Fix unsafe and inefficient uses of copy_string

Browse source 
Add a new overload to `copy_string` that takes the input characters plus
size. The new overload avoids inefficient scanning of the input for the
null terminator in cases where we know the size beforehand. Furthermore,
this overload *must* be used when dealing with input character sequences
that may have no null terminator, e.g., when the input is from a
`std::string_view` object.
