Using 'haveTLS' to do this is pointless if the alias is not set.

Now that we remember the alias we've used to attach the secret objects
we should reuse them rather than trying to infer them from the disk
configuration.

Previously we did not store the aliases but rather re-generated them
when unplug was necessary. This is very cumbersome since the knowledge
when and which alias to use needs to be stored in the hotplug code as
well.
While this patch will not strictly improve this situation since there
still will be two places containing this code it at least will allow to
remove the mess from the disk-unplug code and will prevent introducing
more mess when adding blockdev support.

Commit 656151bf fixed formatting of the <cmdline> element. Perhaps it
would have been noticed and fixed earlier if we had a test. With this
change, all possible cases of formatting <cmdline> from xmconfig are
covered
1. no 'extra=' or 'root=' in xm.cfg
2. 'extra=' but no 'root=' in xm.cfg
3. 'root=' but no 'extra=' in xm.cfg
4. both 'root=' and 'extra=' in xm.cfg
Case 1 is covered by all existing paravirt tests since they have no
'extra=' or 'root='. Case 2 is covered by adding 'extra=' to a few
of the existing paravirt tests. Cases 3 and 4 are covered by new
tests that only test conversion of xm.cfg to xml.

Per-domain log files were introduced in commit a30b08b717. The FILE
objects associated with these log files are stored in a hash table
using domid as a key. When a domain is shutdown, destroyed, or
otherwise powered-off, the FILE object is removed from the hash table,
where the free function will close the FILE.
Unfortunately the call to remove the FILE from the hash table occurs
after setting domid=-1 in the libxlDomainCleanup() function. The
object is never removed from the hash table, the free function is
never called, and the underlying fd is leaked. Fix by removing the
FILE object from the hash table before setting domid=-1.

Reviewed-by: Ján Tomko <jtomko@redhat.com>
In commit 8bebb2b735 I've refactored how the detach of disk with a
managed persistent reservations object is handled. After the commit if
any disk with a managed PR object would be removed libvirt would also
attempt to remove the shared 'pr-manager-helper' object potentially used
by other disks.
Thankfully this should not have practical impact as qemu should reject
deletion of the object if it was still used and the rest of the code is
correct.
Fix this by removing the disk from the definition earlier and checking
if the shared/managed pr-manager-helper object is still needed.
This basically splits the detach code for the managed PR object from the
unmanaged ones. The same separation will follow for the attachment code
as well as it greatly simplifies -blockdev support for this.

When preparing qemuCaps for test cases the following is
happening:
qemuTestParseCapabilitiesArch() is called, which calls
virQEMUCapsLoadCache() which in turn calls
virQEMUCapsInitHostCPUModel() which sets qemuCaps->kvmCPU and
qemuCaps->tcgCPU.
But then the code tries to update the capabilities:
testCompareXMLToArgv() calls testUpdateQEMUCaps() which calls
virQEMUCapsInitHostCPUModel() again overwriting previously
allocated memory. The solution is to free host cpuData in
testUpdateQEMUCaps().

The nwfilter XMLs in /etc are defined as %ghost in the spec file, which
means rpm will not install them, but it will record its existence and
permissions in the database. During installation the files are copied in
a %post scriptlet from /usr/share/libvirt/nwfilter, but once libvirtd is
restarted, it will rewrite the files to add generated UUIDs.
While RPM recorded 644 mode for the XMLs, libvirt saves them with 600
and thus any future attempt to verify the libvirt-daemon-config-nwfilter
package would fail. We need to tell RPM the ghost files are supposed to
have 600 permissions.
