The text input control_event was initially designed for mapping SDL_TextInputEvent, limited to 32 characters. For simplicity, the copy/paste feature was implemented using the same control_event: it just sends the text to paste. However, the pasted text might have a length breaking some assumptions: - on the client, the event max-size was smaller than the text max-length, - on the server, the raw buffer storing the events was smaller than the max event size. Fix these inconsistencies, and encode the length on 2 bytes, to accept more than 256 characters. Fixes <https://github.com/Genymobile/scrcpy/issues/10>.
