This patchset adds the library, along with the new APIs, edits to EAL functions to call the API instead of implementing their own, and changes to the dlb2 driver to call the API. The new APIs work similar to existing functions in EAL, however instead of filling a core array like this: [1, -1, -1, 2, 3] (a non -1 refers to an 'active core' at that index) It fills it like this: [0, 3, 4] (with the value at each index being an 'active core'). The new APIs will also return the number of cores contained in the passed corelist/coremask, so in the above example, 3 would be returned. Planned future work for the library contains more parsing functions such as a "core string parser" which would take a string and return whether its a corelist or coremask based on heuristics. This could then be passed into the appropriate function. There are also several example applications that implement their own version of a corelist/coremask parser, so the plan is to rework those in future versions of this patch.
