Allow the driver level cgroup to be managed explicitly by the

reporting of failures. Also allow for creation of cgroups for
unprivileged drivers if controller is accessible by the user.

GCC >= 4.4 assumes the 'printf' attribute refers to the native
runtime libraries format specifiers. Thanks to gnulib, libvirt
has GNU format specifiers everywhere.  This means we need to
use 'gnu_printf' with GCC >= 4.4 to get correct compiler
checking of printf format specifiers.

If the qemu binary supports "-no-kvm" and/or "-no-kqemu", they should
always be added for plain "qemu" domains.  Previously, we omitted them
whenever the host and guest architectures implied that they would be
disabled automatically, but that logic was flawed in some cases
(such as i686 and x86_64).

qemu network devices are hot-unplugged in two stages - first the PCI NIC
is removed using 'pci_del <pci_addr>' and then the backend is removed
using 'host_net_remove <vlan> <name>'.

In order to perform these operations we need to have retained the
PCI address, backend name and vlan number.

* src/qemu_driver.c: add qemudDomainDetachNetDevice()

When we pci_add a NIC, we need to retain the PCI address assigned by
qemu for using during detach.

* src/qemu_driver.c: use qemudParsePciAddReply() to pull the PCI
  address from the pci_add reply

* src/domain_conf.c: handle storing and parsing the PCI address in the
  domain state XML file

The current code for parsing pci_add replies ignores the the domain and
bus numbers. Re-write the code to rectify that.

Also, since pci_add is used for NIC hotplug as well ask disk hotplug,
re-factor the code into a separate function.

* src/qemu_driver.c: add qemudParsePciAddReply() function which can
  handle parsing domain and bus numbers

If we fail to pci_add a NIC, we should remove the network backend and
leave things the way we found them. To do that, we pre-allocate a
host_net_remove monitor command and issue that if the pci_add fails.
If the remove fails, we just log a warning.

We can only do this if we have a name for the network backend and
we know the vlan number its associated with.

* src/qemu_driver.c: host_net_remove the network backend if the
  pci_add fails

Implement basic NIC hotplug support using the 'host_net_add' and
'pci_add' qemu monitor commands.

For now, we don't support 'bridge' or 'network' types.

Also, if pci_add fails, we currently fail to remove the backend
which we added.

Finally, NIC hot-unplug support is missing.

* src/qemu_driver.c: add qemudDomainAttachNetDevice()

* src/qemu_conf.[ch]: export qemuBuildNicStr(), qemuBuildHostNetStr()
  and qemuAssignNames()

* src/libvirt_private.syms: export virDomainNetTypeToString()

qemudDomainChangeEjectableMedia() currently extracts the qemu command
line flags, but other device attaching code might need it, so move
the qemudExtractVersionInfo() call up a frame.

* src/qemu_driver.c: move the qemudExtractVersionInfo() call from
  qemudDomainChangeEjectableMedia() to qemudDomainAttachDevice()

Currently, an interface's vlan number corresponds to its index in
the table of network interfaces. That is no longer true when we
allow devices to be removed.

To fix this, we store the vlan number in the domain's state XML
so that it survives libvirtd restarts.

* src/domain_conf.h: add vlan number to virDomainNetDef

* src/domain_conf.c: store it in XML as <state vlan='N'/>, defaulting
  to -1 if this is state saved by a previous version of libvirt

* src/qemu_conf.c: assign vlan numbers before starting qemu

The qemu driver needs to assign and keep track of identifiers for
network devices so that it can remove them. We need to keep this state
across libvirtd restarts, but it's not configuration that needs to
be kept across guest restarts.

* src/domain_conf.c: parse and format <state nic="foo" hostnet="bar"/>

We need these so that we can remove the devices via the monitor.

* src/domain_conf.h: add nic_name and hostnet_name to virDomainNetDef

* src/domain_conf.c: free nic_name and hostnet_name

* src/qemu_conf.c: add qemuAssignNetNames(), use it if qemu has
  support for the param and pass the names on the command line

* tests/qemuxml2argv*: add a test for this

Add QEMUD_CMD_FLAG_NET_NAME to indicate that '-net ...,name=foo' is
supported and QEMUD_CMD_FLAG_HOST_NET_ADD to indicate that the
'host_net_add' monitor command is available.

Set both these flags if the qemu version is greater than 0.10.0.
Checking via the '-help' output would not work for the monitor command
and even for the command line arg, it would be quite fragile.

* src/qemu_conf.h: add new flags as aliases of QEMUD_CMD_FLAG_0_10

* src/qemu_conf.c: set QEMUD_CMD_FLAG_0_10 for versions >= 0.10.0

* tests/qemuhelptest.c: set QEMUD_CMD_FLAG_0_10 for the appropriate
  qemu versions

Re-factor this code so that it can be used for NIC hotplug
too. The awkward prefix and type_sep arguments are needed to
allow us to do "host_net_add tap vlan=..."

* src/qemu_conf.c: factor the net backend string formatting
  code into its own function

Re-factor this code so that it can be used for NIC hotplug
too. The awkward arguments are needed to allow use to do
"pci_add auto nic macaddr=..."

* src/qemu_conf.c: factor the nic string formatting code into
  its own function

When we hot-plug a disk device into a qemu guest, we need to retain its
PCI address so that it can be removed again later. Currently, we do
retain the slot number, but not across libvirtd restarts.

Add <state devaddr="xxxx:xx:xx"/> to the disk device XML config when the
VIR_DOMAIN_XML_INTERNAL_STATUS flag is used. We still don't parse the
domain and bus number, but the format allows us to do that in future.

* src/domain_conf.h: replace slotnum with pci_addr struct, add helper
  for testing whether the address is valid

* src/domain_conf.c: handle formatting and parsing the address

* src/qemu_driver.c: store the parsed slot number as a full PCI address,
  and use this address with the pci_del monitor command

* src/vbox/vbox_tmpl.c: we're debug printing slotnum here even though
  it can never be set, just delete it

We need to store things like device names and PCI slot numbers in the
qemu domain state file so that we don't lose that information on
libvirtd restart. Add a flag to indicate that this information should
be parsed or formatted.

Make bit 16 and above of the flags bitmask for internal use only and
consume the first bit for this new status flag.

* include/libvirt/libvirt.h: add VIR_DOMAIN_XML_FLAGS_MASK

* src/libvirt.c: reject private flags in virDomainGetXMLDesc()

* src/domain_conf.h: add VIR_DOMAIN_XML_INTERNAL_STATUS

* src/domain_conf.c: pass the flag from virDomainObjParseXML() and
  virDomainSaveStatus

* src/virsh.c: rename interface into iface
