civetweb frontend fails authentication if URL has special chars
For example trying to initiate a multipart to a 'test:multi' key.

The URL part is clearly wrong. It's been urldecoded by civetweb somewhere and shouldn't have been.

The problem is that civetweb only give the url-decoded URI in the
struct mg_request_info. I don't see how you can get the original version at all. And you can't just re-encode it because there is several url-encoded version that match the same url-decoded version and the S3 auth relies on the original one in the request, however it was encoded.
I don't see how to resolve this without patching civetweb to not URL decode.
