The exporter does export matrix data (4*4 Transformation matrix) only for Skeletal animation. For object animation only exporting to trans/rot/loc is implemented.
This task implements Matrix export also for simple Object animation.

This started with a fix for an animated Object Hierarchy. Then i decided to cleanup and optimize a bit. But at the end this has become a more or less full rewrite of the Animation Exporter. All of this happened in a separate local branch and i have retained all my local commits to better see what i have done.
Brief description:
* I fixed a few issues with exporting keyframed animations of object hierarchies where the objects have parent inverse matrices which differ from the Identity matrix.
* I added the option to export sampled animations with a user defined sampling rate (new user interface option)
* I briefly tested Object Animations and Rig Animations.
What is still needed:
* Cleanup the code
* Optimize the user interface
* Do the Documentation

This is purely internal sanitizing/cleanup, no change in behavior is expected at all.
This change was also needed because we were getting short on ID flags, and
future enhancement of 'user_one' ID behavior requires two new ones.
id->flag remains for persistent data (fakeuser only, so far!), this also allows us
100% backward & forward compatibility.
New id->tag is used for most flags. Though written in .blend files, its content
is cleared at read time.
Note that .blend file version was bumped, so that we can clear runtimeflags from
old .blends, important in case we add new persistent flags in future.
Also, behavior of tags (either status ones, or whether they need to be cleared before/after use)
has been added as comments to their declaration.

The idea is pretty simple: instead of making temporary copy of all the
related custom data layers just pass the ownership from the DM to the
mesh.
This is really handy in cases when you've got DM which you need to
convert to Mesh datablock and wouldn't need that DM after conversion
anyway.
Foe example, render database conversion, exporters and even Modifier
Apply will benefit from this option.

add arguments to calculate normals when converting to bmesh:
BM_mesh_bm_from_me, DM_to_bmesh
This gives some speedup to undo (which didnt need to re-calculate vertex normals), and array modifier which doesnt need to calculate face normals at all
This means main database is no longer pollutes with
temporary scene and objects needed for freestyle
render.
Actually, there're few of separated temporary mains
now. Ideally it's better to use single one, but it's
not so much trivial to pass it to all classes. Not
so big deal actually.
Required some changes to blender kernel, to make it
possible to add object to a given main, also to
check on mesh materials for objects in given main.
This is all straightforward changes.
As an additional, solved issue with main database
being infinitely polluted with text blocks created
by create_lineset_handler function.
This fixes:
- #35003: Freestyle crashes if user expands objects in FRS1_Scene
- #35012: ctrl+f12 rendering crashes when using Freestyle
besides performance in some cases.
* DAG_scene_sort is now removed and replaced by DAG_relations_tag_update in
most cases. This will clear the dependency graph, and only rebuild it right
before it's needed again when the scene is re-evaluated.
This is done because DAG_scene_sort is slow when called many times from
python operators. Further the scene argument is not needed because most
operations can potentially affect more than the current scene.
* DAG_scene_relations_update will now rebuild the dependency graph if it's not
there yet, and DAG_scene_relations_rebuild will force a rebuild for the rare
cases that need it.
* Remove various places where ob->recalc was set manually. This should go
through DAG_id_tag_update() in nearly all cases instead since this is now
a fast operation. Also removed DAG_ids_flush_update that goes along with
such manual tagging of ob->recalc.
