	* configure.in, acconfig.h, daemon/auth.c, daemon/misc.[ch],
	  daemon/slave.c, daemon/verify.h,
	  daemon/verify-(pam|crypt|shadow).h:  Fixup enviroment issues.
	  Clear the environment before running a session and before launching
	  the greeter (taking care to save the localisation vars).  Also
	  don't set user env on the slave and leave it, if we set it it's
	  only temporary.  Also fix one possible crash by strduping the
	  pam env since that will go away and putenv doesn't strdup.
