+ == Fedora 28 Boost 1.66 upgrade

+ *Boost* has been upgraded to version 1.66. Apart from a number of bugfixes and improvements to existing libraries, this brings several new libraries compared to Fedora 27: `Boost.PolyCollection`, `Boost.Stacktrace`, `Boost.Beast`, `Boost.CallableTraits`, `Boost.Mp11`.

+ 

+ One library has been removed, `Boost.TR1`, and a number of deprecated APIs in `Boost.Asio` have been removed. Code using `Boost.TR1` should be modified to use the equivalent features provided by other Boost libraries (e.g. `Boost.Tuple`, `Boost.Unordered`) or in the C++ standard library (e.g. `std::tuple`, `std::unordered_map`). Code using the deprecated Asio APIs should be modified by removing the `io_service` arguments.
