Let's be more careful with what we serialize: let's ensure we never serialize strings that are longer than LONG_LINE_MAX, so that we know we can read them back with read_line(…, LONG_LINE_MAX, …) safely. In order to implement this all serialization functions are move to serialize.[ch], and internally will do line size checks. We'd rather skip a serialization line (with a loud warning) than write an overly long line out. Of course, this is just a second level protection, after all the data we serialize shouldn't be this long in the first place. While we are at it also clean up logging: while serializing make sure to always log about errors immediately. Also, (void)ify all calls we don't expect errors in (or catch errors as part of the general fflush_and_check() at the end.
