Implemented DoGetBestSize for wxListBox, (native) wxComboBox and

wxTextCtrl, and used it when wxSize(-1, -1) is passed to Create, to set
the initial size.
  Added wxDoChangeFont and wxXmStringToString helper functions, removed
the use of m_stringList in native wxComboBox, removed some duplicated code
in wxWindow.
