* fixed quite a number of small issues and things that weren't
quite right.
* No user visible changes

- Update to version 2.1.5
* You can now set permissions on unix socket files
* gtlssh-keygen was extended to make it easier to install new
keys and transfer them to other systems on a key update.
Basically, you can generate a new key then issue a command to
copy them to other systems using the old key.
* gtlsshd was fairly broken handling passwords if you didn't get
the first one right. I don't use passwords very much, and I
haven't figured out a way to automate tests on it. But it
should work ok now.
* Fix some minor bugs and a possible (low probability) crash in
stdio.
* Add some tcpd capability for setting th ename per-gensio.
