The tests which match the disk bus to the controller type were backwards
in this function. This meant that any disk bus type (such as
VIR_DOMAIN_DISK_BUS_SATA) would not skip the controller index comparison
even if the removed controller was of a different type.
Switch the internals to a switch statement with selects the controller
type in the first place and a proper type so that new controller types
are added in the future.

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().

This patch also changes functionality a bit.
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
is fixed now.

Some CPUs provide a way to read exact TSC frequency, while measuring it
is required on other CPUs. However, measuring is never exact and the
result may slightly differ across reboots. For this reason both Linux
kernel and QEMU recently started allowing for guests TSC frequency to
fall into +/- 250 ppm tolerance interval around the host TSC frequency.
Let's do the same to avoid unnecessary failures (esp. during migration)
in case the host frequency does not exactly match the frequency
configured in a domain XML.

There are two types of vhostuser ports:
dpdkvhostuser - OVS creates the socket and QEMU connects to it
dpdkvhostuserclient - QEMU creates the socket and OVS connects to it
But of course ovs-vsctl syntax for fetching ifname is different.
So far, we've implemented the former. The lack of implementation
for the latter means that we are not detecting the interface name
and thus not reporting it in domain XML, or failing to get
interface statistics.

A qemu guest which has virtiofs config fails to start if the previous
starting failed because of invalid option or something.
That's because the virtiofsd isn't killed by virPidFileForceCleanupPath()
on the former failure because the pidfile was already removed by
virFileDeleteTree(priv->libDir) in qemuProcessStop(), so
virPidFileForceCleanupPath() just returned.
Move qemuExtDevicesStop() before virFileDeleteTree(priv->libDir) so that
virPidFileForceCleanupPath() can kill virtiofsd correctly.
For example of the reproduction:
# virsh start guest
error: Failed to start domain guest
error: internal error: process exited while connecting to monitor: qemu-system-x86_64: -foo: invalid option
... fix the option ...
# virsh start guest
