Log rotate

I found that the log rotate function was doing a lot more than rotating
the logs and causing squid to effectively shutdown for long periods (30
seconds or more). I also changed the logging so that it doesn't abort
and core if it can't write a log file. Here's the patch to trim the
rotate down to size.
