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

-# REVOKE baseline test
+# REVOKE comparison test
 
-Scripts:
+`RVKSTA.BAT` creates `F:\RVKTEST` and compares Novell `\NPUBLIC\REVOKE` output with the public implementation `\PUBLIC\REVOKE`.
 
-- `RVKSTA.BAT` creates `F:\RVKTEST`, uses Novell `\NPUBLIC\GRANT` for setup, then captures Novell `\NPUBLIC\REVOKE` output into `F:\RVKCMP\OUT`. User `MARIO` is used as trustee target.
-- `RVKZIP.BAT` packages `RUN.LOG`, `SUMMARY.TXT`, `SETUP`, and `OUT` as `F:\RVKCMP\RVKSTA.ZIP`.
+Result tree:
 
-Run as `SUPERVISOR` or an equivalent user with Access Control rights on `F:\RVKTEST`.
+- `F:\RVKCMP\OUT` - Novell baseline output
+- `F:\RVKCMP\PUBOUT` - public implementation output
+- `F:\RVKCMP\COMPARE.LOG` - direct `FC` comparisons
+- `F:\RVKCMP\UNOV` - user-context Novell `RIGHTS` readback
+- `F:\RVKCMP\UPUB` - user-context public `RIGHTS` readback
+- `F:\RVKCMP\UCOMP.LOG` - user-context `FC` comparisons
 
-Covered cases:
+The direct matrix covers:
 
-- help and no-argument grammar
-- normal directory revoke
-- `ALL` revoke / trustee removal
-- `/SUBDIRECTORIES` with trustees placed directly on child directories
-- `/FILES` on an explicit file and on a directory file set
-- relative path invocation from inside the test directory while invoking `\NPUBLIC\REVOKE` absolutely
-- no trustee, missing user, missing path behavior, `/FILES` plus `/SUBDIRECTORIES` option-combination behavior, and bad grammar
+- individual right removal: `R`, `W`, `C`, `E`, `M`, `F`, `A`, `S`
+- mixed rights removal such as `R F`, `R W C`, `E M F`, `S W C M`
+- `ALL` removal, which should delete the trustee entry
+- file-specific mode with `/FILES`
+- recursive directory mode with `/SUBDIRECTORIES`
+- missing trustee, missing user, missing path, invalid right, bad grammar, and `/FILES /SUBDIRECTORIES`
 
-This test is still Novell-baseline-only. Later comparison scripts should run the same command set through `NPUBLIC` and `PUBLIC` with normalized output.
+Automatic user-context readback requires:
 
-Notes from the first baseline run:
+```bat
+SET LGNTPWD=your-supervisor-password
+F:\RVKSTA
+```
 
-- `REVOKE /SUBDIRECTORIES` did not exercise child paths unless trustees existed on the child directories themselves, so `D20` now uses `SUBTST\S1` and `SUBTST\S2` with direct trustee setup.
-- Novell `REVOKE` may report `No trustee for the specified directory.` for a missing path before a separate missing-path diagnostic is reached; `D92` records that baseline behavior.
-- `D93` now uses an independent tree with directory, file, and subdirectory trustees so the `/FILES /SUBDIRECTORIES` option combination is tested without being masked by missing trustee setup.
-Retest focus after the fix:
+`RVKC.BAT` is queued via `DLYSTRT`, logs in as `NOPASSUSER`, captures `RIGHTS` output for the matrix cases, logs SUPERVISOR back in, and then starts `RVKSTA PART2` to copy and compare the user-context results.
 
-- `D20_SUBDIRS_REVOKE_CE.OUT` should no longer be masked by a missing trustee on the named root.
-- `D92_MISSING_PATH.OUT` records the exact Novell diagnostic for a missing path, even if that diagnostic is still `No trustee for the specified directory.`
-- `D93_FILES_AND_SUBDIRS.OUT` runs on a prepared tree with directory, file, and subdirectory trustees, so the `/FILES /SUBDIRECTORIES` combination is no longer masked by setup.
+`RVKZIP.BAT` packs the result tree and cleans `F:\RVKTEST` and `C:\RVKTMP`.
