Add function-level comments to the low-level NCP wrapper functions in
ncpcall.c.
Document each wrapper's purpose, NCP function/subfunction, requester path and
return behavior. The descriptions are based on the existing implementation and
cross-checked against the MARS-NWE admin sources and Novell SDK/WebSDK
references.
No behavior change.
Rename the bindery access level wrapper from ncp17_46_get_bindery_access_level()
to ncp14_46_get_bindery_access_level().
The previous rename made the operation look like a normal NCP17 bindery wrapper,
but the historic implementation used the ncp_14_46 naming. Keep that protocol
reference visible while retaining the descriptive operation name.
No behavior change.
Rename the low-level NCP wrapper functions in ncpcall.c and net.h to include
both the NCP function/subfunction number and the operation they perform.
This keeps the numeric protocol reference visible for comparison with SDK
documentation and MARS-NWE logs, while making call sites easier to understand.
Update all callers to use the new names.
No behavior change.
Add GPL-2-or-later license headers to the DOS utility source files and
document the purpose and local dependencies of each C, header and assembler
file.
Preserve the original Martin Stover copyright attribution for the historic
MARS-NWE utility sources, including files that did not previously carry an
explicit header but are part of the original tool set. Add Mario Fetka as the
2026 copyright holder for the current maintenance work, and use Mario-only
headers for files without original Martin Stover ownership.
Also add a root-level COPYING file containing the GPL-2 license text.
