	    Integrate elliptic curve contribution from Andreas
	    Schultz </p>
          <p>
	    In order to be able to support elliptic curve cipher
	    suites in SSL/TLS, additions to handle elliptic curve
	    infrastructure has been added to public_key and crypto.</p>
          <p>
	    This also has resulted in a rewrite of the crypto API to
	    gain consistency and remove unnecessary overhead. All OTP
	    applications using crypto has been updated to use the new
	    API.</p>
          <p>
	    Impact: Elliptic curve cryptography (ECC) offers
	    equivalent security with smaller key sizes than other
	    public key algorithms. Smaller key sizes result in
	    savings for power, memory, bandwidth, and computational
	    cost that make ECC especially attractive for constrained
	    environments.</p>

          <p>[httpc] Wrong Host header in IPv6 HTTP requests.
	  When a URI with a IPv6 host is parsed, the brackets that encapsulates
	  the address part is removed. This value is then supplied as the host 
	  header. This can cause problems with some servers.
	  A workaround for this is to use headers_as_is and provide the host
	  header with the requst call. 
	  To solve this a new option has been added, 
	  <seealso marker="httpc#ipv6_host_with_brackets">ipv6_host_with_brackets</seealso>. 
	  This option specifies if the host value of the host header shall 
	  include the brackets or not. By default, it does not (as before).

	    [httpc] If a request times out (not connect timeout), the
	    handler process exited (normal) but neglected to inform
	    the manager process. For this reason, the manager did not
	    clean up the request table., resulting in a memory leak.
	    Also the manager did not create a monitor for the
	    handler, so in an unforseen handler crash, this could
	    also create a memory leak.</p>

            be used in situations where a long term HTTP connection is used to 
            send periodic status updates as individual chunks.  Previously a

                  this is no longer a synchronous operation. Previously, 
                  the new request handler made the connection to the 
                  server and issuing of the first request (the reason 
                  for starting it) in the gen_server init function. 
                  If the connection for some reason "took some time", 
                  the manager hanged, leaving all other activities by 
                  that manager also hanging. </p>

          <p>These functions is documented as working on directories, but 
            this is actually not according the standard. The LIST and NLST
            commands are specified to operate on a directory or other 
            group of files, or a file.</p>
          <p>Previously, an attempt was made to check if the listing
            returned by the server was actually an error message. This
            was done by changing remote directory (cd) into the 
            (assumed) "directory". This may work if Pathname was actually 
            a directory, but as this is not always the case, this test 
            does not work. Instead, we now return the actual server 
            result and leave the interpretation to the caller. </p>

            When http:request is called and httpc_manager selects a session

            it for the response to the second request. But if there are still 
            some inbound packets for the response to the first request, things 
            get confused.</p>
