Qubes manager used different logic what it considers as "running VM",
than qubes core.
Here it was "running or starting/stopping", while qubes core uses the
same as libvirt (isActive()), which effectively means "not halted" -
which includes also "paused" and "suspended". This creates a lot
confusion in which action should be available when.
The actual detected bug was about resuming paused VM. There was assert
"not vm.is_running()", while the paused VM _is_ running in terms of
qubes core.

QubesVmCollection is not thread safe. If for example update_table() will
be called during some long-running task (like creating or removing VM),
it will try to reload qubes.xml (so get read lock first), but the thread
already holds a lock on this file. This would result in "Lock already
taken" exception.

QubesVm object caches some domain state (domain ID in libvirt object,
Qubes DB connection socket), which can become out of date in
case of start/stop events. Currently it needs manual trigger to refresh
itself.
This reverts commit 227597cf93.
QubesWatch no longer supports xenstore, so there is no simple way to
get this column updated. This is conscious decision in process of making
R3 Xen-independent.

In Fedora 20 sudo cannot be called from qrexec call (no tty available),
so run it in separate call as root.
Also add "-P" option to qubes-update-check call: for SysV systems it
should be ignored and service started as normal user (which is just
fine), but on systemd systems, the call would be redirected to
systemctl, which refuse normal user service actions. "-P" flag acquires
root privileges using PolicyKit.
Window size is fixed (calculated based on VMs count etc) so it isn't
useful. Without correctly calculated base size hint it can cause wrong
manager window size. It actually happens on fc20 in dom0.
Apparently KDE parses HTML tags in tray notifications only when some of
them appears on the first line of the message. So add some there.
This doesn't affect Xfce, which always parses HTML tags.
When the file doesn't exists, adding a watch fails. So monitor directory
for IN_CREATE event and when file is created - add the modify watch.
This watch will miss the first update (rather: create), so fire it
in IN_CREATE handler.
