Install files in /etc/qubes-rpc for all methods defined in API
documentation, even if not yet implemented (qubesd will handle it
raising appropriate exception).
Use minimal program written in C (qubesd-query-fast), instead of
qubesd-query in python for performance reasons:
- a single qubesd-query run: ~300ms
- equivalent in shell (echo | nc -U): ~40ms
- qubesd-query-fast: ~20ms
Many tools makes multiple API calls, so performance here do matter. For
example qvm-ls (from VM) currently takes about 60s on a system with 24
VMs.
Also make use of `$include:` directive in policy file, to make it easier
defining a VM with full Admin API access.
QubesOS/qubes-issues#853
Use '<option name="option_name">option_value</option>' instead of
'<options option_name="option_value"/>'. It's more consistent with the
rest of qubes.xml - have one thing per element.
Also, add options deserialization test.
When libvirt domain is not defined, it isn't running for sure.
This commit fixes the case when vm.is_running() appears anywhere in the
code used during libvirt xml building. In this case, it's mostly about
PCI device description for libvirt.
Make it easy to retrieve DeviceInfo object out of DeviceAssignment
object. The only missing piece of information for that is device class,
so add it. Make it optional, as it can be filled on demand when passing
the object through DeviceCollection (either by listing devices, or
attaching/detaching).
This is mostly to ease handling options in libvirt template - to get
them, you need to use `assignments()`, istead of `persistent()` or
`attached()`, but there were no _simple_ way of getting actual device
object.
This also makes DeviceCollection._device method not needed anymore.
Filter in python3 returns a generator, can be iterated only once.
This is about list of existing domains - store it as a list, otherwise
domains will "disappear" after being discovered.
qubesd do start other daemons - make sure they will not try to signal
systemd about it. In some cases such daemons (qubesdb-daemon) behave
differently based on this variable.
Do not initialize it only at qubes.xml load time, but re-read vm.kernel
property each time the path is constructed. While at it, add support for
vm.kernel set to 'None' - simply don't include modules.img (xvdd) then.
This service currently does more harm (desync libvirt state with
reality) than good. Since we have qubesd, we may come back to
implementing it properly using libvirt events.
When device extension do not return some "persistent" device as
currently attached, still return it, as it will be attached at next
domain startup. User can distinguish such devices by having
frontend_domain=None (or other VM).
Also, return a set from DeviceCollection.assignments().
While at it, adjust implementation to specification: tags don't have
value, only one bit of information (present/not present).

It doesn't really make sense to keep man pages in separate package.
Previously it was done to avoid some build dependencies (pandoc require
a lot of them), but it isn't a problem anymore.
