Merge of r4636, r4637, r4638: config sanity checks.
*) Added syntax checking of the second parameter of the "split_clients"
directive.
*) Capped the status code that may be returned with "return" and
"try_files".
*) Zero padded the returned and logged HTTP status code, and fixed possible
buffer overrun in $status handling.
