As it turns out, the rather complicated structure that is
currently used for enabling or disabling features in the libvirt
build does not cleanly map well to RPM's bcond feature.
Consequently, we need these back in order to support trivially
activating these features through extra macros as build inputs.
This reverts commit 31d687a321.

When trying to figure out whether virt-ssh-helper is available
on the remote host, we mistakenly look for the helper by the
name it had while the feature was being worked on instead of
the one that was ultimately picked, and thus end up using the
netcat fallback every single time.

In recent commit v6.8.0-135-g518be41aaa the formatting of NBD
into migration cookie was moved into a separate function and with
it it was switched from direct printing into the output buffer to
virXMLFormatElement(). But there was a typo. The
virXMLFormatElement() accepts two buffers on input, one for
element attributes and another for child elements. Well, the line
that was supposed to add NBD port into the attributes buffer
printed the attribute directly into the output buffer which
produced this mangled XML:
<qemu-migration>
port='49153'<nbd>
<disk target='vda' capacity='8589934592'/>
<disk target='vdb' capacity='12746752000'/>
</nbd>
</qemu-migration>
Changing the incriminated line to print into the attributes
buffer fixes the problem.

In one of recent patches the way that we start NBD server for
incoming migration was reworked (v6.8.0-rc1~298). A new boolean
was introduced that tracks whether the NBD server was started so
that we don't start it twice nor record in the port in the port
allocator twice. Well, this idea is good, but in the
implementation the boolean is never set, so we are reserving the
port twice and would be starting the NBD server twice too if it
wasn't for port reservation fail.

The current udev node device driver ignores all events related to vdpa
devices. Since libvirt now supports vDPA network devices, include these
devices in the device list.
Example output:
virsh # nodedev-list
[...ommitted long list of nodedevs...]
vdpa_vdpa0
virsh # nodedev-dumpxml vdpa_vdpa0
<device>
<name>vdpa_vdpa0</name>
<path>/sys/devices/vdpa0</path>

<driver>
<name>vhost_vdpa</name>
</driver>
<capability type='vdpa'>
<chardev>/dev/vhost-vdpa-0</chardev>
</capability>
</device>
NOTE: normally the 'parent' would be a PCI device instead of 'computer',
but this example output is from the vdpa_sim kernel module, so it
doesn't have a normal parent device.

Use of the -enable-fips option is being deprecated in QEMU >= 5.2.0. If
FIPS compliance is required, QEMU must be built with libcrypt which will
unconditionally enforce it.
Thus there is no need for libvirt to pass -enable-fips to modern QEMU.
Unfortunately there was never any way to probe for -enable-fips in the
first instance, it was enabled by libvirt based on version number
originally, and then later unconditionally enabled when libvirt dropped
support for older QEMU. Similarly we now use a version number check to
decide when to stop passing -enable-fips.
Note that the qemu-5.2 capabilities are currently from the pre-release
version and will be updated once qemu-5.2 is released.

This function had a loop that was only executed twice; it was
artificially constructed with a label, a goto, and a boolean to tell
that it had already been executed once. Aside from that, the body of
the loop contained only two lines that needed to be repeated (the
second time through, everything beyond those two lines would be
skipped).
One side effect of this strange loop was that a g_autofree string was
manually freed and re-initialized; I've been told that manually
freeing a g_auto_free object is highly discouraged.
This patch refactors the function to simply repeat the 2 lines that
might possibly be executed twice, thus eliminating the ugly use of
goto to construct a loop, and also takes advantage of the fact that
virPCIDriverDir() was previously returning *exactly* the same string
both times it was called to eliminate the manual VIR_FREE of drvpath.
