ee5f32a382 sim: Add function that returns all variables in a MathExpr
This changes adds support for retrieving all variables in a math
expression. The added function can be called in all valid expressions
and will return the variables in a vector of strings.

1088f0c4ac misc: Rename misc.(hh|cc) to logging.(hh|cc)
These files aren't a collection of miscellaneous stuff, they're the
definition of the Logger interface, and a few utility macros for
calling into that interface (panic, warn, etc.).

7cfb59d6e5 sim: Adding support for power models
This patch adds some basic support for power models in gem5.

The power interface is defined so it can interact with thermal
models as well. It implements a simple power evaluator that
can be used for simple power models that express power in the
form of a math expression. These expressions can use stats
within the same SimObject (or down its hierarchy) and some
magic variables such as "temp" for temperature.
In future patches we will extend this functionality to allow
slightly more complex expressions.

The model allows it to be extended to use other kinds of models.

Finally, the thermal model is updated to use the power usage as input.
