XmlRpcPlugin does not work with Trac 0.10.1 due to CSRF fix.

[Shun-ichi Goto <shunichi.goto@…>]

The form_token cookie introduced in Trac 0.10.1 prevents
XML-RPC access because it cannot get valid cookie and
all the POST request is checked before handler is called.
So ​XmlRpcPlugin does not work at all.

For local workaround, I patched to exclude content-type: text/xml
but it is not considered for security aspects.
What is the right way?
