Dalai Felinto 394c5318c6 Bake-API: reduce memory footprint when baking more than one object (Fix T41092)
Combine all the highpoly pixel arrays into a single array with a lookup
object_id for each of the highpoly objects.

Note: This changes the Bake API, external engines should refer to the
bake_api.c for the latest API.

Many thanks for Sergey Sharybin for the complete review, changes
suggestion and feedback. (you rock!)
