Summary:
Some browsers will still sniff content types even with "Content-Type" and
"X-Content-Type-Options: nosniff". Encode "<" and ">" to prevent them from
sniffing the content as HTML.
See T865.
Also unified some of the code on this pathway.
Test Plan: Verified Opera no longer sniffs the Conduit response into HTML for
the test case in T865. Unit tests pass.

Summary:
This addresses a few things:
- Provide a software HTTP response spliting guard as an extra layer of
security, see http://news.php.net/php.internals/57655 and who knows what HPHP/i
does.
- Cleans up webroot/index.php a little bit, I want to get that file under
control eventually.
- Eventually I want to collect bytes in/out metrics and this allows us to do
that easily.
- We may eventually want to write to a socket or do something else like that,
ala Litespawn.
Test Plan:
- Ran unit tests.
- Browsed around, checked headers and HTTP status codes.
