Ways of handling problematic WARC records

[anjackson]

We've found some weird WARCs, looking like this:

WARC/1.0
WARC-Type: response

WARC-IP-Address: 176.58.112.27

which comes out as a malformed CDX record:

But I think it'd be better to skip/drop these records?

We also have redirects that point back to the web archive, that PyWB is unable to deal with (webrecorder/pywb#591) - it would be great to be able to filter our records because they redirect to a particular host (www.webarchive.org.uk in this case).
