- Add TORRENT_WITHOUT_NCURSES macro in scripts/checks.m4
- Clear CURSES_LIBS/CFLAGS in the macro instead of if/else in configure.ac
- Restore simple LIBS/CFLAGS lines in configure.ac
- Add missing set_escdelay stub
Add a dummy curses stub header that provides all ncurses types, macros,
and no-op function stubs. When configured with --without-ncurses, the
build uses this stub instead of linking to the real ncurses library.
This allows rtorrent to be built for daemon-only usage (e.g. with
ruTorrent or Flood) without requiring ncurses to be installed.
