nullptr+0 is an UB (undefined behavior).
- Fixing my_string_metadata_get_mb() to handle {nullptr,0} without UB.
- Fixing THD::copy_with_error() to disallow {nullptr,0} by DBUG_ASSERT().
- Fixing parse_client_handshake_packet() to call THD::copy_with_error()
with an empty string {"",0} instead of NULL string {nullptr,0}.
