uhd: replaced std::vector<type> for buffer arguments in send/recv

Created new type ref_vector for representing a vector of pointers.
Can be created from std::vector or a pointer.

Removes the convenience constrcutors for send/recv, its not needed.

Removes malloc/free overhead when using send/recv with pointer.
