server level url rewrite & config rewrite or internal redirection cycle

[et]

Thanks Igor.

You can say it's over-engineering. But make the cycle number controlled by the user should be reasonable and a trivial work.

I also suggest to mention in the doc of rewrite module that the 'break'/'last' flag not supported on the server level config.
