Current support for bus master (clearing OK bit) together with the need to
support guests which do not enable PCI bus mastering, leads to extra state in
VIRTIO_PCI_FLAG_BUS_MASTER_BUG bit, which isn't robust in case of cross-version
migration for the case when guests use the device before setting DRIVER_OK.

Rip out this code, and replace it:
-   Modern QEMU doesn't need VIRTIO_PCI_FLAG_BUS_MASTER_BUG
    so just drop it for latest machine type.
-   For compat machine types, set PCI_COMMAND if DRIVER_OK
    is set.

As this is needed for 2.1 for both pc and ppc, move PC_COMPAT macros from pc.h
to a new common header.

We used to be able to address both the QEMU and the KVM APIC via "apic".
This doesn't work anymore. So we need to use their parent class to turn
off the vapic on machines that should not expose them.

Commit 261747f1 ("vl: Use MachineClass instead of global QEMUMachine
list") broke the ordering of the machine types in the user-visible output
of

  qemu-system-XXXX -M \?

This occurred because registration was rebased from a manually maintained
linked list to GLib hash tables:

  qemu_register_machine()
    type_register()
      type_register_internal()
        type_table_add()
          g_hash_table_insert()

and because the listing was rebased accordingly, from the traversal of the
list to the traversal of the hash table (rendered as an ad-hoc list):

  machine_parse()
    object_class_get_list(TYPE_MACHINE)
      object_class_foreach()
        g_hash_table_foreach()

The current order is a "random" one, for practical purposes, which is
annoying for users.

Introduce new members QEMUMachine.family and MachineClass.family, allowing
machine types to be "clustered". Introduce a comparator function that
establishes a total ordering between machine types, ordering machine types
in the same family next to each other. In machine_parse(), list the
supported machine types sorted with the comparator function.

The comparator function:
- sorts whole families before standalone machine types,
- sorts whole families between each other in alphabetically increasing
  order,
- sorts machine types inside the same family in alphabetically decreasing
  order,
- sorts standalone machine types between each other in alphabetically
  increasing order.

After this patch, all machine types are considered standalone, and
accordingly, the output is alphabetically ascending. This will be refined
in the following patches.

QEMU currently allows the number of VCPUs to not be a multiple of the
number of threads per socket, but the smbios socket count calculation
introduced by commit c97294ec doesn't
take that into account, triggering an assertion. e.g.:

  $ ./x86_64-softmmu/qemu-system-x86_64 -smp 4,sockets=2,cores=6,threads=1
  qemu-system-x86_64: /home/ehabkost/rh/proj/virt/qemu/hw/i386/smbios.c:825: smbios_get_tables: Assertion `smbios_smp_sockets >= 1' failed.
  Aborted (core dumped)

Socket count calculation doesn't belong to smbios.c and should
eventually be moved to the main SMP topology configuration code. But
while we don't move the code, at least make it correct by rounding up
the division.

This adds synchronisation of the 6 vcpu registers (only 32bits of
them) that vmport.c needs between Xen and QEMU.

This is to avoid a 2nd and 3rd exchange between QEMU and Xen to
fetch and put these 6 vcpu registers used by the code in vmport.c
and vmmouse.c

The registers are passed in the new shared page provided by
HVM_PARAM_VMPORT_REGS_PFN.

Add new array to XenIOState that allows selection of current_cpu by
vcpu id.

Now pass XenIOState to handle_ioreq().

Add new routines regs_to_cpu(), regs_from_cpu(), and
handle_vmport_ioreq().

The virtio-rng backend is currently linked twice, once in the proxy
device (e.g. virtio-rng-pci) and once in virtio-rng-device.  This causes
a double unref of the backend when the parent device is unplugged.

To fix this, make the proxy device use an alias, similar to what is
already being done for the iothread link.

bits_per_pixel that are less than 8 could result in accessing
non-initialized buffers later in the code due to the expectation
that bytes_per_pixel value that is used to initialize these buffers is
never zero.

streams support in usb-redir and usb-host works only with recent enough
versions of the support libraries (libusbredir and libusbx).  Failure
mode is rather unelegant:  Any stream usb transfers will throw stall
errors.  Turning off support for streams in the xhci host controller
will work better as the guest can figure beforehand that streams are
not going to work.

When a process in a guest uses an emulated smartcard, libcacard running
on the host passes the PIN from the guest to the PK11_Authenticate NSS
function. The first time PK11_Authenticate is called the passed in PIN
is used to unlock the certificate database. Subsequent calls to
PK11_Authenticate will transparently succeed, regardless of the passed in
PIN. This is a convenience for applications provided by NSS.

Of course, the guest may have many applications using the one emulated
smart card all driven from the same host QEMU process.  That means if a
user enters the right PIN in one program in the guest, and then enters the
wrong PIN in another program in the guest, the wrong PIN will still
successfully unlock the virtual smartcard.

This commit forces the NSS certificate database to be locked anytime an
applet is selected on an emulated smartcard by calling vcard_emul_logout.

vcard_emul_reset currently only logs NSS out, but there is a TODO
for potentially sending insertion/removal events when powering down
or powering up.

For clarity, this commit moves the current guts of vcard_emul_reset to
a new vcard_emul_logout function which will never send insertion/removal
events. The vcard_emul_reset function now just calls vcard_emul_logout,
but also retains its TODO for watching power state transitions and sending
insertion/removal events.

The local variable "type" in virtio_scsi_handle_ctl represents the tmf
command type from the guest and it has the same meaning as the
req->req.tmf.type. However, before the invoking of virtio_scsi_parse_req
the req->req.tmf.type doesn't has the correct value(just initialized to
zero). Therefore, we need to use the "type" variable to judge the case.
