[libmicrohttpd] Broken HTTP 1.0 and 0.9 support

[Geoffrey McRae]

Hi All,

I am one of the developers for XBMC where we are using your wonderful
library for our web interface. It has come to my attention however that
support for HTTP/1.0 and 0.9 is broken/wrong.

Currently 0.9 for requests it serves out an invalid " 200 OK" and the
headers, which it should not.

For 1.0 it returns HTTP/1.1 in the response, which again is incorrect
since we made a 1.0 request.

The following patch corrects both of these issues.

Kind Regards
