cmake: Bump dependency versions for UHD 4.0.0.0

- Boost >= 1.58
- CMake >= 3.5.1
- gcc >= 5.4.0
- Clang >= 3.8, AppleClang >= 600
- Python >= 3.5 (Py2k no longer supported)
- Numpy >= 1.11
- C++14 for lib, include may now use C++11 constructs.
  - Because there is no more code requiring C++03 syntax, we remove the
    include-specific clang-format file
