Technical notes on version 2.1
General:
+16Jun07
+kes Remove a few malloc()s from the encryption code.
+kes Use the class calls to bsock in filed/backup.c and restore.c in
+ place of the old bnet_xxx code.
+kes Implement code that does an on the fly calculation of the
+ signing digest during restore of encrypted files. It makes
+ a best guess at the algorithm, and if it is not correct, will
+ then revert to the old code which reads the file after it is
+ restored.
+kes Implement at least one missing crypto stream in stream_to_ascii()
+kes Apply patch from William <chowmeined@gmail.com> that fixes bug
+ #877 where a reload with bad syntax causes Dir to exit.
