- add `usage'; displays the usage of a command. implemented by calling the c_handler() with argc = 0, argv = "funcname". - add `passive auto'; does the same as $FTPMODE=auto. - add `set [option value]'; display all options, or set an option to a value. - add `unset option'; unset an option. - add getoptionvalue() to retrieve an option's value, and replace a few global variables with calls to this. - implement cleanuppeer(), which resets various bits of state back to `disconnected'. call in disconnect() and lostpeer(). - support completing on `options'. - improve recovery after a SIGINT may have closed the connection. XXX: there's still a couple to fix other stuff: - various consistency fixes in the man page. - ensure that the command usage strings in the code and man page match reality. - mput/mget: check that the connection still exists before each xfer. - minor cosmetic changes in confirm(). - set code correctly in sizecmd() and modtime() - don't need \n in err() strings. - change lostpeer to take an argument (rather than casting (sig_t)lostpeer in signal handlers) - knf and whitespace police.
