The point of these changes is to eventually support renumbering spans / channels on the fly as part of supporting hot pluggable spans, but this change set has the affect of reducing memory usage for small/normal installations (since arrays no longer need to be setup for spans and chans).</pre>

With DAHDI_CHUNKSIZE == 8, the practical limit is still something under 1024 channels due to the masterspan processing overhead, but this change, in conjunction with some improvements/changes there (default CHUNKSIZE something other than 8? Reduced locking?) this could be part of a solution to allow more channels on a single system without recompiling.</pre>
