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

 # NCOPY tests
 
-Novell-only NCOPY tests.
+Automated NCOPY comparison tests for MARS NWE DOS tools.
+
+`NCOPY` is a larger copy/metadata tool.  The current test is designed to
+capture Novell behaviour first and compare the Open Source DOS utility against
+it before the implementation is completed.

-Use:
+`NCPTSTA.BAT` uses the same direction as the other tool tests:
+
+| Directory | Meaning |
+| --- | --- |
+| `OUT` | command output from Novell `NPUBLIC\NCOPY` |
+| `PUBOUT` | command output from Open Source `PUBLIC\NCOPY` |
+| `POSTNOV` | resulting file state captured with Novell tools |
+| `POSTPUB` | resulting file state captured with Open Source tools |
+| `COMPARE.LOG` | `FC` comparisons for command output and resulting state |

+## Current matrix
+
+The automated comparison covers:
+
+- `NCOPY /?`
+- `NCOPY` with no arguments
+- single-file copy with `TO`
+- copy of hidden/archive and read-only/archive files
+- `/V`
+- `/S`
+- `/S /E`
+- `/A /S`
+- `/M /S`, including source archive-bit readback
+- missing source
+- `/E` without `/S`
+
+The resulting destination/source state is checked with the already validated
+`FLAG`, `NDIR`, and `RIGHTS` tools.
