This qrexec is meant for services, which require some kind of
"registering" before use. After registering, the backend should invoke
this call with frontend as the intended destination, with the actual
service in argument of this call and the argument as the payload.
By default this qrexec is disabled by policy.

Add auto_cleanup property, which remove DispVM after its shutdown
- this is to unify DispVM handling - less places needing special
handling after DispVM shutdown.
New DispVM inherit all settings from respective AppVM. Move this from
classmethod `DispVM.from_appvm()`, to DispVM constructor. This unify
creating new DispVM with any other VM class.
Notable exception are attached devices - because only one running VM can
have a device attached, this would prevent second DispVM started from
the same AppVM. If one need DispVM with some device attached, one can
create DispVM with auto_cleanup=False. Such DispVM will still not have
persistent storage (as any other DispVM).
Tests included.

* services:
tests: check clockvm-related handlers
doc: include list of extensions
qubesvm: fix docstring
ext/services: move exporting 'service.*' features to extensions
app: update handling features/service os ClockVM
Since qubesd properly handle chained startup of sys-net->sys-firewall
etc, we don't need a separate service to start netvm explicitly earlier.

clock synchronization mechanism rewritten to use systemd-timesync instead of NtpDate; at the moment, requires:
- modifying /etc/qubes-rpc/policy/qubes.GetDate to redirect GetDate to designated clockvm
- enabling clocksync service in clockvm ( qvm-features clockvm-name service/clocksync true )
Works as specified in issue listed below, except for:
- each VM synces with clockvm after boot and every 6h
- clockvm synces time with the Internet using systemd-timesync
- dom0 synces itself with clockvm every 1h (using cron)

This ease Admin API administration, and also adds checking if qrexec
policy + scripts matches actual Admin API methods implementation.
The idea is to classify every Admin API method as either local
read-only, local read-write, global read-only or global read-write.
Where local/global means affecting a single VM, or the whole system.
See QubesOS/qubes-issues#2871 for details.

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.
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.

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.
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.
This all either have been migrated to core3, or is not needed anymore.
There is still qvm-tools directory with a few tools that needs to be
migrated, or installed as is.
qvm-ls tool (as all other tools) will be accessing properties through
API, so no need (nor sense) for this tool-specific attributes in
qubes.property. The only somehow used was ls_width, and in fact it made
the output unnecessary wide.
The tool itself is already moved to core-mgmt-client repository.
QubesOS/qubes-issues#853
This way it will work independently from where qrexec-policy tool will
be called (in most cases - from a system service, as root).
This is also very similar architecture to what we'll need when moving to
GUI domain - there GUI part will also be separated from policy
evaluation logic.
