This patch brings support to manage sheepdog pools and volumes to libvirt.
It uses the "collie" command-line utility that comes with sheepdog for that.

A sheepdog pool in libvirt maps to a sheepdog cluster.
It needs a host and port to connect to, which in most cases
is just going to be the default of localhost on port 7000.

A sheepdog volume in libvirt maps to a sheepdog vdi.
To create one specify the pool, a name and the capacity.
Volumes can also be resized later.

In the volume XML the vdi name has to be put into the <target><path>.
To use the volume as a disk source for virtual machines specify
the vdi name as "name" attribute of the <source>.
The host and port information from the pool are specified inside the host tag.

  <disk type='network'>
    ...
    <source protocol="sheepdog" name="vdi_name">
      <host name="localhost" port="7000"/>
    </source>
  </disk>

To work right this patch parses the output of collie,
so it relies on the raw output option. There recently was a bug which caused
size information to be reported wrong. This is fixed upstream already and
will be in the next release.

Introduce new members in the virMacAddr 'class'
- virMacAddrSet: set virMacAddr from a virMacAddr
- virMacAddrSetRaw: setting virMacAddr from raw 6 byte MAC address buffer
- virMacAddrGetRaw: writing virMacAddr into raw 6 byte MAC address buffer
- virMacAddrCmp: comparing two virMacAddr
- virMacAddrCmpRaw: comparing a virMacAddr with a raw 6 byte MAC address buffer

then replace raw MAC addresses by replacing

- 'unsigned char *' with virMacAddrPtr
- 'unsigned char ... [VIR_MAC_BUFLEN]' with virMacAddr

and introduce usage of above functions where necessary.

Instead of changing the existed virFileMakePath to accept mode
argument and modifying a pile of its uses, this patch introduces
virFileMakePathWithMode, and use it instead of mkdir() to create
the readline history dir.

Clarify the docs to make more clear what this command does and that it
requires a guest agent running in the guest.

In vshSnapshotListCollect() vshCalloc was called with swapped nmemb and

v2:
- Refactored to use virBuffer
- Refactored to use virXPath wrappers
- Added support for tls-port and password for SPICE
- Added optional flag to disable SPICE password to the URI
- Added support for RDP
- Fixed code reviews

Add a new 'domdisplay' command that provides a URI for VNC, SPICE and
RDP connections. Presently the 'vncdisplay' command provides you with
the port info that QEMU is listening on but there is no counterpart for
SPICE and RDP. Additionally this provides you with the bind address as
specified in the XML, which the existing 'vncdisplay' lacks. For SPICE
connections it supports secure and unsecure channels and optionally
providing the password for the SPICE channel.

Storage is one of the last domains in libvirt where we don't fully
utilize inactive and live XML. Okay, it might be because we don't
have support for that. So implement such support. However, we need
to fallback when talking to old daemon which doesn't support this
new flag called VIR_STORAGE_XML_INACTIVE.

This patch adds a check for the count of processors the user requests
for the guest machine so that invalid values produce a more helpful
error message.

This patch makes use of the newly added api virConnectListAllDomains()
to list domains in virsh.

Virsh now represents lists of domains using an internal structure
vshDomainList. This structure contains the virDomainPtr list as provided
by virConnectListAllDomains() and the count of domains in the list.

For backwards compatibility, the function vshDomainListCollect was added
that tries to enumerate the domains using the new API and if the API is
not supported falls back to the older approach with the two list
functions.  The helper function also simulates filtering by all
currently supported flags added with virConnectListAllDomains().

This patch also cleans up the "list" command handler to use the new
helpers and adds new command line flags to make use of filtering.

Using the new API is so much shorter than the rest of the remainder
of the function.

* tools/virsh.c (vshSnapshotList): Use the new API.

Previously, to get the name of all snapshots with children, it was
necessary to get the name of all snapshots and then remove the
name of leaf snapshots.  This is racy, and somewhat inefficient
compared to planned API additions.  We can emulate --no-metadata on
0.9.5-0.9.12, but for now, there is no emulation of --no-leaves.

* tools/virsh.c (cmdSnapshotList): Add new options --no-leaves and
--no-metadata.
(vshSnapshotList): Emulate where possible.
* tools/virsh.pod (snapshot-list): Document them.

virsh help fix:
 - <--title> can also /get/ the title

virsh man page:
 - missing <domain-id>
 - <new_desc> should be <new-desc>

Append '(MAC Address)' after the help string of domiftune virsh
command as it takes the same type of argument as domif-{get,set}link
which have it specified.

as we support qed format as well.

Operating on a list of snapshot objects looks so much simpler.
In particular, since the helper function already trimmed out
irrelevant entries, we no longer have quite so many special cases
on finding the first snapshot to operate on.  Also, vshTreePrint
no longer has a generic callback struct; both clients now pass
something different according to their own needs.

* tools/virsh.c (cmdSnapshotList): Use previous patches.
(vshTreeArrayLookup): Rename...
(vshNodeListLookup): ...now that it only has one client.
(cmdNodeListDevices): Adjust caller.

This patch is based on the fallback code out of cmdSnapshotList,
with tweaks to keep the snapshot objects around rather than just
their name, and to remove unwanted elements before returning.
It looks forward to a future patch when we add a way to list all
snapshot objects at once, and the next patch will simplify
cmdSnapshotList to take advantage of this factorization.

* tools/virsh.c (vshSnapshotList, vshSnapshotListFree): New functions.

Add a new parameter --memory-only for 'virsh dump' command. So
the user can decide the vmcore's format.

There is a little easter egg in virsh: one can easily clone
an object (domain, network, ...). Just 'virsh edit' change the name
and remove <uuid>. And then, in the end when reporting success
the new name was printed out.
However, with recent edit rewrite we lost the final part and are
still printing the original name out.

When printing reedit options we make stdin raw. However,
this results in stdout being raw as well. Therefore we need
to return carriage when doing new line. Unfortunately,
'\r' cannot be part of internationalized messages hence
we must move them to formatting string which then in turn
become huge and disarranged. To solve this, a new function
is introduced which takes variable string arguments and
prepend each with "\r\n" just before printing.

The attach-disk command used with parameter --cache created an invalid
XML snippet as the beginning of the <driver> element was not printed
when used solely with --cache and no other attribute to driver.

commit 52d064f4 added
VIR_NETWORK_XML_INACTIVE in order to allow suppressing the
auto-generated list of VFs in network definitions, and a --inactive
flag to virsh net-dumpxml to take advantage of the flag. However, it
missed out on two opportunities:

1) Use INACTIVE to get the current config of the network as it
   exists on disk, rather than the currently active config.

2) Add INACTIVE to the flags used for the virsh net-edit command, so
   that it won't include the forward-pool interfaces that were
   autogenerated, and so that a re-edit of the network prior to
   restarting it will show any other edits made since the last restart
   of the network. (prior to this patch, if you edited a network a 2nd
   time without restarting, all of the previous edits would magically
   disappear).

In order to fit with the new #define-based generic edit function in
virsh.c, a new function vshNetworkGetXMLDesc() was added. This
function first tries to call virNetworkGetXMLDesc with the INACTIVE
flag added, then retries without if the first attempt fails (in the
manner expected when the server doesn't support it).
