commit a914187b5f2efb214ca2a41b1fe087d9d9833a32
Author: Ray Strode <rstrode redhat com>

Make greeter explicitly request PAM conversation
Now the greeter has to say what PAM stack it wants the slave to
run. When that stack is ready, we emit the Ready signal as
before, but now the Ready signal carries a string argument
saying which service is ready to converse.
When we support multiple PAM stacks, the greeter will call
StartConversation for each stack, and will keep the UI
associated with each stack disabled until the Ready signals
come back one-by-one.
