can_suspend_to_{x}

[Richard Hughes]

In the spirit of making everything consistent [1] I think the:

  power_management.can_suspend_to_disk
  power_management.can_suspend_to_ram

keys should be:

  power_management.can_hibernate
  power_management.can_suspend

As we already call the methods Suspend() and Hibernate() and I'm trying
to make this a little more sane with all the power stuff for all the
overlapping nomenclature. I'm sending similar emails to other projects
as I want to make this as standardised as possible.

I figure getting the same names so it all makes sense when we document
it, is worth the short term pain of breaking (undocumented?) API.

What do you think?

Richard.
