- Add Ncurses patch 20170708
  + add a note to tic manual page about -W versus -f options.
  + correct a limit-check in fixes from 20170701 (report by Sven Joachim). 
- This also for bug bsc#1047964 and bug bsc#1047965

- Add ncurses patch 20170701 (bsc#1046853, bsc#1046858)
  + modify update_getenv() in db_iterator.c to ensure that environment
    variables which are not initially set will be checked later if an
    application happens to set them (patch by Guillaume Maudoux).
  + remove initialization-check for calling napms() in the term-driver
    configuration; none is needed.
  + add help-screen to test/test_getstr.c and test/test_get_wstr.c
  + improve compatibility between different configurations of new_prescr,
    fixing a case with threaded code and term-driver where c++/demo did
    not work (cf: 20160213).
  + the fixes for Redhat #1464685 obscured a problem subsequently
    reported in Redhat #1464687; the given test-case was no longer
    reproducible.  Testing without the fixes for the earlier reports
    showed a problem with buffer overflow in dump_entry.c, which is
    addressed by reducing the use of a fixed-size buffer.
  + add/improve checks in tic's parser to address invalid input
    (Redhat #1464684, #1464685, #1464686, #1464691).
    + alloc_entry.c, add a check for a null-pointer.
    + parse_entry.c, add several checks for valid pointers as well as
      one check to ensure that a single character on a line is not
      treated as the 2-character termcap short-name.
  + fix a memory leak in delscreen() (report by Bai Junq).
  + improve tracemunch, showing thread identifiers as names.
  + fix a use-after-free in NCursesMenu::~NCursesMenu()
  + further amend incorrect calls for memory-leaks from 20170617 changes
