ncurses 5.9 - patch 20141011

+ add experimental support for xterm's 1005 mouse mode, to use in a
  demonstration of its limitations.
+ add experimental support for "%u" format to terminfo.
+ modify test/ncurses.c to also show position reports in 'a' test.
+ minor formatting fixes to _nc_trace_mmask_t, make this function
  exported to help with debugging mouse changes.
+ improve behavior of wheel-mice for xterm protocol, noting that there
  are only button-presses for buttons "4" and "5", so there is no need
  to wait to combine events into double-clicks (report/analysis by
  Greg Field).
+ provide examples xterm-1005 and xterm-1006 terminfo entries -TD
+ implement decoder for xterm SGR 1006 mouse mode.
