Fixed qml-compositor failing on XComposite EGL / GLX.

We also need to make sure that the QWindow has actually been created at
this point, before creating a child window to be used as the fake root
for composited windows.

Don't call glDeleteTextures() when texture_id is 0.

Fixed XComposite hardware integration.

The root window needs to actually be mapped in order for
XCompositeNameWindowPixmap to work.

Also make sure to set both the window and pixmap bits in case we're on a
stricter EGL / GLX implementation.

Disabled DESTDIR for the wayland platform

This enables make install to work correctly.  This should be fixed when
this is moved into the QtWayland module.

Build fix

Cleaned up project files

Removed references to Widgets module that is not needed anymore.  Also
make qml-compositor deployable with make install.

Get rid of the textureChanged signal.

We trigger update directly from damage now, so we don't need this signal anymore.

Make sure we always release buffers

If for some reason the compositor is not able to handle a buffer
before the next one arrives, the buffer would be locked forever.
This change detects that case, and adds an "emergency release", and
displays a warning.

Make sure we update the item when the buffer is damaged.

Done with Samuel.
