Special case HTTP 0.9 early on

Browse source 
Mostly, treat HTTP0.9 completely separate. Because we're doing raw
delivery of a body directly, fake enough (connection_close=1, and finish
headers manually) so that the MIME infrastructure thinks it is seeing a
body.

This deals better with the body due to accounting for the first line. Also
it avoids the content line analyzer to strip CRLF/LF and the analyzer
then adding CRLF unconditionally by fully bypassing the content line
analyzer.

Concretely, the vlan-mpls test case contains a HTTP response with LF only,
but the previous implementation would use CRLF, accounting for two many bytes.
Same for the http.no-version test which would previously report a body
length of 280 and now is at 323 (which agrees with wireshark).

Further, the mime_type detection for the http-09 test case works because
it's now seeing the full body.

Drawback: We don't extract headers when a server actually replies with
a HTTP/1.1 message, but grrr, something needs to give I guess.
