Add configure option to minimize xcb runtime dependencies

Some of the xcb- libraries we depend upon are not (yet) common across
distributions. This is problematic for binaries that should be working
on different distributions. The patch mitigates this by:

Adding the files from
  libxcb-proto (version 0.1.6), compiled with libxcb-1.5
  xcb-util (version 0.3.9)
  xcb-util-image (version 0.3.9)
  xcb-util-keysyms (version 0.3.9)
  xcb-util-renderutil (version 0.3.8)
  xcb-util-wm (version 0.3.9)

from xcb.freedesktop.org/dist to src/3rdparty/xcb.

Adding a configure option '-qt-xcb' to use the sources instead of
linking to the respective runtime libraries.
