* replace all uses of fgets() + LINE_MAX by read_line()
-* fix logging in execute.c: extend log.c to have an optional mode where
- log_open() is implicitly done before each log line and log_close() right
- after. This way we don't have open fds around but logs will still
- work. Because it is slow this mode should used exclusively in the execute.c
- case.
-
* set IPAddressDeny=any on all services that shouldn't do networking (possibly
combined with IPAddressAllow=localhost).
