uhd: Replace boost::function with std::function

This is mostly a search-and-replace operation, with few exceptions:
- boost::function has a clear() method. In C++11, this is achieved by
  assigning nullptr to the std::function object.
- The empty() method is replaced by std::function's bool() operator
