Add a NetWare-style FLAGDIR implementation for directory attributes and
register it in the multi-call DOS utility dispatcher. The new command
supports the 386-style directory flags Normal, System, Hidden,
DeleteInhibit, Purge and RenameInhibit, and formats output close to the
Novell FLAGDIR tool for simple mapped paths.
Update the DOS utilities install/build metadata so flagdir.exe is emitted
alongside the other public tools. Adjust the Open Watcom CMake build to
compile C sources into the build directory instead of leaving object files
in the source tree.
Move the historical Borland/TASM build files into doc/ to keep the active
source directory focused on the modern Watcom/CMake build.
Implement a working DOS Client32 NCP87 path using the NIOS resolver,
CONNOpenByReference and COMPATNcpRequestReply.
Add an initial FLAGDIR implementation for NetWare 386-style directory
attributes. Support Normal, System, Hidden, Delete Inhibit, Purge and
Rename Inhibit, using the same Client32 NCP87 modify/read helpers. Match
the Novell FLAGDIR display style more closely for simple mapped paths.
Also add/keep minimal TESTS coverage for the verified Client32 NCP87
attribute path.
