Fix hang on Gzip decompression

'LimitedInputFilter' should be applied before the Gzip middleware as
'CONTENT_LENGTH' refers to the size of the *compressed* body.  If
applied in wrong order, this may cause 'copyfileobj()' to try to read
more data from the socket than is available, resulting in a call to
'recv()' that hangs forever.
