Add a new secret type known as "passphrase" - it will handle adding the
secret objects that need a passphrase without a specific username.

The format is:

   <secret ...>
     <uuid>...</uuid>

     <usage type='passphrase'>
       <name>mumblyfratz</name>

Since the virSecretDefParseUsage ensures each of the fields is present,
no need to check during virSecretDefFormatUsage (also virBufferEscapeString

    This replicates the metadata field found in the domain configuration
    and adds it to the network configuration XML.

This is a generic version of virDomainDefMetadataSanitize() - the same
functionality is now needed for network metadata.

I can't think of any good reason to do either of those, and having the
examples there will just lead to unusable patch emails from people who
can't be bothered to read the entire page.

Remove the local kvmpath variable from
virHostCPUGetThreadsPerSubcore() and use the file-global
KVM_DEVICE define instead.

On error, asprintf returns -1 and the contents of the string
pointer is undefined. In the rest of the libvirt code,
the virAsprintf wrapper takes care of that.

Check the return value and report a generic error, since we
purposefully avoid linking to virutil.

The default Fedora build roots for f25 and newer no longer
include perl. We must thus explicitly ask for it as the
RPC gendispatch.pl program needs it, and the Getopt::Long
module. Do this unconditionally since it isn't harmful for
older Fedora

Since it's not strictly a uuid anymore

This allows event implementations to match on something other
than an object's uuid, like nodedev or interface objects which
don't have a uuid.

This should not have any functional difference, it's just a step
towards matching on non-uuid string keys

In every other instance virObjectEventCallbackPtr is named 'cb',
and in other code 'event' usually means a virObjectEventPtr

It's only used in object_event.c, so remove it from the header. We
need to move the _virObjectEventCallback definition earlier as a
result.

A helper that will execute a callback on every USB device
in the domain definition.

With an ability to skip USB hubs, since we will want to treat
them differently in some cases.

This test assumes the XML will be the same after formatting.
Add USB addresses to it to keep it working when we autoassign them.

I'm not sure why our code claimed "-boot menu=on" cannot be used in
combination with per-device bootindex, but it was proved wrong about
four years ago by commit 8c952908. Let's always use bootindex when QEMU
supports it.

virTypedParameterAssign steals the string rather than copying it into
the typed parameter and thus freeing it leads to a crash when attempting
to serialize the results.

This was introduced in commit 9f50f6e2 and later made an universal
helper in 32e6339c.

Some code paths already assume that it is allocated since it was always
allocated by virDomainPerfDefParseXML. Make it member of virDomainDef
directly so that we don't have to allocate it all the time.

This fixes crash when attempting to connect to an existing process via
virDomainQemuAttach since we would not allocate it in that code path.

The commit "qemu: hot-plug: Assume support for -device in
qemuDomainAttachSCSIDisk" dropped the code for the automatic SCSI
controller creation used in SCSI disk hot-plugging. If we are
hot-plugging a SCSI disk to a domain and there is no proper SCSI
controller defined, it results in an "error: internal error: Could not
find scsi controller with index X required for device" error.

For that reason reverting a hunk of the commit
d4d32005.

This patch also adds an extra comment to the code to clarify the
loop.

CVE-2016-5008

Setting an empty graphics password is documented as a way to disable
VNC/SPICE access, but QEMU does not always behaves like that. VNC would
happily accept the empty password. Let's enforce the behavior by setting

Similarly to what virsh virt-login-shell do, call virAdmInitialize prior to
initializing an event loop and initializing the error handler. Commit 97973ebb
described and fixed an identical issue for libvirt_lxc.
Since virAdmInitialize becomes a public API after applying this patch,
the symbol is also added to public syms and the doc string of the method is

virNetServerClientGetInfo returns the client's remote address
as a string, which is a part of the client object.

Use VIR_STRDUP to make a copy which can be freely accessed
even after the virNetServerClient object is unlocked.

To reproduce, put a sleep between virObjectUnlock in
virNetServerClientGetInfo and virTypedParamsAddString in
adminClientGetInfo, then close the queried connection during
that sleep.

Consider the following disk for a domain:

    <disk type='volume' device='cdrom'>
      <driver name='qemu' type='raw'/>
      <auth username='libvirt'>
        <secret type='iscsi' usage='libvirtiscsi'/>
      </auth>
      <source pool='iscsi-secret-pool' volume='unit:0:0:0' mode='direct' startupPolicy='optional'/>
      <target dev='sda' bus='scsi'/>
      <readonly/>
      <address type='drive' controller='0' bus='0' target='0' unit='0'/>
    </disk>

Now, startupPolicy is currently not allowed for iscsi disks, so
one would expect an error message to be thrown. But what a
surprise is waiting for users if they try to start up such
domain:

The problem is, in virStorageTranslateDiskSourcePool disk
def->src->auth is freed, but the pointer is not set to NULL. So
later, when qemuProcessStop starts to free the domain definition,
virStorageAuthDefFree() tries to free the memory again, instead
of jumping out immediately.
