[DGD]1.1.82

There is no dgd/src/Changelog entry this time, it is all kernel
lib changes.

A summary of kernel lib changes for this release and the previous
one combined:

 - connection->set_user() and user->redirect() no longer return a
   value;
 - user->message_done() must now return an integer mode value, just
   like login() and receive_message();
 - connection->block_input() has been removed; instead, the blocking
   of input is now fully handled by connection->set_mode();
 - Three new mode values, MODE_LINE, MODE_NOCHANGE and MODE_UNBLOCK.
   MODE_LINE is identical to MODE_ECHO, and should be used for binary
   connections where MODE_ECHO is less meaningful.  MODE_NOCHANGE
   continues in the current connection mode, whatever it was.
   MODE_UNBLOCK reverts the mode to whatever it was before it was
   set to MODE_BLOCK.
   The numeric value of MODE_BLOCK has changed!  All objects using it
   should be recompiled.

If you are using the kernel lib but don't know what this is all about,
this change won't affect you.

Dworkin
