[refactor] convert area to new errors, create
Convert area/area_linux to new error handler. Implement #31 for area. Checkpatch area Note that area_linux is still using a dynamic data structure no matter what: a bitmask to the set of authorized nodes. The conversion to aml_bitmap wouldn't help as there's no default value available for all nodes on that type (similar to numa_all_nodes_ptr).
