The call to virReportError conditionally switched between
two format strings, with different numbers of placeholders.
This meant the format string with no placeholders was not
protected by a "%s".

Commit 7c9a2d88 cleaned up too many headers; FreeBSD builds
failed due to:

util/virutil.c:556: warning: implicit declaration of function 'canonicalize_file_name'

(Not sure which Linux header leaked this declaration, but gnulib
only guarantees it in stdlib.h)

libvirt.c:956: warning: implicit declaration of function 'virGetUserConfigDirectory'

(Here, a build on Linux was picking up virutil.h indirectly via
one of the conditional driver headers, where that driver was not
being built on my FreeBSD setup)

commit 7c9a2d88 missed adding in a few #include "virstring.h"s, causing
builds to fail.

The source code base needs to be adapted as well. Some files
include virutil.h just for the string related functions (here,
the include is substituted to match the new file), some include
virutil.h without any need (here, the include is removed), and
some require both.

It's not desired to force users imagine path for a socket they
are not even supposed to connect to. On the other hand, we
already have a release where the qemu agent socket path is
exposed to XML, so we cannot silently drop it from there.
The new path is generated in form:

$LOCALSTATEDIR/lib/libvirt/qemu/channel/target/$domain.$name

for qemu system mode, and

$XDG_CONFIG_HOME/qemu/lib/channel/target/$domain.$name

for qemu session mode.

When MAXHOSTNAMELEN is set we have to take it's value into account.
Otherwise the build fails on kFreeBSD (FreeBSD kernel and GNU userland)

virPCIDeviceReattach and virPCIDeviceUnbindFromStub (called by
virPCIDeviceReattach) had previously required the name of the stub
driver as input. This is unnecessary, because the name of the driver
the device is currently bound to can be found by looking at the link:

  /sys/bus/pci/dddd:bb:ss.ff/driver

Instead of requiring that the name of the expected stub driver name
and only unbinding if that one name is matched, we no longer take a
driver name in the arglist for either of these
functions. virPCIDeviceUnbindFromStub just compares the name of the
currently bound driver to a list of "well known" stubs (right now
contains "pci-stub" and "vfio-pci" for qemu, and "pciback" for xen),
and only performs the unbind if it's one of those devices.

This allows virsh nodedevice-reattach to work properly across a
libvirtd restart, and fixes a couple of cases where we were
erroneously still hard-coding "pci-stub" as the drive name.

For some unknown reason, virPCIDeviceReattach had been calling
modprobe on the stub driver prior to unbinding the device. This was
problematic because we no longer know the name of the stub driver in
that function. However, it is pointless to probe for the stub driver
at that time anyway - because the device is bound to the stub driver,
we are guaranteed that it is already loaded, and so that call to
modprobe has been removed.

Conditional BuildRequires: should be at the top level, rather
than appearing in conditional sub-package sections.  This
appears to be the only offender.

Commit cc6d19f3 added text containing "<code>snapshot<code>" to
formatsnapshot.html.in. The closing tag is missing '/' which causes
the documentation to misrender.

Python code generator "generate_source" section that handles
code generation to "free" inherited objects needs to generate
DISPATCH_FREE calls for all extended_by objects.

For s390 we don't want to have a default USB device generated even
if QEMU is silently tolerating -usb on the command line. This may change
in the future.
Another reason to avoid the USB controller is that it implies a PCI
bus which might cause a regression at some later point in time.
The following change will set the USB controller model to 'none'
unless a model or address has been specified, which can be the case
if a legacy definition is loaded or the XML writer knows what
she/he's doing.
Requiring the user to explicitly disable USB on systems not supporting
it seems cumbersome.

Add a line saying that no USB controllers are generated by default
on s390.

Commit eca3fdf7 inadvertantly caused a failure to start for any domain
with the following in its config:

    <graphics type='spice' autoport='yes'/>

The problem is that when tlsPort == 0 and defaultMode == "any" (which
is the default for defaultMode), this would be flagged in the code as
"needTLSPort", and if there was then no spice tls config, the new
error+fail would happen.

This patch checks for the case of defaultMode == "any", and in that
case simply doesn't allocate a TLS port (since that's probably not
what the user wanted, and it would have failed later anyway.). It does
leave the error in place for cases when the user specifically asked to
use tls in one way or another, though.

These leaks were all introduced (by me) very recently, in commit
f0bd70a9.

libxlBuildDomainConfig() was disposing the libxl_domain_config object
on error, only to have it disposed again by libxlBuildDomainConfig()'s
caller, which resulted in a segfault.  Leave disposing of the config
object to it's owner.

We already support ESX 5.1, but virtualHW version used by such
hypervisor [1] wasn't taken into account.

* the canonical long option if its argument is not

argv ourselves or let getopt print the errors, since
we can't tell long and short options apart by optopt
or longindex)

When a user requests auto-allocation of the spice TLS port but spice TLS
is disabled in qemu.conf, we start the machine and let qemu fail instead
of erroring out sooner.

Add an error message so that this doesn't happen.

On the off-chance that creation of persistent configuration file would
fail when defining a network that is already started as transient, the
code would remove the transient data structure and thus the network.

This patch changes the code so that in such case, the network is again
marked as transient and left behind.

The USB-specific cgroup setup had been inserted inline in
qemuDomainAttachHostUsbDevice and qemuSetupCgroup, but now there is a
common cgroup setup function called for all hostdevs, so it makes sens
to put the usb-specific setup there and just rely on that function
being called.

The one thing I'm uncertain of here (and a reason for not pushing
until after release) is that previously hostdev->missing was checked
only when starting a domain (and cgroup setup for the device skipped
if missing was true), but with this consolidation, it is now checked
in the case of hotplug as well. I don't know if this will have any
practical effect (does it make sense to hotplug a "missing" usb
device?)
