Serialise a message once and cache the result in the lo_message, so repeated lo_send_message() calls with the same path send the cached bytes with no allocation or re-serialisation. With buf == NULL liblo owns the cache; otherwise the caller keeps ownership (allocation-free path). The cache is invalidated by any lo_message_add_*()/clear() and freed by lo_message_free(); a different path re-serialises transparently. Implements the lo_message-centric approach discussed in radarsat1#75. Only appends fields to the internal _lo_message, so it stays ABI-compatible. Adds the Windows .def export and a test_freeze() case. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
