[PATCH] url: Wrap cookie headers in url-http--encode-string.

From: Toke Høiland-Jørgensen
Subject: [PATCH] url: Wrap cookie headers in url-http--encode-string.
Date: Wed, 7 Sep 2016 17:30:14 +0200

In some cases the output of url-cookie-generate-header can be multibyte,
which will trip the length check that was added at the end of
url-http-create-request. This seems to happen only when there's a
request body which contains UTF-8-encoded non-ASCII characters.
