- boost::lexical_cast -> std::stod / std::to_string - boost::format -> string concatenation - boost::bind -> C++14 lambdas with explicit captures - boost::mutex / scoped_lock -> std::mutex / std::lock_guard - boost::uint32_t -> std::uint32_t - drop <boost/bind.hpp>, <boost/lexical_cast.hpp>, <boost/weak_ptr.hpp> - drop find_package(Boost), Boost link flags, and BOOST_ALL_DYN_LINK - macports CI: pass UHD's boost171 include dir via CMAKE_CXX_FLAGS, since MacPorts UHD public headers still include <boost/config.hpp> Rebased onto current upstream master (UHD 4.x, modernized CMake). Property-tree publisher/subscriber callbacks use set_publisher() / add_desired_subscriber() with lambdas, matching upstream's API surface after the UHD <4.0 support drop.

The Boost utilities replaced here all have C++14 equivalents.
UHD's CMake config still pulls
Boost_INCLUDE_DIRStransitively viafind_dependency(Boost)inUHDConfig.cmake, so UHD public headers that template-instantiate Boost types (e.g.uhd::dictindict.ipp) keep compiling.
