Moved m_visual* wxApp[X11] members used by wxBitmap and

wxColour into a new wxXVisualInfo structure, and moved code
to initialize it to a new src/x11/utilsx.cpp file (utility
functions shared by wxMotif and wxX11).
  Added (currently unused) code in wxMotif to
retrieve wxXVisualInfo; it will be used when wxMotif
is switched to bitmap.cpp from wxX11.
