Fix RNA crash for objects without collection properties

This would happen if you tried to access the collection property for an object
that has not being evaluated by the depsgraph.

Draw Manager: Texture space support for Curve and Metaball objects

Fix broken collada from recent merge rBb83b6afe5572ae29b4ad105dd8001c3343e2205b.

Please make minimal checks on what you do when merging!

Draw Manager: Edit Curve Mode: Fix "Not freed memory blocks"

`e_data.overlay_vert_sh` was not being freed when quitting blender.

Draw Manager: Recalculate batch of Curves, Surfaces and Texts when a property is changed

Fix crash with DispLists without vertices

Wee must return VertBuffers even when its size is zero

DNA: Add dedicated recalc flag to ID

Currently unused, but this is where LIB_TAG_ID_RECALC* flags will go.

Also modified other DNA to make pointer property being followed by pointer.
Makes it easier to keep track of alignment and extend nested structures without
ruining anything.

Eevee: Support for objects of type Curve, Surface and Text

Support for Batchs split by material for objects of type Curve, Surface, and Text

**ToDo:**
- add vertbuff for UV (what can be adapted from `dl_surf_to_renderdata`)

Depsgraph: Cleanup, use more explicit way to fill in a structure

The possible issue with just listing arguments is that it might not be clear
what particular value is used for. For example, is it a scene itself, or is
it a parent scene?

Not as if it's not very clear now, but better be explicit for the future,
and me reading code in 10 years.

Merge branch 'master' into blender2.8

Object selection: Fixing cases where old selection flag was used

Basically these operators (select grouped object hooks and object select mode/less)
were not working in 2.8.

Outliner: Fix selection drawing

Outliner was using the old selection flag to show selected objects.
So if you selected an object in the outliner it would keep "selected"
(drawn in yellow) even after you selected another object.

Depsgraph: it is still possible to have non-object to use OB_RECALC_DATA tag

Those flags are to be redone...

Comment out and tag unused bit as unused

Depsgraph: Move data update tag to object->data itself

Depsgraph / Object update: Query data update flag from data itself

RNA: Query is_updated flag from object data ID's rather than from object itself
