Introduce support for
<serial type='pty'>
<target type='isa-debug'>
<model type='isa-debugcon'/>
</target>
<address type='isa' iobase='0x402'/>
</console>
which is used as a way to receive debug messages from the
firmware on x86 platforms.
Note that the default port is hypervisor specific, with QEMU
currently using 0xe9 since that's the original Bochs debug port.
For use with SeaBIOS/OVMF, the iobase port needs to be explicitly
set to 0x402.

When virNodeDeviceObjListRemove() is called, the passed
virNodeDeviceObj is removed from internal list of node devices
and then unrefed and unlocked. While the former is warranted (the
object was refed at the beginning of the function) the unlock is
not. In fact, it's wrong from conceptual POV. We still want
threads working on the object tu mutually exclude each other.

This mostly overlaps with virDomainAudioType, but in a couple of
cases the string representations are different.
Right now we're doing that in a somewhat sketchy way, in that we
store values of one enumeration and then convert them to strings
using TypeToString() implementation for the other enumeration;
when converting from string, we open-code the handling of the
special values mentioned above.
Drop the second enumeration and introduce two helpers to deal
with conversion. Most calling sites don't need to be changed, and
one can even be simplified significantly.

Currently, memory device (def->mems) part of cmd line is
generated before any controller. In majority of cases it doesn't
matter because neither of memory devices live on a bus that's
created by an exposed controller (e.g. there's no DIMM
controller, at least not exposed). Except for virtio-mem and
virtio-pmem, which do have a PCI address. And if it so happens
that the device goes onto non-default bus (pci.0) starting such
guest fails, because the controller that creates the desired bus
wasn't processed yet. QEMU processes arguments in order.
For instance, if virtio-mem has address with bus='0x01' QEMU
refuses to start with the following message:
Bus 'pci.1' not found
Similarly for virtio-pmem. I've successfully tested migration and
changing the order does not affect migration stream.

Inside the testPCIVPDResourceCustomCompareIndex() function we
have two variables @a and @b, both marked as g_autoptr(). Then,
towards the end of the function b->value is freed and set to
a->value. This is to make sure
virPCIVPDResourceCustomCompareIndex() works correctly even if
->value member is the same for both arguments.
Nevertheless, if the function returns anything else than 0 then
the control executes subsequent return statement and since
b->value points to the very same string as a->value a double free
will occur. Avoid this by setting b->value to NULL explicitly,
just like we are already doing for the successful path.

The idea behind virNWFilterBindingObjNew() is to create and
return an object of virNWFilterBindingObjClass class. The class
is virObjectLockable (and the corresponding
_virNWFilterBindingObj structure has virObjectLockable parent).
But for some reason plain virObjectNew() is called. This is wrong
because the mutex in the parent is left uninitialized.
Next, the returned object is not locked. This is wrong because in
some cases the returned object is added onto a list of bindings
and then passed to virNWFilterBindingObjEndAPI() which unlocks it
right away. This is potentially dangerous because we might just
have unlocked the object for another thread.
