r11095: Implement wb_getuserdomgroups.

Tridge, if you have the time, you might want to look at a problem I'm having
with unix domain stream sockets. From a comment in this commit:

	/* Using composite_trigger_error here causes problems with the client
	 * socket. Linux 2.6.8 gives me a ECONNRESET on the next read after
	 * writing the reply when I don't wait the 100 milliseconds. */

This is in winbind/wb_cmd_userdomgroups.c:93.

The problem I have is that I can not *immediately* send an error reply to the
client because the next receive fails. Waiting 100 milliseconds helps. It
might also be a problem with epoll(), I don't really know.

I'd appreciate if you took a brief look at this, maybe I'm doing something
wrong.

Thanks,

Volker
