c2a2a15c12 document the return value expected from the callback given to iob_write
remove unused #include in iob_reset
if iob_addfile_close fails, it now closes the fd

if iob_addbuf_free fails, it now frees the buf

zero a buffer in io_passfd so valgrind does not complain when we pass it

51202765fe the #define extern hack in io_fd.c also included time.h, fix that
catch case in timeout loop where we have something to report on an fd;
in that case do not report a timeout but let the other event get through
first.
