Bug#23750 disable sending latin-1 or utf-8 body

[Knut Olav Bøhmer]

In url-http.el there is a function url-http-create-request with the
following check:

    ;; Bug#23750
    (unless (= (string-bytes request)
               (length request))
      (error "Multibyte text in HTTP request: %s" request))
    (url-http-debug "Request is: \n%s" request)

It makes it impossible to send utf-8 or latin-1 strings in the body.
I need it for some requests by soap-client.
Would be nice If we could have an extra variable to allow latin-1 strings.
For example  url-http-allow-multibyte-body or
url-http-prevent-multibyte-request, or something like that.

then do

    (unless (and url-http-prevent-multibyte-request (= (string-bytes
request)
               (length request)))
      (error "Multibyte text in HTTP request: %s" request))

Or maybe the solution is something else. But it should be possible to send
latin-1 strings  with "æøå" in it.
