Added tests 1071 through 1074 to test automatic downgrading from HTTP 1.1

to HTTP 1.0 upon receiving a response from the HTTP server.  Tests 1072
and 1073 are similar to test 1069 in that they involve the impossible
scenario of sending chunked data to a HTTP 1.0 server.  All these currently
fail and are added to DISABLED.

Added test 1075 to test --anyauth with Basic authentication.
