dosutils: align Novell-compatible tests and stage NCOPY work

Update the DOS utilities and test suite with the current Novell comparison
state.

Validated/updated tool behavior:
- improve CREATOR output by showing Novell-style attribute and rights masks
- extend FLAGDIR handling with old NCP22 directory attribute read/write
  fallback paths
- expand NDIR Novell-style formatting, filtering, /SUB handling, date output,
  DI/RI attribute display and richer metadata collection
- adjust REVOKE output/grammar, recursive /SUBDIRECTORIES behavior and trustee
  update/delete paths to better match Novell tools
- adjust SLIST header/output behavior for logged-in and logged-out cases
- update README status to reflect the currently green/tested tools

Test-suite changes:
- add/refresh Novell comparison tests for CREATOR, NDIR, REVOKE and SLIST
- update NCOPY tests and collection scripts for the current investigation state
- refresh per-tool README files and top-level test documentation
- keep MAP documented as still separately open

NCOPY:
- add the current NCOPY implementation and experimental NCP74/server-side-copy
  scaffolding
- build ncopy.c so it stays compile-tested
- keep NCOPY disabled in the NET multicall dispatch for now because the
  server-side-copy/open-handle path is still unsafe and needs further analysis

Build:
- include ncopy.c in the DOS utility build
- drop the temporary MARS_DOSUTILS_VERSION define wiring from CMake
