0032323: Configuration - drop unused dependency from Xmu

Removed unused header Aspect_XWD.hxx.
Removed redundant includes of unused X11 extension headers.
Added missing dependency on pthread to TKDraw.

Added "-z defs" linker flag to qmake projects to detect missing library dependencies.
Removed unused CSF_MotifLibs.
