uhd: Replace usage of boost smart pointers with C++11 counterparts

This removes the following Boost constructs:
- boost::shared_ptr, boost::weak_ptr
- boost::enable_shared_from_this
- boost::static_pointer_cast, boost::dynamic_pointer_cast

The appropriate includes were also removed. All C++11 versions of these
require #include <memory>.
Note that the stdlib and Boost versions have the exact same syntax, they
only differ in the namespace (boost vs. std). The modifications were all
done using sed, with the exception of boost::scoped_ptr, which was
replaced by std::unique_ptr.

References to boost::smart_ptr were also removed.

boost::intrusive_ptr is not removed in this commit, since it does not
have a 1:1 mapping to a C++11 construct.
