2.17.8 Stuff:

- In gdmlogin, change "Session" mnemonic to "e" instead of "s"
 so it doesn't conflict with the "Start Again" button.
- Now AlwaysLoginCurrentSession is set to true by default.

- Fix spacing in gdmsetup so it uses less vertical space.  (Lukasz
 Zalewski)

- Fix gdmchooser so it builds with HURD.

- Fix comparison with string literal in gdmdynamic.  (Hans Petter
 Jansson)

- On Solaris, gnome.session script calls /usr/dt/config/Xsession.jds
 instead of gnome.session since Xsession.jds starts D-Bus daemons
 needed for GNOME to run properly.  (Brian Cameron)

- Translation updates (Takeshi AIHANA, Josep Puigdemont i Casamaj\303\263,
