This series changes the local_device_setup function and the resume
script so that we wait for a resume device to appear, same as for
the root and /usr devices. However, it is not a fatal error if
the resume device doesn't appear (which would be a regression).
Also, it makes the time limit global (using /proc/uptime) so that
this change doesn't increase the time for a panic shell to appear
in case both the resume and root devices don't appear. This could
cause a regression for mdadm, as its local-block script has a gross
hack to count how many times we run it and to do something different
when it looks like we're 2/3 of the way to the timeout. That would
probably need to be resolved somehow before we make this change.
