virConnectDomainEventRegisterAny() takes a domain as an argument.
So it should be possible to register the same event (be it
VIR_DOMAIN_EVENT_ID_LIFECYCLE for example) for two different domains.
That is, we need to take domain into account when searching for
duplicate event being already registered.

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.

For the s390x architecture the sysfs core_id alone is not unique. As a
result it can happen that libvirt thinks there are less host CPUs available
than really present.
Currently, a logical CPU is equivalent to a core for s390x. We therefore
produce a fake core id from the CPU number.

Starting a KVM guest on s390 fails immediately. This is because
"qemu --help" reports -no-acpi even for the s390(x) architecture but
-no-acpi isn't supported there.
Workaround is to remove QEMU_CAPS_NO_ACPI from the capability set
after the version/capability extraction.

We used to prefix 'rbd:' to volume names, this is not necessary.

Qemu takes RBD devices in this way, like: qemu -drive rbd:pool/image

When attaching a network disk like RBD to a guest we however do not use this prefix.

Currently you can't map a RBD volume name directly to a domain without removing the prefix.

"cannot set memory of an active domain" is misleading, it sounds
like setting memory of active domain is not supported.

If no 'listen' attribute or <listen> element is set in the
guest XML, the default driver configured listen address is
used. There is no way to client applications to determine
what this address is though. When starting the guest, we
should update the live XML to include this default listen
address

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.

Currently, we share the idea of old & new def with domains. Users can
*-edit an object (domain, pool) which spawns a new internal
representation for them. This is referenced via
{domainObj,poolObj}->newDef [compared to ->def]. However, for pool we
were never overwriting def with newDef. This must be done on
pool-destroy (like we do analogically in domain detroy).

One of latest patches (0fce94fe) didn't properly indented #define
making syntax-check fail.

Temporary fix since compilation broke with older version of
sanlock following acbd4965

Currently libvirt-lxc checks to see if the destination exists and is a
directory.  If it is not a directory then the mount fails.  Since
libvirt-lxc can bind mount files on an inode, this patch is needed to
allow us to bind mount files on files.  Currently we want to bind mount
on top of /etc/machine-id, and /etc/adjtime

If the destination of the mount point does not exists, it checks if the
src is a directory and then attempts to create a directory, otherwise it
creates an empty file for the destination.  The code will then bind mount
over the destination.

must be included before windows.h. This means that any file
which does

  #include <windows.h>

Currently you can configure LXC to bind a host directory to
a guest directory, but not to bind a guest directory to a
guest directory. While the guest container init could do
this itself, allowing it in the libvirt XML means a stricter
SELinux policy can be written

Introduce a new syntax for filesystems to allow use of a RAM
filesystem

   <filesystem type='ram'>
      <source usage='10' units='MiB'/>
      <target dir='/mnt'/>
   </filesystem>

The usage units default to KiB to limit consumption of host memory.

The test of ref count is not protected by lock, which is unsafe because
the ref count may have been changed by other threads during the test.

This patch fixes this.

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.

When shutting down libvirtd, the virNetServer shutdown can deadlock
if there are in-flight jobs being handled by virNetServerHandleJob().
virNetServerFree() will acquire the virNetServer lock and call
virThreadPoolFree() to terminate the workers, waiting for the workers
to finish.  But in-flight workers will attempt to acquire the
virNetServer lock, resulting in deadlock.

Fix the deadlock by unlocking the virNetServer lock before calling
virThreadPoolFree().  This is safe since the virNetServerPtr object
is ref-counted and only decrementing the ref count needs to be
protected.  Additionally, there is no need to re-acquire the lock
after virThreadPoolFree() completes as all the workers have
terminated.

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.

The comment says:

/* Now create the final dir in the path with the uid/gid/mode
 * requested in the config. If the dir already exists, just set
 * the perms.
 */

However, virDirCreate is only invoked if the target path doesn't
exist yet (which is opposite with the comment), or the uid from
the config is not -1 (I don't understand why, think it's just
another mistake). And the result is the perms of the pool won't
be changed if one tries to build the pool with different perms
again.

Besides these logic error fix, if no uid and gid are specified in
the config, the practical used uid, gid are reflected.

The two new APIs are rather trivial; based on bits and pieces of
other existing APIs.  But rather than blindly return 0 or 1 for
