[issue2551047] REST-API not working with wsgi

New submission from Ralf Schlatterbeck:

The rest implementation uses several calls to client.request.headers.
In WSGI 'request' is a RequestDispatcher object from
roundup/cgi/wsgi_handler.py
This object doesn't have a 'headers' attribute.

My naive implementation of a headers object would be to take the header
name, convert it to uppercase and replace '-' with '_', prefix it with
HTTP_ and look it up in the CGI environment. Is this an acceptable
solution? Alternatives, better ideas?

I found a google groups article that goes into the same direction:
https://groups.google.com/forum/#!topic/modwsgi/swJmEP79Pds

Traceback when calling rest uri with WSGI:
Traceback (most recent call last):
  File
"/usr/local/lib/python2.7/dist-packages/roundup/cgi/wsgi_handler.py",
line 74, in __call__

    headers = self.client.request.headers
