Facilitate SDCH content decoding after a proxy removes ALL content info
Facilitate SDCH content decoding after a proxy removes ALL content info

Some proxies remove all content-encoding information when they see
that SDCH encoding was done.  We had a premature optimization that
only called for doing "fixups" of content encoding IF there was
some content encoding.  We need to do the fixups as needed even
if the HTTP headers didn't supply any encodings (such as when
a proxy or anti-virus software strips all encodings!)
