Adding the default bus type ISA to the message.

The default USB controller is not sent to destination as the older versions
of libvirt(0.9.4 or earlier as I see in commit log of 409b5f54) didn't
support them. For some archs where the support started much later can
safely send the USB controllers without this worry. So, send the controller
to destination for all archs except x86. Moreover this is not very applicable
to x86 as the USB controller has model ich9_ehci1 on q35 and for pc-i440fx,
there cant be any slots before USB as it is fixed on slot 1.

The patch fixes a bug that, if the USB controller happens to occupy
a slot after disks/interfaces and one of them is hot-unplugged, then
the default USB controller added on destination takes the smallest slot
number and that would lead to savestate mismatch and migration
failure. Seen and verified on PPC64.

We had both and the only difference was that the latter also included
information about multifunction setting.  The problem with that was that
we couldn't use functions made for only one of the structs (e.g.
parsing).  To consolidate those two structs, use the one in virpci.h,
include that in domain_conf.h and add the multifunction member in it.

Rather than take username and password as parameters, now take
a qemuDomainSecretInfoPtr and decode within the function.

NB: Having secinfo implies having the username for a plain type
    from a successful virSecretGetSecretString

Similar to the qemuDomainSecretDiskPrepare, generate the secret
for the Hostdev's prior to call qemuProcessLaunch which calls
qemuBuildCommandLine. Additionally, since the secret is not longer
added as part of building the command, the hotplug code will need
to make the call to add the secret in the hostdevPriv.

Since this then is the last requirement to pass a virConnectPtr
to qemuBuildCommandLine, we now can remove that as part of these
changes. That removal has cascading effects through various callers.

Modeled after the qemuDomainDiskPrivatePtr logic, create a privateData
pointer in the _virDomainHostdevDef to allow storage of private data
for a hypervisor in order to at least temporarily store auth/secrets
data for usage during qemuBuildCommandLine.

NB: Since the qemu_parse_command (qemuParseCommandLine) code is not
expecting to restore the auth/secret data, there's no need to add
code to handle this new structure there.

Updated copyrights for modules touched. Some didn't have updates in a

Rather than needing to pass the conn parameter to various command
line building API's, add qemuDomainSecretPrepare just prior to the
qemuProcessLaunch which calls qemuBuilCommandLine. The function
must be called after qemuProcessPrepareHost since it's expected
to eventually need the domain masterKey generated during the prepare
host call. Additionally, future patches may require device aliases
(assigned during the prepare domain call) in order to associate
the secret objects.

The qemuDomainSecretDestroy is called after the qemuProcessLaunch
finishes in order to clear and free memory used by the secrets
that were recently prepared, so they are not kept around in memory
too long.

Placing the setup here is beneficial for future patches which will
need the domain masterKey in order to generate an encrypted secret
along with an initialization vector to be saved and passed (since
the masterKey shouldn't be passed around).

Finally, since the secret is not added during command line build,
the hotplug code will need to get the secret into the private disk data.

Introduce a new private structure to hold qemu domain auth/secret data.
This will be stored in the qemuDomainDiskPrivate as a means to store the
auth and fetched secret data rather than generating during building of
the command line.

The initial changes will handle the current username and secret values
for rbd and iscsi disks (in their various forms). The rbd secret is
stored as a base64 encoded value, while the iscsi secret is stored as
a plain text value. Future changes will store encoded/encrypted secret
data as well as an initialization vector needed to be given to qemu
in order to decrypt the encoded password along with the domain masterKey.
The inital assumption will be that VIR_DOMAIN_SECRET_INFO_PLAIN is
being used.

Although it's expected that the cleanup of the secret data will be
done immediately after command line generation, reintroduce the object
dispose function qemuDomainDiskPrivateDispose to handle removing
memory associated with the structure for "normal" cleanup paths.

After killing one of the conditionals it's now guaranteed to have
@drivealias populated when calling the monitor, so the code attempting
to cleanup can be simplified.

Code was obsoleted by using -device.

Commit 98c5c53d partially reverted the effort to use typecasted enums
for compiler notification. Turn it back.

At that point the perf events struct should not be allocated so there's
no use in clearing it.

For strange reasons if a perf event type was not supported or failed to
be enabled at VM start libvirt would ignore the failure.

On the other hand on restart if the event could not be re-enabled
libvirt would fail to reconnect to the VM and kill it.

Both don't make really sense. Fix it by failing to start the VM if the
event is not supported and change the event to disabled if it can't be
reconnected (unlikely).

Reject the VM startup if the perf event structure can't be allocated.

Since the field is internal to libvirt we can allow the users to modify
it.

Both disk->src->shared and disk->src->readonly can't be modified when
changing disk source for floppy and cdrom drives since both arguments
are passed as arguments of the disk rather than the image in qemu.

Historically these fields have only two possible values since they are
represented as XML thus we need to ignore if user did not provide them
and thus we are treating them as false.

disk->dst represents the <target> element in the XML.

If qemu doesn't support DEVICE_TRAY_MOVED event the code that attempts
to change media would attempt to re-eject the tray even if it wouldn't
be notified when the tray opened. Add a capability bit and skip retrying
for old qemus.

Empty floppy drives start with tray in "open" state and libvirt did not
refresh it after startup. The code that inserts media into the tray then
waited until the tray was open before inserting the media and thus
floppies could not be inserted.

This reverts commit 6e244c65, which
added support to qemu for the "peer" attribute in domain interface <ip>
elements.

It's being removed temporarily for the release of libvirt 1.3.4
because the feature doesn't work, and there are concerns that it may
need to be modified in an externally visible manner which could create
backward compatibility problems.

 Conflicts:
   tests/qemuxml2argvmock.c - a mock of virNetDevSetOnline() was added
   which may be assumed by other tests added since the original commit,
   so it isn't being reverted.

Similarly to what commit 71408079 did with some internal paths,
clear vnc socket paths that were generated by us.  Having such path in
the definition can cause trouble when restoring the domain.  The path is
generated to the per-domain directory that contains the domain ID.
However, that ID will be different upon restoration, so qemu won't be
able to create that socket because the directory will not be prepared.

To be able to migrate to older libvirt, skip formatting the socket path
in migratable XML if it was autogenerated.  And mark it as autogenerated
if it already exists and we're parsing live XML.

Best viewed with '-C'.

If the domain name is long enough, the timestamp can prolong the
filename for automatic coredump to more than the filesystem's limit.
Simply shorten it like we do in other places.  The timestamp helps with
the unification, but having the ID in the name won't hurt.
