Zygo Blaxell fb0e676ee8 string: drop vector_copy_struct, obsoleted by ByteVector
vector_copy_struct constructed a std::vector<uint8_t> from a fixed-size
struct.  ByteVector replaces std::vector<uint8_t> and has a template
constructor which does the same thing as vector_copy_struct, so there
is no longer a need for this function.
