ncurses 6.0 - patch
20170624
+ modify c++/etip.h.in to accommodate deprecation of throw() and
throws() in c++17 (prompted by patch by Romain Geissler).
+ remove some incorrect calls for memory-leaks from
20170617 changes
(report by Allen Hewes).
+ add test-programs for termattrs and term_attrs.
+ modify _nc_outc_wrapper to use the standard output if the screen was
not initialized, rather than returning an error.
+ improve checks for low-level terminfo functions when the terminal
has not been initialized (Redhat #
1345963).
+ modify make_hash to allow building with address-sanitizer,
assuming that --disable-leaks is configured.
+ amend changes for number_format() in
20170506 to avoid undefined
behavior when shifting (patch by Emanuele Giaquinta).
