change error handling for bad resp headers

 - avoid looping between ap_die and the http filter
 - remove the header that failed the check
 - keep calling apr_table_do until our fn stops matching


This is still not great. We get the original body, a 500 status
code and status line.

Follow up to r1773293.
When check_headers() fails, clear anything (headers and body) from original/errorneous
response before returning 500.


Follow up to r1773761: don't check_headers() more than once.

Follow up to r1773761: don't recurse on internal redirects.

Follow up to r1773761: don't recurse on ap_send_error_response() either.
