This patch is the result of running the following command in the docs
directory: sed -i 's/\t/        /g; s/\s*$//' *.html.in

* docs/*.html.in:convert tabs into 8 spaces and remove trailing whitespace

* src/qemu/qemu_conf.c: Update qemudBuildCommandLineChrDevStr to use a
  virBuffer

* src/qemu_qemu_conf.c: Cleanup usage of virBuffer in qemudBuildCommandLine

* src/internal.h (ATTRIBUTE_SENTINEL): New, it's a ggc feature and
  protected as such
* src/util/buf.c (virBufferStrcat): Use it.
* src/util/ebtables.c (ebtablesAddRemoveRule): Use it.
* src/util/iptables.c (iptableAddRemoveRule: Use it.
* src/util/qparams.h (new_qparam_set, append_qparams): Use it.
* docs/apibuild.py: avoid breaking the API generator with that new
  internal keyword macro

This matches the expected behavior of state drivers such as QEMU.

Performs changes needed when stopping a VM (which are currently duplicated
in several places, and forgotten in others).

* src/qemu/qemu_driver.c: in qemudDomainMigratePerform call
  doPeer2PeerMigrate for VIR_MIGRATE_PEER2PEER.

* src/util/network.c: Add htons and ntohs in virSocket(Get|Set)Port

* src/phyp/phyp_driver.[ch]: add new entry points and a number of
  cleanups

* include/libvirt/virterror.h src/util/virterror.c: add a new error
  VIR_ERR_CONFIG_UNSUPPORTED for valid but unsupported configuration options
* src/conf/domain_conf.c: Throw an error if guestfwd address isn't IPv4
  and cleanup a number of parsing return error values.

allows the following to be specified in a domain:
<channel type='pipe'>
  <source path='/tmp/guestfwd'/>
  <target type='guestfwd' address='10.0.2.1' port='4600'/>
</channel>

* proxy/Makefile.am: add network.c as dep of domain_conf.c
* docs/schemas/domain.rng src/conf/domain_conf.[ch]: extend the domain
  schemas and the parsing/serialization side for the new construct

QEmu support will add the following on the qemu command line:
 -chardev pipe,id=channel0,path=/tmp/guestfwd
 -net user,guestfwd=tcp:10.0.2.1:4600-chardev:channel0

* src/qemu/qemu_conf.c: Add argument output for channel
* tests/qemuxml2(argv|xml)test.c: Add test for <channel> domain syntax

* src/qemu/qemu_conf.h: defines a new QEMUD_CMD_FLAG_CHARDEV flag
* src/qemu/qemu_conf.c: parse the output for -chardev and set flag
  appropriately

A character device's target (it's interface in the guest) had only a
single property: port. This patch is in preparation for adding targets
which require other properties.
Since this changes the conf type for character devices this affects
a number of drivers:

* src/conf/domain_conf.[ch] src/esx/esx_vmx.c src/qemu/qemu_conf.c
  src/qemu/qemu_driver.c src/uml/uml_conf.c src/uml/uml_driver.c
  src/vbox/vbox_tmpl.c src/xen/xend_internal.c src/xen/xm_internal.c:
  target properties are moved into a union in virDomainChrDef, and a
  targetType field is added to identify which union member should be
  used. All current code which touches a virDomainChrDef is updated both
  to use the new union field, and to populate targetType if necessary.

Current implementation of lxc driver creates vethN named
interface(s) in the host and passes as it is to a container.
The reason why it doesn't use ethN is due to the limitation
that one namespace cannot have multiple iterfaces that have
an identical name so that we give up creating ethN named
interface in the host for the container.

However, we should be able to allow the container to have
ethN by changing the name after clone(CLONE_NEWNET).

* src/lxc/lxc_container.c src/lxc/veth.c src/lxc/veth.h: do the clone
  and then renames interfaces eth0 ... ethN to keep the interface names
  familiar in the domain

* src/lxc/lxc_driver.c: refactor lxcDomainSetAutostart() to avoid deep
  indentation of the code

* src/lxc/lxc_container.c src/lxc/lxc_controller.c src/lxc/lxc_driver.c
  src/lxc/veth.c: most of cleanups are just capitalizing their messages
  though, some fixes wrong error messages and awkward indentations, and
  improves error messages.

* src/lxc/lxc_container.c src/lxc/lxc_controller.c src/lxc/lxc_driver.c
  src/lxc/veth.c: fix broken function comments

* src/qemu/qemu.conf src/qemu/qemu_conf.c src/qemu/qemu_conf.h: there is
  a new config type option for mac filtering
* src/qemu/qemu_bridge_filter.[ch]: new module for the ebtable entry points
* src/qemu/qemu_driver.c: plug the MAC filtering at the right places
  in the domain life cycle
* src/Makefile.am po/POTFILES.in: add the new module

* configure.in: look for ebtables binary location if present
* src/Makefile.am: add the new module
* src/util/ebtables.[ch]: new module and internal APIs around
  the ebtables binary
* src/libvirt_private.syms: export the symbols only internally

This should be a no op for now, but we will use this function to set up
transient state in the future.

- Implement DomainGetMaxVCPUs
- Use GetMaxVCPUs to validate requested CPU amount
- Deny the 'hotplug' for a running domain.

Pretty sure this would deadlock now that we have proper locking, so
remove the code.

- Don't duplicate SystemError
- Use proper error code in domain_conf
- Fix a broken error call in qemu_conf
- Don't use VIR_ERR_ERROR in security driver (isn't a valid code in this case)

All drivers have copy + pasted inadequate error reporting which wraps
util.c:virGetHostname. Move all error reporting to this function, and improve
what we report.

Changes from v1:
  Drop the driver wrappers around virGetHostname. This means we still need
  to keep the new conn argument to virGetHostname, but I think it's worth
  it.

* src/conf/interface_conf.c: the code was erronously returning -1
  in the two functions if <dhcp> is not provided

* src/conf/interface_conf.c: lack of one of these in the live xml output
  was causing the parse in virInterfaceDefParseBond() to fail

* src/conf/interface_conf.c: forgot to free the structure itself

This patch updates the xml parsing and formatting, and the associated
virInterfaceDef data structure to support IPv6, along the way adding
support for multiple protocols per interface, and multiple IP
addresses per protocol.
* src/conf/interface_conf.[ch]: update the structures, code for parsing
  and serialization

This patch adds the flag VIR_INTERFACE_XML_INACTIVE to
virInterfaceGetXMLDesc's flags. When it is*not* set (the default), the
live interface info will be returned in the XML (in particular, the IP
address(es) and netmask(s) will be retrieved by querying the interface
directly, rather than  reporting what's in the config file). The
backend of this is in netcf's ncf_if_xml_state() function.

* configure.in libvirt.spec.in: requires netcf >= 0.1.3
* include/libvirt/libvirt.h.in: adds flag VIR_INTERFACE_XML_INACTIVE
* src/conf/interface_conf.c src/interface/netcf_driver.c src/libvirt.c:
  update the parsing and backend routines accordingly
* tools/virsh.c: change interface edit to inactive definition and
  adds the inactive flag for interface dump

The minimal XML returned from ncf_if_xml_state() doesn't contain this
attribute (which makes no sense in the case of reporting current
status of the interface), and it was preventing it from passing
through the parse/format step.

* src/conf/interface_conf.[ch]: add a new virInterfaceStartMode value
  and modify loading/saving accordingly

The virStateInitialize() call for starting up stateful drivers
may require that the event loop is running already. This it is
neccessary to start the event loop before this call. At the
same time, network clients must not be processed until afte
virStateInitialize has completed.

The qemudListenUnix() and remoteListenTCP() methods must
therefore not register file handle watches, merely open the
network sockets & listen() on them. This means clients can
connected and are queued, pending completion of initialization

The qemudRunLoop() method is moved into a background thread
that is started early to allow access to the event loop during
driver initialization. The main process thread leader pretty
much does nothing once the daemon is running, merely waits
for the event loop thread to quit

* daemon/libvirtd.c, daemon/libvirtd.h: Move event loop into
  a background thread
* daemon/THREADING.txt: Rewrite docs to better reflect reality

suggested by danpb on irc, patch by danken fixed for proper C syntax

* python/libvirt-override.c: on event callback release the python
  interpreter lock and take it again when coming back so that the
  callback can reinvoke libvirt.

There are places where an interface will not have a mac address, and netcf
returns this as a NULL pointer rather than a pointer to an empty string.
Rather than checking for this all over the place in libvirt, just save it
in the virInterface object as an empty string.

* src/datatypes.c: allow NULL mac in virGetInterface()
