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.
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.

This almost reverts b7200d7236. The size is increased from 11M to 13M
and the compression is sped up from 2 minutes to 17 seconds. The
compression level is removed because -9 doesn't allow multiple threads
to be spawned. Effectively speeds up distcheck as well.

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
d4d32005d6.
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
password expiration to "now".

libvirt.spec.in: drop Fedora < 20 and RHEL < 6
Similarly to what virsh virt-login-shell do, call virAdmInitialize prior to
initializing an event loop and initializing the error handler. Commit 97973ebb7
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
slightly enhanced analogically to virInitialize.

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.

Commit cf0568b0af moved a bunch of functions from virNetDev
to the more specific virNetDevIP; however, not all of the
existing uses were moved properly, causing build failures on
FreeBSD.
Complete the transition to the new names and drop the
obsolete declarations from the header file while at it.
Not including the header causes
util/virnetdevip.c:520:5: error:

When a client connects, it is placed into a queue. As soon as it
authenticate, it is taken out of that queue and placed into a
different one. Now, we have a setting in the daemon config file
that allows users to control the length of the queue of yet not
authenticated clients. By default, it has a value 20 but in the
description to the config knob we clam it's zero.

This is place as a sub-element of <source>, where other aspects of the
host-side connection to the network device are located (network or
bridge name, udp listen port, etc). It's a bit odd that the interface
we're configuring with this info is itself named in <target dev='x'/>,
but that ship sailed long ago:
<interface type='ethernet'>
<mac address='00:16:3e:0f:ef:8a'/>
<source>
<ip address='192.168.122.12' family='ipv4'
prefix='24' peer='192.168.122.1'/>
<ip address='192.168.122.13' family='ipv4' prefix='24'/>
<route family='ipv4' address='0.0.0.0'
gateway='192.168.122.1'/>
<route family='ipv4' address='192.168.124.0' prefix='24'
gateway='192.168.124.1'/>
</source>
</interface>
In practice, this will likely only be useful for type='ethernet', so
its presence in any other type of interface is currently forbidden in
the generic device Validate function (but it's been put into the
general population of virDomainNetDef rather than the
ethernet-specific union member so that 1) we can more easily add the
capability to other types, and 2) we can retain the info when set to
an invalid interface type all the way through to validation and report
a proper error, rather than just ignoring it (which is currently what
happens for many other type-specific settings).
(NB: The already-existing configuration of IP info for the guest-side
of interfaces is in subelements directly under <interface>, and the
name of the guest-side interface (when configurable) is in <guest
dev='x'/>).
The peer attribute is used to set the property of the same name in the
interface IP info:
<interface type='ethernet'>
...
<ip family='ipv4' address='192.168.122.5'
prefix='32' peer='192.168.122.6'/>
...
</interface>
Note that this element is used to set the IP information on the
*guest* side interface, not the host side interface - that will be
supported in an upcoming patch.

This patch takes the code out of
lxcContainerRenameAndEnableInterfaces() that adds all IP addresses and
IP routes to the interface, and puts it into a utility function
virNetDevIPInfoAddToDev() in virnetdevip.c so that it can be used by
anyone.
One small change in functionality -
lxcContainerRenameAndEnableInterfaces() previously would add all IP
addresses to the interface while it was still offline, then set the
interface online, and then add the routes. Because I don't want the
utility function to set the interface online, I've moved this up so
the interface is first set online, then IP addresses and routes are
added. This is the same order that the network service from
initscripts (in ifup-ether) does it, so it shouldn't pose any problem
(and hasn't, in the tests that I've run).
