This patch makes a slight change in the way CONSOLE_LOG_FAST and CONSOLE_LOG_ALL are differentiated, by no longer passing a different tx_byte() function pointer and instead using the `data` argument to vtxprintf() to encode the difference. It also passes the message log level through to the tx_byte() function this way, which will be needed in the next patch.
