    Attachment: 0001-Fix-OAuth-that-broke-with-parameters-in-rewrites.patch

The attached patch includes a fix and a test case that allows for reproducing the issue.

> When a rewrite rule containing a var ( such as /:name/myfunction ) matches an incoming
request then an additional query param gets created. Unfortunately this new query param gets
included in the Signature Base String when the OAuth code generates its version of the request
signature to validate the incoming request it causing authentication to fail.
> To fix this isn't straightforward. When a VHost is configured there is a handy copy of
the original URL in (x-couchdb-vhost-path) that can be used to generate the Signature Base
String, unfortunately if there isn't a VHost no such copy exists.
