986, 'DB_PAGE_NOTFOUND: Requested page
not found')

Accessing any vm_xml.devices member requiring an undefined
device xml module resulted in an extremely unhelpful error:

AttributeError: "type object 'exceptions.NotImplementedError' has no
attribute 'new_from_element'"

This commit adds a stub-class generating metaclass for undefined
devices.  The generated stub-class provides the minimal required
interface for the higher-level vm_xml.VMXMLDevices class.  Each
stub class will raise one-warning upon first use.  This is to notify
and make clear to all uses of these devices, that the interface
will likely change in the future.

Added unittests to verify functionality of stub-class metaclass.  Also
added plenty of docstrings and docstring updates.

* added del_seclabel accessor method so we have a complete set.

* get_seclabel() accessor method should raise exception
  for non-existant value instead of returning None value.

* set_seclabel() accessor method should not set unspecified
  imput attribute values.

* set_seclabel() should not perform non-data manipulation actions
  (self.define/undefine) since can introduce hidden side-effects.

* Made libvirt_xml_unittests fail tests for any subject-call
  which uses undefined dummy_virsh commands.

* Extended seclabel unittests for multi-mode access and
  exception checking.
