- 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
