[PATCH v6 0/4] Add APIs for configurable power options

[Kevin Laatz <kevin.laatz@intel.com>]

The power library contains some variables which are currently set by
defines, hard-coded values or set using sysfs values. In order to
configure these, code changes and recompiles are required, making
configuring these variables tedious.

This patchset introduces some new get/set APIs which allow users and
applications to configure there settings to suit their use-cases.
In addition, CLI options have been added to l3fwd_power to demonstrate
how an application could use these APIs to expose the options to users
without needing code changes to configure them.
