The API can be used to query current state of an interface to VMM used
to control a domain. In QEMU world this translates into monitor
connection.

virStreamRecv is for reading.

Also add some missing punctuation to virStreamSend's documentation.

Even though rpc uses 'unsigned int' for the _len parameter that
passes the length of item<length>, the public libvirt APIs all
use 'int' and filter out lengths < 0, except for virDomainSendKey.

* include/libvirt/libvirt.h.in (virDomainSendKey): All other APIs
use int for array length.
* src/libvirt.c (virDomainSendKey): Adjust.
* src/driver.h (virDrvDomainSendKey): Likewise.
* daemon/remote_generator.pl: Likewise.

Detected by autobuild.sh, when targetting mingw.
Introduced in commit 98bfdff1.

* src/libvirt_private.syms: Fix typos.

Detected by autobuild.sh when cross-building for mingw.
Introduced in commits ce76e853 and af35cece.

* src/nodeinfo.c (nodeGetCPUStats, nodeGetMemoryStats): Mark
parameters as potentially unused.

Commit 64000eab is part 1, that only covered the daemon side by
accident. Part 2 covers the client side too.

Also improve wording of some comments.

The position of the struct parameter in the function signature
differs. Instead of hardcoding the handling for this add an annotation
to the .x file to define the position.

Based on a patch by Lai Jiangshan.

The LXC driver networking uses veth device pairs. These can
be easily hooked into the network filtering code.

* src/lxc/lxc_driver.c: Add calls to setup/teardown nwfilter

The algorithm for autoassigning vethXXX devices, was always
skipping over the starting dev index when finding a free
name for the guest device. This should only be done if the host
device was autoallocated.

* src/lxc/veth.c: Don't skip over veth indexes

Prefer bootindex=N option for -device over the old way -boot ORDER
possibly accompanied with boot=on option for -drive. This gives us full
control over which device will actually be used for booting guest OS.
Moreover, if qemu doesn't support boot=on, this is the only way to boot
of certain disks in some configurations (such as virtio disks when used
together IDE disks) without transforming domain XML to use per device
boot elements.

When an operation started by virDomainBlockPullAll completes (either with
success or with failure), raise an event to indicate the final status.  This
allows an API user to avoid polling on virDomainBlockPullInfo if they would
prefer to use the event mechanism.

* daemon/remote.c: Dispatch events to client
* include/libvirt/libvirt.h.in: Define event ID and callback signature
* src/conf/domain_event.c, src/conf/domain_event.h,
  src/libvirt_private.syms: Extend API to handle the new event
* src/qemu/qemu_driver.c: Connect to the QEMU monitor event
  for block_stream completion and emit a libvirt block pull event
* src/remote/remote_driver.c: Receive and dispatch events to application
* src/remote/remote_protocol.x: Wire protocol definition for the event
* src/qemu/qemu_monitor.c, src/qemu/qemu_monitor.h,
  src/qemu/qemu_monitor_json.c: Watch for BLOCK_STREAM_COMPLETED event
  from QEMU monitor

virDomainBlockPullAll and virDomainBlockPullAbort are handled automatically.
virDomainBlockPull and virDomainBlockPullInfo require manual overrides since
they return a custom type.

  manual overrides

Define two new virsh commands:
 * blockpull: Perform block pull operations (incremental plus start
              and stop continuous streams)
 * blockpullinfo: Retrieve progress info for continuous block pull

Share print_job_progress() with the migration code.

* tools/virsh.c: implement the new commands

The virDomainBlockPull* family of commands are enabled by the
'block_stream' and 'info block_stream' qemu monitor commands.

* src/qemu/qemu_driver.c src/qemu/qemu_monitor_text.[ch]: implement disk

Set up the types for the block pull functions and insert them into the
virDriver structure definition.  Symbols are exported in this patch to prevent
documentation compile failures.

* include/libvirt/libvirt.h.in: new API

From a security pov copy and paste between the guest and the client is not
always desirable. So we need to be able to enable/disable this. The best place
to do this from an administration pov is on the hypervisor, so the qemu cmdline
is getting a spice disable-copy-paste option, see bug 693645. Example qemu
invocation:
qemu -spice port=5932,disable-ticketing,disable-copy-paste

since the testfiles assume a /proc/cpuinfo specific to this
architecture. We e.g. can't parse the number of cores on other
architectures.

Drivers load running persistent and transient domain configs before
inactive persistent domain configs, however only the latter would set a
domain's autostart flag. This mismatch between the loaded and on-disk
state could later cause problems with "virsh autostart":

  # virsh autostart example
  error: Failed to mark domain example as autostarted
  error: Failed to create symlink '/etc/libvirt/qemu/autostart/example.xml to '/etc/libvirt/qemu/example.xml': File exists

This patch ensures the autostart flag is set correctly even when the
domain is already defined.
