The test put a reference to the XCB::Window as data
to the _net_wm_transient property, not the window ID
This "works" (you get various garbage transients for
the leader in addition) as long as the window id itself
is the first item in the structure (because that is what
the test resolves to verify what it has done) bug fails
when the XCB::Window structure changes and anything
is the first item (or, btw., when the compiler feels
to re-align the structure and adds some padding...)
So let's fix the test by at least passing the proper
data reference.

KWin::connection() uses the property to resolve the value instead of
using QX11Info. In practice this doesn't change anything at the moment,
but allows kwin_wayland to provide an xcb connection without depending
on QX11Info.
As we cannot make xcb_connection_t* available as a metatype, the
property's type is set to void*.
KWin::rootWindow() uses the property to resolve the value instead of
using QX11Info. In practice this doesn't change anything at the moment,
but allows kwin_wayland to provide a root window without depending on
QX11Info.
A wrapper class for MotifHints is added to xcbutils. This class manages
the information about the read Motif hints, so that Client doesn't need
to have a copy of the read states.
The class is designed in a way that during Client::manage we get rid of
another roundtrip.

This restores the behavior on KWin4: if I set an X property that doesn't have any data on a window, it's still information, so this makes the Xcb wrapper return an empty QByteArray that is not null.
EffectWindow::readProperty() now returns an empty QByteArray constructed the same way as it was in KWin4.

The Xcb::Property can wrap the xcb_get_property call and provides
convenient access methods to read the value of the reply with checks
applied. For this it provides a templated ::value method for reading a
single value or reading an array. There's also a ::toBool and
::toByteArray which performs the conversion directly with default values
for the type and format checks.
Xcb::TransientFor is changed to be derived from Property instead of
Wrapper directly, so that the reading of the property value can be
shared.
Xcb::StringProperty is a convenient wrapper derived from Property to
handle the reading of a string property providing a cast to QByteArray
operator. This replaces the ::getStringProperty from utils. Though the
separator functionality from ::getStringProperty is not provided as that
is only used in one function and handled there.
All the custom usages of xcb_get_property or getStringProperty are
replaced to use this new wrapper. That simplifies the code and ensures
that all properties are read in the same way.
