ncurses 6.1 - patch 20190317

+ regenerate llib-* files.
+ modify tic to also use new function for user-defined capability info.
+ modify _nc_parse_entry() to check if a user-defined capability has
  an unexpected type; ignore it in that case.
+ fix a special case of link-anchors in generated Ada html files.
+ use newer rel=author tag in generated html rather than rev=made,
  which did not become accepted.
