For all supported QEMU version, the virt machine type has a hard

The XML parser for consoles sets the 'port=' attribute of '<target' to
be always the index of the console.
Thus when the "really crazy backcompat stuff for consoles" function
modifies the order of consoles by inserting the default one for a serial

change on subsequent parse.
This luckily didn't cause any visible changes to the VM as the port

The 'size' of a 'shmem' device is parsed and formatted as a "scaled"
value, stored in bytes, but the formatting scale is mebibytes. This
precission loss combined with the fact that the value was validated only
when starting and the size is formatted only when non-zero meant that
on first parse a value < 1 MiB would be accepted, but would be formatted
to the XML as 0 MiB as it was non-zero but truncated and a subsequent
parse would parse of such XML would parse it as 0 bytes, which in turn
would be interpreted as 'default' size.
Fix the issue by moving the validator, which ensures that the number is
a power of two and more than 1 MiB to the validator code so that it'll
be rejected at XML parsing time.

Similarly to auto-adding of controllers, the assignment of indexes can
cause them to be considered in different ordering according to the logic
in 'virDomainControllerInsert' than they currently are.
To prevent changes in commandline between first run after defining a VM
xml and any subsequent run or restart of the daemon, we need to reorder
them when assigning the index.
The simplest method is to assign indexes and then create a new list of
controllers and re-instert them.

'virDomainDefAddController' which is used in code-paths which auto-add
controllers to the definition such as 'virDomainDefMaybeAddController',
'virDomainDefAddUSBController', 'qemuDomainDefAddDefaultDevices' was
adding the controller at the end of the list. However that is not how
the XML parser would order the controller in the list as it uses
virDomainControllerInsert grouping them by type and additional
properties.
This would cause that auto-added controllers would re-order:
- between first and any subsequent run of the VM (even on commandline)
- after a libvirtd/virtqemud restart
- after any update of the definition based on the 'define' operation
(e.g. virsh edit)

of the 4 possibilities:
By invocation:

inactive -> inactive;
by unintentionally:
active -> inactive (for configs which don't set an 'id' as the
formatter assumes it's inactive)
To do it better introduce proper active -> inactive/active testing into
qemuxmlactivetest. It's chosen such as we only really parse an XML as
live when restoring a status XML. To give users possibility to avoid
constructing a full status XML add a simpler variant. As of such it will
be used only for configs where we specifically cared about parsing live
data.
To ensure that the formatter doesn't decide that a config is inactive
because it doesn't have an ID we fill in a domain ID if it was not
present in the source.
