…n header keys

This was originally done in https://codereview.appspot.com/5690059
(Feb 2012) to deal with bad response headers coming back from webcams,
but it presents a potential security problem with HTTP request
smuggling for request headers containing "Content Length" instead of
"Content-Length".

Part of overall HTTP hardening for request smuggling. See RFC 7230.

Thanks to Régis Leroy for the report.
