Print some error even without --pass-io, otherwise the only way to learn
the failure is checking $?, as no other visual sign is there.

qubes.VMShell service, used by qvm-run, expects the command on the first
input line. Previously, when --localcmd was used, the command wasn't
written anywhere and the local command was connected directly to
qubes.VMShell service. And the first line of its output was interpreted
as a command.
Fix this by starting the local command separately, after sending the
command to qubes.VMShell service.
While at it, unify handling shell command and service calls in the process.
vm.run_service(..., localcmd= ) isn't that useful in general case,
because for qubes.VMShell the caller first need to send the command
before starting local process. Since the qvm-run tool needs to implement
manual starting localcmd anyway, don't use localcmd= run_service's
argument at all to unify calling methods.
There is slight behavior change: previously localcmd was started only
after establishing service connection (for example only if qrexec policy
allows), now it is started in all the cases.

By definition StandaloneVM is not linked to the template. Creating one
from a template is a clone operation. It's already possible using
qvm-clone tool, but it's logical to do that using qvm-create tool too.
This was the case in R3.2 too.
While adding this special case, skip cloning private volume, to preserve
behaviour of TemplateBaseVMs which do not inherit private volume either.
FixesQubesOS/qubes-issues#3793
If file to be imported is larger than the default root volume, resize
the volume first. It might be also a good idea to shrink it when needed,
but currently the backend refuse it.

* windows-tools:
doc: add info what properties are inherited from template
Add 'gui-emulated' feature
qvm-start-gui: fix handlign rpc-clipboard feature
Add an explicit method for forcing emulated VGA output. Previously it
was possible only by removing `gui` feature (setting it to false had a
different effect), or enabling debug mode.
Using lack of a feature as a third state was a bad idea.

Do not crash if qubesd restart exactly the moment event handler was
called.
Event listener properly handle qubesd restarts (reconnects), but exists
if any handler raise an exception. Avoid this by logging such exceptions
but not propagating them.
There was such option on Qubes 3.2, so add it here too. This is
especially useful for kernel package - preun script use it to verify if
given kernel isn't needed anymore.
* improved-tools-messages:
tools: suppress full traceback in console tools
tools: add SubParsersHelpAction, which include subcommands details in --help
Right now Admin API backend will refuse to shrink volume anyway, but
we're planning to relax this restriction. Make sure the client side
(qvm-volume tool here, GUI VM settings already have this in place) will
employ appropriate safety check.

If needs to be extended - do it before import. If needs to be reduced -
after. This way, if data import fails for any reason, previous data
won't be destroyed (truncated).
Also, convert error on shrinking volume to a warning, as it doesn't break
the template (just leave it with bigger disk than needed). Currently all
storage pool implementations refuse to shrink a volume (but it may
change in the future).
QubesOS/qubes-issues#3169
QubesException class is used with meaningful messages and should be ok
to use it directly as error message. For other exceptions, still use
full traceback (most likely a bug somewhere, not user error).
FixesQubesOS/qubes-issues#3610
Don't print None value as 'None' string, but as empty one (same as at
API level). Otherwise it is indistinguishable from VM named 'None', or
same string property value.
This is especially important on LVM thin pool, where space after
removing the file needs to be given back to the pool, to be reused for
other volumes (for example this template).
qvm-start-gui lifecycle should be bound to X server lifecycle. It should
be restarted when user logoff and login again, at least to start
gui-daemons again.
Do that by opening a connection to X server and reacting to breaking
that socket.

I don't know if any template currently hits this code path, even the
fedora-26-minimal root.img is large enough to be split into multiple
parts. Maybe Arch Linux?

'qvm-run --dispvm' cannot easily make a separate qubes.WaitForSession
call. Instead, if --gui is active, pass the new WaitForSession argument
to qubes.VMShell, which will do the equivalent.
The unit tests have been copied (in slightly adapted form) from commit

In core-admin matching collections are real dicts, so clone this API
behaviour here too. Specific changes:
- iteration yields keys, not values
- implement values and items methods
Additionally fix keys method, it was broken on python2 (list have no
copy method).
It wasn't possible to use QubesArgumentParser(vmname_nargs=...) for
optional domain list - the option forced usage of either --all or
explicit domain list.
When starting a VM with --cdrom=some-vm:/some/path/to.iso, it can be
started only when loop device matching the path is available. For now,
add naive waiting (while ... sleep(1)) for it. Later it might worth
converting it to events handling.
* qubesos/pr/44:
Fix style else-return
tests: update qvm-template-process and qvm-remove tests
Add --force to manpage.
Avoid cloning installed_by_rpm
Print vm list before prompt
Use --force instead of --yes
Toggle installed_by_rpm in template tool
Fix error message grammar
Add --yes option and confirm prompt.
The main process sometimes sets fd 1 to O_NONBLOCK, and since in the
terminal case fd 0 and 1 are the same fd, this also results in fd 0
being non-blocking, causing qvm-run to crash with EAGAIN.
So just make the code work for both blocking and non-blocking stdin.
When some VM timeout on shutdown, the tool will try to kill all of them,
but at this point some of them may be already powered off (not all
hanged during shutdown, but only some). Handle this
situation instead of crashing. And add appropriate test.
1. Output of `losetup` command contains `\n` - strip it.
2. Provide read-only option - if device info hasn't propagated to qubesd
yet, it will not be set automatically.

Very few calls at client side really needs VM class name. So, even in
non-blind mode use just QubesVM class, to avoid strange cases depending
on blind mode being enabled or not. Then, have VM class name in 'klass'
property. If known at object creation time, cache it, otherwise query
qubesd at first access.
Booting a VM from cdrom require attaching the device before VM startup,
which is possible only in persistent mode. But for qvm-start --cdrom
adding a cdrom only temporarily, use new update_persistence() function
to convert the assignment to temporary one.
