The modifier performed the 'bind' operation not in the bind operator,
but delayed in the mesh evaluation. This saved the result in a CoW copy
instead of in the actual modifier data. The binding operator now follows
the same approach as Mesh Deform: it forces the modifiers to run on the
real (non-CoW) data, making it possible for the modifier to store the
binding data.
This commit also ports the usage of DerivedMesh to Mesh.
The contents of the ModifierEvalContext struct are constant while iterating
over the modifier stack. The struct thus should be only created once, outside
any loop over the modifiers.
Makes the follow changes:
- Add new `deform*` and `apply*` function pointers to `ModifierTypeInfo` that take `Mesh`, and rename the old functions to indicate that they take `DerivedMesh`. These new functions are currently set to `NULL` for all modifiers.
- Add wrapper `modifier_deform*` and `modifier_apply*` functions in two variants: one that works with `Mesh` and the other which works with `DerivedMesh` that is named with `*_DM_depercated`. These functions check which type of data the modifier supports and converts if necessary
- Update the rest of Blender to be aware and make use of these new functions
The goal of these changes is to make it possible to port to using `Mesh` incrementally without ever needing to enter into a state where modifiers don't work. After everything has been ported over the old functions and wrappers could be removed.

The depsgraph was always created within a fixed evaluation context. Passing
both risks the depsgraph and evaluation context not matching, and it
complicates the Python API where we'd have to expose both which is not so
easy to understand.
This also removes the global evaluation context in main, which assumed there
to be a single active scene and view layer.

- Wasn't clear which functions handle edit-bones.
- Mixed both ebone and edit_bone in names.
- Didn't use ED_armature_* prefix for public API.
See P655 to apply to branches.
- Read-only access can often use EvaluationContext.object_mode
- Write access to go to WorkSpace.object_mode.
- Some TODO's remain (marked as "TODO/OBMODE")
- Add-ons will need updating
(context.active_object.mode -> context.workspace.object_mode)
- There will be small/medium issues that still need resolving
this does work on a basic level though.
See D3037
The RenderResult struct still has a listbase of RenderLayer, but that's ok
since this is strictly for rendering.
* Subversion bump (to 2.80.2)
* DNA low level doversion (renames) - only for .blend created since 2.80 started
Note: We can't use DNA_struct_elem_find or get file version in init_structDNA,
so we are manually iterating over the array of the SDNA elements instead.
Note 2: This doversion change with renames can be reverted in a few months. But
so far it's required for 2.8 files created between October 2016 and now.

This makes code closer to id_override/assent-engine ones, which
introduce a new type of linked data, and hence reserve
ID_IS_LINKED_DATABLOCK to real linked datablocks.
Note that some little parts of code have been dissabled because eval_ctx
was not available there. This should be resolved once DerivedMesh is
replaced.
The custom poll function for surfacedeform_bind seems to have caused
issues when calling it from Python. Fixed by using the generic modifier
poll function, and setting the button to be active or not in the
Python UI code instead. (there might be a better way, but for now this
works fine)
Design Documents

User Commit Log
---------------
* New Layer and Collection system to replace render layers and viewport layers.
* A layer is a set of collections of objects (and their drawing options) required for specific tasks.
* A collection is a set of objects, equivalent of the old layers in Blender. A collection can be shared across multiple layers.
* All Scenes have a master collection that all other collections are children of.
* New collection "context" tab (in Properties Editor)
* New temporary viewport "collections" panel to control per-collection
visibility
Missing User Features
---------------------
* Collection "Filter"
Option to add objects based on their names
* Collection Manager operators
The existing buttons are placeholders
* Collection Manager drawing
The editor main region is empty
* Collection Override
* Per-Collection engine settings
This will come as a separate commit, as part of the clay-engine branch
Dev Commit Log
--------------
* New DNA file (DNA_layer_types.h) with the new structs
We are replacing Base by a new extended Base while keeping it backward
compatible with some legacy settings (i.e., lay, flag_legacy).
Renamed all Base to BaseLegacy to make it clear the areas of code that
still need to be converted
Note: manual changes were required on - deg_builder_nodes.h, rna_object.c, KX_Light.cpp
* Unittesting for main syncronization requirements
- read, write, add/copy/remove objects, copy scene, collection
link/unlinking, context)
* New Editor: Collection Manager
Based on patch by Julian Eisel
This is extracted from the layer-manager branch. With the following changes:
- Renamed references of layer manager to collections manager
- I doesn't include the editors/space_collections/ draw and util files
- The drawing code itself will be implemented separately by Julian
* Base / Object:
A little note about them. Original Blender code would try to keep them
in sync through the code, juggling flags back and forth. This will now
be handled by Depsgraph, keeping Object and Bases more separated
throughout the non-rendering code.
Scene.base is being cleared in doversion, and the old viewport drawing
code was poorly converted to use the new bases while the new viewport
code doesn't get merged and replace the old one.

Idea is to replace hard-to-track (id->lib != NULL) 'is linked datablock' check everywhere in Blender
by a macro doing the same thing. This will allow to easily spot those checks in future, and more importantly,
to easily change it (see work done in asset-engine branch).
Note: did not touch to readfile.c, since there most of the time 'id->lib' check actually concerns the pointer,
and not a check whether ID is linked or not. Will have a closer look at it later.

It's needed especially for the menu entry "recover auto save" where you'd like to have the files sorted by date most of the time but it could be useful in other places too.
There should be no functional change in other areas, I just added the missing parameter (FILE_SORT_ALPHA).
Was a request from @sebastian_k at #BCon13, so at least one guy needs it ;)

This calls are not strictly speaking needed for the old dependency graph, but
due to more granular nature of upcoming depsgraph more actions requires update
of relations of IDs.
On the one hand this extra tags could be wrapped with if() statements, but on
the other hand it makes sense to keep tag in sync so it's clear if some issue
is caused by missing/extra tag or by depsgraph itself.
