Liblink specific ID type function was so far running a loop over all IDs of relevant type, unlike almost any other 'ID-callback-like' functions in Blender, which usually let the looping controll to calling code. The latter approach is more convinient when one want to add generic (i.e. type-agnostic) code, since it typically only has to change code in one place (caller function) instead of tens of places (all the callback functions). This commit also changes/sanitizes a few things that had nothing to do in main liblink code, like mesh conversion from tessfaces to polys (which can be done in after-linking versionning code), or scenes' cycles detection/check regarding background 'set' scenes.
