dosutils: add Novell-style paging to FLAG tools and SLIST

- add a shared DOS pager helper for long tool output
- page FLAG wildcard output with the Novell continue prompt
- fix FLAGDIR current-directory handling for "." and volume root
- add FLAGDIR wildcard directory listing support
- page FLAGDIR wildcard output like Novell FLAGDIR
- keep FLAGDIR display formatting aligned with Novell output
- make SLIST /CONTINUE enable continuous output
- keep SLIST bindery scanning compatible with ncpfs behavior
- preserve SLIST NET_ADDRESS display and default server marking
