Supply ALE with HttpReply before checking http_reply_access (#398)

Supply ALE with HttpReply before checking http_reply_access (#398)

Before this fix, Squid warned "ALE missing HttpReply object",
because ALE::reply was initialized too late. This problem affected
both HTTP and FTP code paths.

To avoid these problems, ALE::reply is initialized early with the
available (received) response.

Also:

* Fixed logging control (1xx) responses in case these responses
  are final. Before this fix, '-' was logged.

* All reply headers ('<h') were logged with a single CR separator,
  instead of CRLF.

* Supply ALE for send_hit ACL. cb36505 already covered many (but not
  all) similar cases.
