- Add ncurses patch 20170513
+ add test/picsmap.c to fill in some testing issues not met by dots.
The initial version reads X bitmap (".xbm") files.
+ repair logic which forces a repaint where a color-pair's content is
changed (cf: 20170311).
+ improve tracemunch, showing screenXX pointers as names.

- Better screen support and workaround about missing terminfo entries
might be help on boo#812067 as well as on boo#935736 but may cause
boo#940459 (which should be fixed by screen its self!)
- New package terminfo-screen which includes some useful but troubling
terminfo database entries for screen.

- Disable the usage of getttynam(3) as under Linux this is not used
