- Included from upstream source archive distribution:
    * Sources from "libarchive/" directory, excluding manpages,
      tests and build files
    * "COPYING" from archive root
    * Configuration headers in "3rdparty/libarchive/config/*" are
      pre-generated from "build/cmake/config.h.in"

- Add project files for qmake, document usage of library in
  "3rdparty/libarchive/qt_attribution.json".
- Update build instructions for Coin.
- Support for libarchive can be enabled or disabled with the
  "libarchive" configuration feature.
- Update "Getting Started" page in documentation.
