aae38d10b4
Among the changes from before: - Add support for extended colors on widechar version - Enable ncurses extended functions - Enable version 2 of the extended mouse support - Enable SCREEN extensions Modification that differs from upstream: - _nc_delink_entries used to be exposed and was turn static, turn it back as dynamic to not break abi - Adapt our old termcap.c to modern ncurses MFC after: 3 weeks
