Fix issue #26879170: Adjust doze maintenance windows...

...based on network availability

There is a new light maintenance state "waiting for network"
that we go in to after idle if the network is not currently
available.  We will stay in this state the same duration as idle,
so if we are continually without network access this effectively
doubles the light doze idle durations.

Get rid of some wrongly copy/pasted code to allow doze light
to still work even if we don't have an SMD.  It doesn't need
one.

Also a bunch of improvements to the shell commands to make it
easier to test / debug.
