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.

The qubesd daemon have no information about clone source - from that
side it looks like a new VM. This means application menu is created as
for a new VM.
To fix this re-initialize menu with --source option as part of the clone
operation. It will copy both list of available applications (if
applicable) and selected applications.
This fixes both qvm-clone case and rename.

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.
FixesQubesOS/qubes-issues#3422
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.
QubesOS/qubes-issues#3585
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.
QubesOS/qubes-issues#3725
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).

'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

When calling a service in DispVM, the connection is established only
after session is ready (if required for given service). qrexec-client by
default use 5s here, which is too low depending on hardware. Use
'qrexec_timeout' property here for DispVM case.

* 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.
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.

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.
FixesQubesOS/qubes-issues#3055
Add option to uniformly start new DispVM from either VM or Dom0. This
use DispVMWrapper, which translate it to either qrexec call to $dispvm,
or (in dom0) to appropriate Admin API call to create fresh DispVM
first.
This require abandoning registering --all and --exclude by
QubesArgumentParser, because we need to add --dispvm mutually exclusive
with those two. But actually handling those two options is still done by
QubesArgumentParser.
This also updates man page and tests.

New qvm-backup tool can either use pre-existing backup profile
(--profile), or - when running in dom0 - can create new one based on
used options (--save-profile).
This commit add a tool itself, update its man page, and add tests for
it.

* devel-2-qvm-run-1:
Make pylint happy
tools/qvm-run: fix handling EOF
tests: mark qvm-run tests with "expected failure"
tools/qvm-run: fix handling copying stdin to the process
since qvm-run use multiprocessing.Process now, stdin sent to it is
processed in separate process and doesn't come back to
TestApp.actual_calls (self.app). Annotate tests for now, to be fixed
later.
Do not close event loop in utility function - handle it only in main().
For this reason, change appropriate functions to coroutines.
FixesQubesOS/qubes-issues#2865
Don't start GUI daemon for given VM twice when qvm-start-gui was started
during VM startup (while waiting for qrexec startup). This is especially
common while running tests.
Report failed qubes.SetMonitorLayout as warning (instead of unhandled
exception).
Clear VM cache on qubesd reconnect.
Fix logging.
This way we don't need separate admin.vm.Clone call, which is tricky to
handler properly with policy.
A VM may not have access to all the properties and other metadata, so
add ignore_errors argument, for best-effort approach (copy what is
possible). In any case, failure of cloning VM data fails the whole
operation.
When operation fails, VM is removed.
While at it, allow to specify alternative VM class - this allows
morphing one VM into another (for example AppVM -> StandaloneVM).
Adjust qvm-clone tool and tests accordingly.
QubesOS/qubes-issues#2622
Enable 'qrexec' VM feature to wait for qrexec initialization - it is
required to call qubes.PostInstall service. If VM start fails, assume
there is no qrexec and drop that feature.
Since we use qubes.VMShell service now and send requested command on its
stdin, we need to terminate that shell after requested command -
otherwise the service will not terminate automatically waiting for
further input (next commands).
qubesd_call expect "bytes" type. Additionally serialize false value as
empty string (which is treated by python as false value), because
otherwise would be serialized to (non-empty) string, which is true value
in python.
