* Update to 7.80

* Add "full" variants for nmap and ncat that support Lua scripts (and
  OpenSSL)

* Replace libcxx fix with upstream patch[1] (CHANGELOG change was
  removed)

* Switch ndiff to use Python 3 (using a patch from Debian[2], which
  comes from an upstream PR[3] plus a port of ndiff/setup.py)
