Hi Nico,
Thanks for doing this renaming. I remember that you asked me to do this while working on cpu_power but my work has not evolved as fast as expected and as it already implies some renaming other than s/power/capacity/ i have postponed it to not make review to complex.
Nevertheless, i can manage the conflicts afterward and rebase my patches, depending of the review status

"Power" is a very bad term in the scheduler context. There are so many meanings that can be attached to it. And with the upcoming "power aware" scheduler work confusion is sure to happen.
The definition of "power" is typically the rate at which work is performed, energy is converted or electric energy is transferred. The notion of "compute capacity" is rather at odds with "power" to the point many comments in the code have to make it explicit that "capacity" is the actual intended meaning.
So let's make it clear what we man by using "capacity" in place of "power" directly in the code. That will make the introduction of actual "power consumption" concepts much clearer later on.
This is based on the latest tip tree where scheduler changes are already queued.
Note: The diffstat is not completely symetric wrt added/removed lines as some comments were reflowed.
