+ + use "const" in some prototypes rather than NCURSES_CONST where X/Open

+ > merge branch begun April 2, 2017 which provides these features:
+ + support read/write new binary-format for terminfo which stores
+ numeric capabilities as a signed 32-bit integer. The test programs
+ such as picsmap, ncurses were created or updated during 2017 to use
+ this feature.
+ + the new format is written by the wide-character configuration of
+ tic when it finds a numeric capability larger than 32767.
+ + other applications such as infocmp built with the wide-character
+ ncurses library work as expected.
+ + applications built with the "narrow" (8-bit) configuration will
+ read the new format, but will limit those extended values to 32767.
+ + in either wide/narrow configuration, the structure defined in
+ term.h still uses signed 16-bit values.
+ + because it is incompatible with the legacy (mid-1980s) binary format,
+ a new magic value is provided for the "file" program.
+ + the term.5 manual page is updated to describe this new format.
+ + the limit on file-size for compiled terminfo is increased in the
+ wide-character configuration to 32768.
+
+20180120
+ + build-fix in picsmap.c for stdint.h existence.
+ + add --disable-stripping option to configure scripts.
+ + modify ncurses-examples to install test-scripts in the data directory.
+ + work around tool-breakage in Debian 9 and later by invoking
+ gprconfig to specify the C compiler to be used by gnatmake,
+ and conditionally suppressing Library_Options line for static
+ libraries.
+ + bump the compat level for test-packages to 7, i.e., Debian 5.
+
+20180106
+ + fixes for writing extended color pairs in putwin.
+ + modify test/savescreen.c to add test patterns that exercise 88-,
+ 256-, etc., colors.
+ + modify configure option --with-build-cc, adding clang, c89 and c99
+ as possible default values.
+ + modify ncurses-examples configure script to use pkg-config for the
+ extra form/menu/panel libraries, to be more consistent with the
+ handling of the curses/ncurses library.
+ + modify test-packages for mingw to supply "pc" files.
+ + modify gen-pkgconfig.in to list -lpthread as a private library when
+ configured to access it via weak symbols.
+ + simplify gen-pkgconfig.in, adding -ltinfo without the special linker
+ checks because some versions of the linker simply hard-code the
+ behavior.
+ + update URLs for ncurses website to use https.
+ + modify CF_CURSES_LIBS to fill in $cf_nculib_root in case the
+ ncurses-examples are built with a system ncurses that lacks the
+ standard "curses" symbolic link, as done by SuSE. The symbol is
+ needed to make a followup check for the pthread library work, and
+ would be set properly using the options "--with-screen", etc.
+ + generate misc/*.pc with "all" rule, as done for "sources" rule
+ (report by Jeffrey Walton).
+
+20171230
+ + build-fix for ncurses-examples with Fedora27, adding check for
+ reset_color_pairs() -- not yet in Fedora's package.
+ + consistently add $CFLAGS to $MK_SHARED_LIB symbol in configure
+ script when the latter happens to use the C compiler rather than
+ directly using the loader (report by Jeffrey Walton).
+ + set ABI for upcoming 6.1 release in "*.map" files. While there are
+ some remaining internals to apply, no ABI-related changes are
+ anticipated.
+ + add configure --with-config-suffix option to work around filename
+ conflict with Redhat packages versus test-packages.
+
+20171223
+ + modify ncurses-examples to quiet const-warnings when building with
+ PDCurses.
+ + modify toe to not exit if unable to read a terminal description,
+ e.g., if there is a permission problem.
+ + minor fix for progs/toe.c, using _nc_free_termtype2.
+ + assign 0 to pointer in _nc_tgetent_leak() after freeing it. Also
+ avoid reusing pointer from previous successful call to tgetent
+ if the latest call is unsuccessful (patch by Michael Schroeder,
+ OpenSuSE #1070450).
+ + minor fix for test/tracemunch, initialize $awaiting variable.
