Summary:
We don't remotely support multihead in plasmashell.
Nor do we support two plasmashells running to fake it.
SDDM doesn't either.
Kwin has some code, but we don't check the screen before
choosing the DBus service to use. I doubt it works well.
This kills some code, and a blocking call to klauncher.
(Note, multihead has nothing to do with xrandr spanning screens)
Test Plan:
Code grep
Compiles

Summary:
The current code registers the session bus *after* app->exec() this
effectively means it won't work.
This causes ksmserver to be unable to deliver the calls to start kcminit
modules at remaining init phases.
Any KCMinit module which are at X-KDE-Init-Phase=1 or 2 will now get
run. It also means kcminit_startup closes, instead of lingersing on
startup doing nothing until it times out 5 minutes later.
Test Plan: Confirmed kcminit_startup now exits properly.

Summary:
KCMInit is loaded early in startkde, and it blocks all other processes
from starting until it is complete.
This can be up to 1.1 seconds.
(http://imgh.us/bootchart-20160928-1316.svg)
A sizable amount of time (46% of CPU) is spent loading our QPT. This
isn't very useful given none of the kcm_init scripts have any UI and
it's not something they should have. It's only a QGuiApplication so that
they have an X connection.
Test Plan: Checked it ran without errors

this returns us to behaviour of kde4 times (e.g. this is what kwin expects).
each x11 screen in xcb terminology is a virtual desktop,
potentially a collection of separate juxtaposed monitors.
while QScreen is representing only one output (e.g. DVI-I-1, VGA-1, etc.)
which may be combined with others into one virtual desktop.
see QXcbConnection::updateScreens()

this reduces number of libraries to link with from over 100 to 50
and improves base binary run time on my lenovo e330 from 8 seconds to less than 6
(and hence improves system startup time, yay!)
Martin: i will do a switch from QGuiApplication::screens() to xcb screens
separately because it changes behaviour comparing to kde4

registerService() isn't sufficient, this has probably been broken
since the port from DCOP. The exported object is used by ksmserver
to talk to kcminit during startup
