The 'shape' attribute on <a> is used together with a 'coords'
attribute to create hot-zones in image maps. We're not using
image maps so our inclusion of a 'shape' attribute is bogus.
Furthermore this is forbidden in HTML5.

The HTML5 doctype is simply
<!DOCTYPE html>
no DTD is present because HTML5 is no longer defined as an
extension of SGML.
XSL has no way to natively output a doctype without a public
or system identifier, so we have to use an <xsl:text> hack
instead.

We have files which use HTML entities for decorating letters
with unlauts, accents, etc. Other files just use UTF-8
characters directly for this. Remove the HTML entities since
they have no benefit and use UTF-8 instead.

Some docs pages were using <p> </p> to add arbitrary whitespace
in the page. This is something that should be done by CSS if needed,
but it is not needed here, so delete it.
There was also use of <td> </td> which adds no value at all
when we have CSS to prettify tables.

We already require libxml to be installed, so it is not unreasonable
to require xmllint and xsltproc to be installed too - any platform

The HTML pages are currently validated against an XHTML 1.0 DTD.
This makes it impossible to take advantage of features that are
introduced in HTML 5, because they'll fail validation.
There is intentionally no DTD defined for HTML 5, so there's no
alternative to XHTML 1.0 DTD that we could switch to. The only
options are to stick with XHTML 1.0 forever, or drop the DTD
validation, and we pick the latter.

After an OOM error, virBuffer* APIs set buf->use to zero.
Adding a buffer to the parent buffer only if use is non-zero
would quietly drop data on error.
Check the error beforehand to make sure buf->use is zero
because we have not attempted to add anything to it.
Convert virDomainSmartcardDefFormat to use a separate buffer
for possible subelements, to avoid the need for duplicated
formatting logic in virDomainDeviceInfoNeedsFormat.
This function has grown to format more than just the address.
Delete the comment completely to avoid failing to update it
in the future.
Also, the indentation is now handled by the virBuffer APIs,
so the comment about indentation no longer makes sense.
This function returns false if virDomainDeviceInfoFormat
would not format anything.
Using it as the sole condition to decide whether to call
virDomainDeviceInfoFormat or not is pointless, since
the conditions are repeated in virDomainDeviceInfoFormat.
Not every platform is guaranteed to have dlopen/dlsym, so we should
conditionalize its use. Suprisingly it is actually present for Win32
via the mingw-dlfcn add on, but we should still conditionalize it.

This commit adds the unix socket URL support to 'domdisplay' command.
Before, even if an user was using unix socket to define a spice graphics,
the command 'domdisplay' showed that the settings were not supported. Now,
the command shows the proper URL: spice+unix://foo/bar.sock.
Settings:
<graphics type='vnc' port='-1' autoport='yes' listen='127.0.0.1'>
<listen type='address' address='127.0.0.1'/>
</graphics>
<graphics type='spice'>
<listen type='socket' socket='/tmp/spice.sock'/>
</graphics>
Before:
virsh # domdisplay --all Windows7

After:
virsh # domdisplay --all Windows7
vnc://127.0.0.1:0

So there are couple of issues here. Firstly, we never unref the
@pendingReply and thus it leaks.

Secondly, while we send the message, we are suspended ('cos we're
talking to a UNIX socket). However, until we are resumed back
again the reply might have came therefore subsequent
dbus_pending_call_set_notify() has no effect and in fact the
virNetDaemonGotInhibitReply() callback is never called. Thirdly,
the dbus_connection_send_with_reply() has really stupid policy
for return values. To cite the man page:
Returns
FALSE if no memory, TRUE otherwise.
Yes, that's right. If anything goes wrong and it's not case of
OOM then TRUE is returned, i.e. you're trying to pass FDs and
it's not supported, or you're not connected, or anything else.
Therefore, checking for return value of
dbus_connection_send_with_reply() is not enoguh. We also have to
check if @pendingReply is not NULL before proceeding any further.

Prior to qemu 2.5 the node names would not be generated, thus would be
missing from 'query-blockstats' and 'query-named-block-nodes'. Test that
the code correctly detects nothing.
Additionally make sure that a VM without disks does not cause problems.
The test case change is necessary as our test file checker does not play
well with empty files.
Treat an NULL string equivalent to an empty string in
virTestCompareToFile so that callers don't need to add additional logic
in case when a test produces no output.
'virt-aa-helper' is compiled when both WITH_LIBVIRTD and
WITH_SECDRIVER_APPARMOR are defined. The test was run only when
WITH_SECDRIVER_APPARMOR was defined thus causing a build failure when
building without the daemon.
Commit @4cb719b2dc moved the driver locks around since these have become
unnecessary at spots where the code handles now self-lockable object
list, but missed the possible double unlock if udevEnumerateDevices
fails, because at that point the driver lock had been already dropped.
