Updated according to ShaderEffectItem -> ShaderEffect API changes.

Avoid killing clients with sigpipe when transfering clipboard data.

When transfering selection data from sender to receiver, normally they
both block on the write and read. However blocking on the read when
retaining the data is sub-optimal for the compositor. Therefore it
uses non-blocking I/O (*) but this seems to introduce a chance of
having the clients terminating with SIGPIPE signal due to trying to
write when the compositor has already closed the handle and started to
retain another selection from another client. (all this caused by a
rapid succession of QClipboard::setMimeData calls)

The patch ensures that the read end of the pipe is not closed until
all data has been read, even if a newer selection gets activated
meanwhile, in which case the data (that became obsolete) is simply
ignored.

(*) The patch also enables real non-blocking I/O which was missing
for some reason, until now the compositor blocked when the first
reaady to read signal came.

Support QImage and others in Wayland clipboard.

The wayland plugin's clipboard implementation lacked support for data
set via QMimeData::setImageData, QClipboard::setPixmap, etc. because
everything was treated as a QByteArray. A variant having an image
cannot however be converted to a byte array. Therefore, to make these
convenience functions to work, the image is now encoded via
QImageWriter before sending it. On the receiving side QMimeData is
capable of decoding images from byte arrays, so no problem there.
The patch also renames an internal QWaylandMimeData class to a more
suitable clipboard-specific name as the functionality is clipboard
specific.

The XCB plugin has experimental support for connecting to multiple X
displays simultaneously, creating one or more QScreen for each.

Add drag'n'drop and basic cursor support.

and now: the (hopefully) correct fix

in fact, that private header comes from qtdeclarative

fix build

the usage of declarative makes our code use opengl-private even without
opengl itself being used.

recognize QT_WAYLAND_GL_CONFIG also as a qmake variable

unlike an environment variable set only for the time being, this
actually survives automated rebuilds of makefiles

clean up the QT+= stuff in the project files

so that we don't have to inject privates from the outside.
after recent cleanups, only qtcore and qtopengl privates are necessary,
and that only in the compositor api.

Reduced usage of private headers

Integration of v8 lead to a lot of v8 headers being included from
private QtDeclarative headers. As v8 headers are not installed, this
broke the compositor build. This change reduces the usage of private
headers to the minimum.
