python: Add utility function to override config parameters
Add a utility method, SimObject.apply_config that can be used to
implement SimObject param overrides from the command line. This
function provides safe and convenient semantics for CLI assignment:
* The override expression is evaluated in a restricted environment. The
only global variables are the child objects and params from the root
object.
* Only params can be overridden. For example, calling methods or setting
attributes on SimObjects isn't possible.
* Vectors use non-standard list semantics which enable something similar
to glob expansion on the shell. For example, setting:
root.system.cpu[0:2].numThreads = 2
will override numThreads for cpu 0 and 1 and:
root.system.cpus[0,2].numThreads = 2
sets it for cpus 0 and 2.
The intention is that the helper method is called to override default
values before calling m5.instantiate.
