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)

Instead of calling 'su' to switch the user, use own implementation of
this. Thanks to PAM it's pretty simple. The main reason is to have
control over process waiting for session termination (to call
pam_close_sesion/pam_end). Especially we don't want it to keep std* fds
open, which would prevent qrexec-agent from receiving EOF when one of
them will be closed.
Also, this will preserve QREXEC_AGENT_PID environment variable.

It isn't really needed. It was used to workaround libusb bug (causing
crash when the system does not have any USB controller), but since we
use HVM now which do have some USB controllers it isn't needed anymore.
Also, it is not available in stock Fedora kernels.
Qubes VM require few config options in grub. Ship appropriate
configuration. Debian have grub.d support, so it can be done cleanly.
On Fedora, /etc/default/grub needs to be modified. Still keep the
options in separate file, but include it manually from
/etc/default/grub.

- there are many netcat versions (openbsd, nmap, ...), which behave
differently - especially while handling EOF
- Debian jessie doesn't have nmap-ncat (which handle EOFs sufficiently
good)

While it doesn't make sense to install qubes-core-agent without qrexec,
it may make sense to do the otherway around - install just
qrexec-agent without all the qrexec services and configuration. For
example on some pre-installed system.

When a file is moved to other package, the new package needs Replaces:
and Breaks: dependecies on old package. Otherwise dpkg will refuse to
change file ownership.

This will save a lot of dependencies if networking is not needed in VMs
based on given template. Thanks to updates proxy over qrexec, template
itself do not need to have network configured too.

In Fedora it makes little sense, but in Debian it allows to avoid a lot
of dependencies. So split in both, to keep it simple.

This is meant to notify dom0 about features supported by just-installed
template. This service is called by dom0 just after template
installation.

Configure package manager to use 127.0.0.1:8082 as proxy instead of
"magic" IP intercepted later. The listen on this port and whenever
new connection arrives, spawn qubes.UpdatesProxy service call (to
default target domain - subject to configuration in dom0) and connect
its stdin/out to the local TCP connection. This part use systemd.socket
unit in case of systemd, and ncat --exec otherwise.
On the other end - in target domain - simply pass stdin/out to updates
proxy (tinyproxy) running locally.
It's important to _not_ configure the same VM to both be updates proxy and
use it. In practice such configuration makes little sense - if VM can
access network (which is required to run updates proxy), package manager
can use it directly. Even if this network access is through some
VPN/Tor. If a single VM would be configured as both proxy provider and
proxy user, connection would loop back to itself. Because of this, proxy
connection redirection (to qrexec service) is disabled when the same VM
also run updates proxy.

...but installed on all Debian versions. This is mostly required by
vebose file list in debian/qubes-core-agent.install. But also make it
use new options when upstream will set them.

This reverts commit 5dfcf06ef4.
python3-daemon isn't widespread enough yet - for Debian jessie available
only in packports.
In addition to the revert itself, adjust packaging for this change
(mostly for Debian).
Add --install-layout=deb option to setup.py, so files will not land in
/usr/local.
Also, explicitly list packaged files - make it easier to split the
package later.
This way:
- VM prompt do know VM list, the list may be filtered based on policy
- source VM don't learn name of target VM
