The migration stream connection and also the NBD server for non-shared
storage migration don't have any other form of client authentication on
top of the TLS transport, so the only way to authenticate clients is to
verify their certificate.
Enable this option by defauilt when both 'migrate_tls_x509_verify' and
'default_tls_x509_verify' were not configured.

If both "vnc_tls_x509_verify" and "default_tls_x509_verify" are missing
from the config file the client certificate validation is disabled. VNC
provides a layer of authentication so client certificate validation is

Switch the internals to a switch statement with selects the controller

page.xsl was adding '<div id="content">' wrapper for the content picked
up from the <body> element from the original input file. Optionally
class="$DOCNAME" was added for some documents taken from <body>.
Since docs generated from RST by docutils have a '<div class='document'
id='$DOCNAME>' we actually don't need an extra wrapper for them.
Additionally if we standardize on one of them we can use the same styles
for both. I've picked the latter because it makes more sense to use the
document name as 'id'.
This patch:
1) Modifies the XSL trasformation to add the wrapper only if it's not
present.
2) Modifies the XSL transformation to use 'id' for document name and
class='document' for the wrapper element.
3) Changes docs.html/index.html/hvsupport.html to use 'id' instead of
'class' for document name.
4) Modifies the main stylesheet to keep styling the elements properly

While it's certainly good to log events like "failed to close fd"
and "tried to close invalid fd", which are likely to be the
consequence of some bug in libvirt, logging a message every single
time a file descriptor is closed successfully is perhaps excessive
and can lead to useful information being missed among the noise.
Log filters don't help in this situation, because filtering out all
of util.file is too big a hammer and would cause important messages
to be left out as well.
To give an idea of just how much noise this single debug statement
can cause, here's a real life example from a quite large libvirtd
log I had to look at recently:
$ grep virFile libvirt.log | wc -l
1307
$ grep virFile libvirt.log | grep -v 'Closed fd' | wc -l
343

Before commit 24d8968c, virDirClose took a DIR**, and that was never
NULL, so its declaration included ATTRIBUTE_NONNULL(1). Since that
commit, virDirClose takes a DIR*, and it may be NULL (e.g. if the DIR*
is initialized to NULL and was never closed).
Even though virDirClose() is currently only called implicitly (as the
cleanup for a g_autoptr(DIR)), and (as I've just newly learned) the
autocleanup function g_autoptr will only be called if the pointer in
question is non-null (see the definition of
_GLIB_AUTOPTR_CLEAR_FUNC_NAME in
/usr/include/glib-2.0/glib/gmacros.h), it does still cause Coverity to
complain that it *could* be called with a NULL, and it's also possible
that in the future someone might add code that explicitly calls
virDirClose.
To eliminate the Coverity complaints, and protect against the
hypothetical future where someone both explicitly calls virDirClose()
with a potentially NULL value, *and* re-enables the nonnull directive
when not building with Coverity (disabled by commit eefb881) this
patch removes the ATTRIBUTE_NONNULL(1) from the declaration of
virDirClose().

First if unlinking of old config file is failed we rollback and return error
previously and now we return success. I don't think this makes much difference.
I guess in both cases on libvirtd restart we have to deal with both new and old
config existing on disk with different names but same uuid.
Second if unlinking of old autolink is failed we rollback previously which
was not right as at this point we already unlink old config file. So this
