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

 # CREATOR / xattr automated test
 
-This replaces the old FILER/manual creator-xattr test with a direct test using
-`PUBLIC\CREATOR.EXE`.
+This test validates `PUBLIC\CREATOR.EXE` against the MARS-NWE file metadata
+stored in Linux extended attributes.  It also performs an optional readback as
+`NOPASSUSER`, so the generated metadata and effective rights can be checked from
+a normal-user context.
 
 ## Requirements
 
-`PUBLIC\CREATOR.EXE` from the new dosutils tree must be installed.
+Install the current DOS tools into the normal test locations:
+
+```text
+SYS:PUBLIC\CREATOR.EXE
+SYS:PUBLIC\RIGHTS.EXE
+SYS:PUBLIC\DLYSTRT.EXE
+SYS:NPUBLIC\NDIR.EXE
+SYS:NPUBLIC\RIGHTS.EXE
+SYS:NPUBLIC\FLAG.EXE
+SYS:NPUBLIC\GRANT.EXE
+```
+
+For the Linux collector install the `attr` package, so `getfattr` is available.
+
+The optional user-context phase expects these accounts to exist:
+
+```text
+SUPERVISOR
+NOPASSUSER
+MARIO
+```
+
+`MARIO` is used as the creator/modifier/archiver object name in the test data.
+
+## Files used by the test
+
+All DOS scripts are expected at the root of `F:`:
+
+```text
+F:\CIXSTA.BAT
+F:\CIXC.BAT
+F:\CIXZIP.BAT
+```
+
+`CIXC.BAT` and `DLYSTRT.EXE` are copied to `C:\CIXTMP` before the delayed
+logout/login helper is started.  `CIXSTA.BAT` stays on `F:` and is run again as
+`F:\CIXSTA.BAT PART2` after the helper has logged `SUPERVISOR` back in.
+
+Generated directories:
+
+```text
+F:\CIXTEST        test tree
+F:\CIXCMP         result tree
+C:\CIXTMP         temporary local helper/output directory
+```

+
+Without `LGNTPWD`, the Supervisor-only CREATOR/xattr part can still be run, but
+the delayed user-context phase is skipped.
