HTTP_Adapter: allow body to be "omit"
In HTTP not all requests have a body. At the moment we describe a
missing body with body := "". This is not 100% correct since the rest of
the code interprets this as a present body with zero length and will put
a content_length = 0 header line into the HTTP header, even in the GET
request. This will most likely be ignored by any HTTP server, but it is
still not 100% spec compliant.
