Currently if the path isn't managed on a remote connection we
treat it as file. Add this simple heuristic to improve the common
case.

Generally this doesn't work with qemu metadata locking nowadays,
and it was never a safe idea to begin with, because disk contents
could be in an inconsistent state.

This reworks the existing code to never have storage_backend = None,
instead carrying around a stub class, and resolving the actual
storage info when necessary. This makes the logic easier to follow.

The way we set controller_model earlier, means all the virtio-scsi
allocation code is essentially never set. That code does still fix
a valid case of when trying to add a scsi device when there isn't
any remaining slots open, but that should be rare enough that I'm
fine telling the user to edit manually set up a controller themselves
first.

Taken from virt-manager code. Move it here because it is strictly
an XML operation, and it will be easier to unit test
Signed-off-by: Cole Robinson <crobinso@redhat.com>
Move the opencoded impl out of virt-manager details.py and into
virtinst, since this is entirely about XML comparison. Add tests for
it

This layout is closer to what most python modules have nowadays.
It also simplifies testing and static analysis setup.
Keep virt-* wrappers locally, for ease of running these commands
from a git checkout.
Adjust the wrapper binaries we install on via packaging to be
pure python, which makes things like running gdb easier.

For the dialog flow, these options are the same, the only effect
is that there's no longer an initial network boot phase.
PXE is dependent on an external server setup that is not common
in the scheme of things, so giving it a first class option on the
front of the new VM wizard isn't really sensible. Users that want
to PXE boot can easily do so via the 'customize before install'
option, or just manually create a VM and edit the boot device as
they see fit.
Explicitly advertising a Manual option is nicer for users that
just want to create a VM and deal with install later, among many
other minor use cases.

Add an info message that these can be set via the
'Customize before install' option. Duplicating this doesn't add a ton
of value here IMO

macvtap is problematic for inexperienced users so we shouldn't
be broadly advertising it, plus our device listing was incomplete
anyways.
Both bridge and macvtap device listing are largely dependent on
the libvirt virInterface APIs, which have varying degrees of
completeness across distros and are not particularly reliable to
begin with.
Drop both of these in favor of the available support for manually
specifying a device name
Signed-off-by: Cole Robinson <crobinso@redhat.com>
Similar to the bridge option. We will be removing the explicit
device listing support soon, so this will be required for specifying
a macvtap device

* macvtap is kinda problematic in general because it doesn't provide
out of the box host<->guest communication, and it requires a
special XML option just to get working ipv6. Users that know they
want it usually know this distinction, but if someone chooses it
without understanding the implications it can cause confusion.
This puts it hovering the intermediate/advanced user line which
makes me want to not advertise it as prominently as we currently do,
with an explicit list of host interfaces

Part of this is that the only source_mode that will work in a useful
