For better readability, "pactl list message-handlers" is introduced which prints a formatted output of "pactl send-message /core list-handlers". The patch also adds the functions pa_message_params_read_raw() and pa_message_params_read_string() for easy parsing of the message response string. Because the functions need to modify the parameter string, the message handler and the pa_context_string_callback function now receive a char* instead of a const char* as parameter argument.
