>    databases/mysql81-server: fix build with libc++ 19
>    
>    As noted in the libc++ 19 release notes [1], std::char_traits<> is now
>    only provided for char, char8_t, char16_t, char32_t and wchar_t, and any
>    instantiation for other types will fail.
>    
>    This causes databases/mysql81-server to fail to compile with clang 19
>    and libc++ 19, resulting in errors similar to:
>    
>        /usr/include/c++/v1/string:820:42: error: implicit instantiation of undefined template 'std::char_traits<unsigned char>'

>    `Key_string` is defined as `std::basic_string<unsigned char>`, which is
>    no longer possible. So redefine it as a `std::vector<unsigned char>`
>    instead.
>    
>    This requires only a few small adjustments in other places: replacing
>    the `length()` method with the equivalent `size()` method, and adjusting
>    the arguments for the `assign()` method, which for `std::vector` takes a
>    begin and end iterator, instead of a begin iterator and a size.
