Fix T63164: DNA size mismatches on 32bit, causing memory corruption and crashes.

Some alignment rules from Visual Studion on 32 bit are not taken into
account, this fixes the structs to confirm. We now have static asserts
to catch when such breakage happens in the future.

DNA: add error for DNA computed struct sizes and member offsets mismatch.

Ref T63164, there was a hidden bug like this on Windows 32 bit.

Fix T63219: error in previous commit for makesdna mismatch detection

Cleanup: remove DNA_PRIVATE_WORKSPACE hacks.

This is just not practical to do for the code as a whole, and having it as an
exception for one specific data structure is not that helpful. This has only
been in the way for me when refactoring code.

Cleanup: Fix compiler warning

Fix T63120 Select random in particle edit mode is broken

Fix coding snafu where the variable keeping track of changes only took
the state of the last element into account.

Fix T63211: Can't move camera in viewport while realtime render mode on

The issue is that Eevee directly evaluates animation on a datablock which
is a part of active dependency graph.

This is a broken logic by design and requires a complete revamp to support
more real life cases when camera is parented to a camera rig, but it is
beyond of what i can do with a simple bugfix.

Fix T61598: Python error from connect rigid body feature

needed update to 2.8

Fix T60199: Icon Viewer addon causes internal errors and slows text editor

this just removes unused icon definitions [for which no icons exist
anymore]

Cleanup: empty expression statement warning

Fix T63101: Blender crashes on adding any object to collection duplicated with added scene.

Issue was that (deep) duplication code of scene ended up leaving
children collections of new master one without any parent.

Note that even though I think that fix is OK for now, we should really
make 'deep' duplication of IDs part of the generic ID management code.
Am less and less happy with current handling of this, done half from
/editors code, half from some semi-specialized helpers from /blenkernel,
with sometimes nearly the same logic replicated several times for
slightly different needs, etc. Unfortunately this would not be a small
refactor, so it will have to wait...

Edit Mesh Selection: Clear out buffer that indicates out of bounds pixels.

This prevents the use of uninitialized buffer.
In addition, use `memset` instead of assigning in a loop.

GPencil: Handle vertex groups weights correctly

In extrude operator when the point was added, the weight data pointer was wrongly connected to old pointer.

Now, when move the data, the pointer is moved, but when a new point is added, the memory is duplicated to keep separated copies of the pointer.

This is related T62872

Thanks to @sergey for his help fixing this bug.

Cleanup: Indentation

Got broken in the previous commit somehow.

Fix memory leak in armatures with no bones

The cleanup operation was never run for such armatures.

Cleanup: Spelling

Tweak behavior of object.to_mesh()

- Passing original object with apply_modifiers=false will give a
non-modified non-deformed mesh.
The result mesh will point to datablocks from the original "domain". For
example, materials will be original.

- Passing original object with apply_modifiers=true will give a mesh which
has all modifiers applied.
The result mesh will point to datablocks from the original "domain". For
example, materials will be original.

- Passing evaluated object will ignore apply_modifiers argument, and the
result always contains all modifiers applied.
The result mesh will point to an evaluated datablocks. For example,
materials will be an evaluated IDs from the dependency graph.

Fixes T62916: Applying boolean modifier does not set material properly

Differential Revision: https://developer.blender.org/D4604

Modifiers: Proper fix for the Apply Modifier

It is up to the operator to pass valid object to the modifiers
evaluation.

Fixes T62916: Applying boolean modifier does not set materials properly

Modifiers: Use object passed to evaluation

This was wrong and violating design to force modifiers to query
evaluated objects and IDs. It is up to the caller to make sure
the object is properly evaluatable.

Effectively, reverting changes from de491abf9962 (and possibly
other related changes).

Fix T62960: Expanding/Closing Constraints/Modifiers causes re-render

Mark specific properties as no-dependency-graph tag.

This is needed to avoid a centralized Copy-on-Write tag from RNA
pointer update.
