Rename QubesDaemonNoResponseError to more intuitive
QubesDaemonAccessError (keep legacy name still working).
Use QubesPropertyAccessError whenever the access is about @property -
this makes it easy to use `getattr` to use default value instead.

Add "paranoid restore" mode
rpm/deb: add dependency on scrypt
utils: add simple locking primitive
backup/restore: use qfile-unpacker in a VM, request disk space monitoring
backup/restore: option for alternative qrexec service
backup/restore: improve error message about restoring tags
backup/restore: distinguish dom0 by name
Xterm doesn't preserve exit code of the process running inside. This
means, the whole xterm always exits with 0, even if qvm-backup-restore
failed.
Fix this by printing the exit code at the end to the log and then extract
that last line from the log on the calling side. This way we can also
distinguish whether qvm-backup-restore or xterm failed.
Allow running unattended, with qvm-backup-restore --passphrase-file.
This require few modifications:
- copy the passphrase file into the DisposableVM (that VM knows the
passphrase anyway, so there is no extra data leak)
- close the terminal when operation finishes
Closing the terminal would eliminate almost all the feedback (operation
log, errors, warnings etc), so write it into a file in DisposableVM and
later extract it and show on the stdout. Similar to qvm-run, color it
red as a content coming from a VM.

Having Admin API, it is possible to do this properly now:
- create DisposableVM
- assign it proper permissions to create VMs and control those created
VMs
- run restore process inside
- cleanup DisposableVM afterwards
Since the RestoreInDisposableVM class contains de facto reverse parser
for qvm-backup-restore command line, add a test that will spot when it
gets out of sync.
This feature depends on modifications in various other components,
including:
- linux-utils and core-agent-linux for update qfile-unpacker
- core-admin for qrexec policy modification
QubesOS/qubes-issues#5310
Standard python locking modules do not provide detection if lock-holding
process is still alive. Add a simple wrapper around fcntl.lockf that do
just that.
Make it possible to use qvm-backup-restore in a VM. This commit is about
accessing backup itself, when stored in another VM. This involve using
qfile-unpacker instead of qfile-dom0-unpacker and also requesting disk
space monitoring, as a VM probably won't have enough space to hold the
whole backup at once.
