Add convenient collection wrapper for easier getting selected volume.
Storage pool implementation may still provide only volume listing
function (pool.list_volumes), or, additionally, optimized
pool.get_volume.
This means it is both possible to iterate over volumes:
```python
for volume in pool.volumes:
...
```
And get a single volume:
```python
volume = pool.volumes[vid]
```

meminfo (written by VM) is expected report KiB, but qmemman internally
use bytes. Convert units.
And also move obscure unit conversion in is_meminfo_suspicious to more
logical place in sanitize_and_parse_meminfo.
Check if exit code retrieved from dom0 is really the one expected.
Fix typo in test_065_qrexec_exit_code_vm (testvm1/testvm2), adjust for
reporing remote exit code and remove expectedFailure.
QubesOS/qubes-issues#2861
Since tests expose qubesd socket, qvm-start-gui should handle starting
GUI daemons (so, GUI session inside VM). Add synchronization with it
using qubes.WaitForSession service.
When test expect to wait for remote process, use vm.run_for_stdio.
Additionally, when the call fail, (stdout, stderr) is not assigned - use
the one attached to exception object instead.
Since run_for_stdio raise an exception for non-zero exit code, it isn't
ignored anymore. So, check if qrexec-client-vm return expected value,
instead of keep ignoring it.

Test suite creates some VMs and needs to pass the knowledge about them
to qrexec policy checker. This is done using Admin API, so we need to
substitute qubesd with our own API server.
register_event_handlers is called early, when libvirt connection may not
be yet established - especially on empty qubes.xml. Do not skip
automatic connection logic.
* qubesos/pr/111:
vm: drop 'internal' property
qmemman: make sure to release lock
qmemman: fix meminfo parsing for python 3
devices: drop 'data' and 'frontend_domain' fields, rename 'devclass' to 'bus'
* qubesos/pr/110:
storage: use direct object references, not only identifiers
vm: fix volume_config
storage/lvm: prefix VM LVM volumes with 'vm-'
storage: fix VM rename
Make qubes.NotifyTools reuse logic of qubes.FeaturesRequest, then move
actual request processing to 'features-request' event handler. At the
same time implement handling 'qrexec' and 'gui' features request -
allowing to set template features when wasn't already there.
Behavior change: template is no longer allowed to change feature value
(regardless of being True or False). This means the user will always be
able to override what template have set.
