Perform some assertions about the behavior of parsing and

value, assert that the parsed form contains all the available
information with the correct structure; generate the HTTP
header value from the parsed form, assert that it contains
certain literal strings; finally, re-parse the generated HTTP
header value and assert that the resulting structured data is
the same as the first-pass parsed form.

@param headername: The name of the HTTP header L{table} contains values for.
@type table: A sequence of tuples describing inputs to and
outputs from header parsing and generation. The tuples may be
either 2 or 3 elements long. In either case: the first
element is a string representing an HTTP-format header value;
the second element is a dictionary mapping names of parameters
to values of those parameters (the parsed form of the header).
If there is a third element, it is a list of strings which
must occur exactly in the HTTP header value
string which is re-generated from the parsed form.
