The "max" model can be treated the same way as "host" model in general.

The logic applied in the ppc64 case isn't quite correct, as the

is used or not. This is information the CPU driver doesn't have.

For hardware virtualization this is functionally identical to the
existing host-passthrough mode so the same caveats apply.
For emulated guest this exposes the maximum featureset supported by
the emulator. Note that despite being emulated this is not guaranteed
to be migration safe, especially if different emulator software versions
are used on each host.

The way we currently call completer callbacks is that if we've
found --option that user wants to complete value for and it has
callback set then the callback is called.
And just before that, if no --option to have the value completed
is found or is found and is of boolean type then a list of
--option is generated (for given command).
But these two conditions can never be true at the same time
because boolean type of --options do not accept values. Therefore
the calling of completer callback can be promoted onto the same
level as the --option list generation.
This means that merging of two lists can be dropped to and
completer callback can store its retval directly into @list (but
as shown earlier one of the string lists to merge is always
empty).

Completer callbacks generate all possible outputs ignoring any partial
input (e.g. prefix of a domain name) and then use vshCompleterFilter() to
filter out those strings which don't fit the partial input (prefix).
In contrast, vshReadlineCommandGenerator() does some internal filtering and
only generates completions that match a given prefix. Rather than treating
these scenarios differently, simply generate all possible options and
filter them all at the end.

The vshReadlineParse() function is called whenever user hits
<TAB><TAB>. If there is no command (or a partially written one),
then a list of possible commands is printed to the user. But, if
there is a command then its --options are generated. But
obviously, we can not generate --options if there already is an
--option that's expecting a value. For instance, consider:
virsh # start --domain <TAB><TAB>
In this case we want to call completer for --domain option, but
that's a different story.
Anyway, the way that we currently check whether --options list
should be generated is checking the type of the last --option. If
it isn't DATA, STRING, INT, or ARGV (all these expect a value),
then we can generate --option list. Well, writing the condition
this way is needlessly verbose and also prone to errors (see
d9a320bf97 for example).
We know that boolean type does not require a value. This leaves
us with the only type that was not mentioned yet - VSH_OT_ALIAS.
This is a special type for backwards compatibility and it refers
to another --option which can be just any type.

There are two functions that are used to generate completion
lists: vshReadlineCommandGenerator() for command names and
vshReadlineOptionsGenerator() for --options for given command.
Both return a string list, but may also fail while constructing

The aim of vshCompleterFilter() is to take a string list and a
prefix and remove all strings from the list that don't have the
desired prefix. The function is used to filter out those strings
returned by a completer callback that don't correspond with
user's (partial) input. For instance, domain name completer
virshDomainNameCompleter() returns all domain names and then
vshCompleterFilter() refines the list so that only domains with
correct prefix of their name are offered to user. This was a
design choice - it allows us to have shorter completers as they
do not have to copy the list filtering over and over.
Having said all of that, it may happen that a completer does not
return anything (e.g. there is no domain in requested state,
virsh is not connected and thus completer exited early, etc.). In
that case, the string list is NULL and vshCompleterFilter() can
simply return early.

We've invented VSH_OT_ALIAS type for --option so that we can
rewrite some --options (e.g. fix spelling). For instance
blkdeviotune command uses this feature heavily:
--options-with-dash are preferred over old
--options_with_underscore. Both versions are supported but only
the new ones (not aliased) are documented and reported in --help.
Except for options completer, which happily put also aliased
versions in front of user's eyes.
Note, there is a second (gross) way we use aliases: to rewrite
options from --oldoption to --newoption=value (for instance
--shareable option of attach-disk is an alias of
--mode=shareable). And just like with the previous group - don't
generate them into the list of possible options.

A few commits back I've introduced new 'virtio-pmem' <memory/>
device. Since it's virtio it goes onto PCI bus. Therefore, on
hotplug new PCI address is generated (or provided one is
reserved). However, if hotplug fails (for whatever reason) the
address needs to be released. This is different to 'dimm' type of
address because for that type we don't keep a map of used slots
rather generate one on each address assign request. The map is
then thrown away. But for PCI addresses we keep internal state
and thus has to keep it updated. Therefore, this new
qemuDomainReleaseMemoryDeviceSlot() function is NOP for those
models which use 'dimm' address type ('dimm' and 'nvdimm').
While I'm at it, let's release the address in case of hot unplug.
Not that is supported (any such attempt fails with the following
error:
"virtio based memory devices cannot be unplugged"
But if QEMU ever implements hot unplug then we don't have to
remember to fix our code.

However, making user find a non-occupied device name might be not
convenient, especially for the remote connections.
Update the logic to make these attributes optional. In case if not
specified, use /dev/nmdm$UUID[AB], where $UUID is a domain's UUID.
With this schema it's unlikely nmdm device will clash with other domains
