This patch simplifies the curve object to mesh conversion
used by the object convert operator and exporters.
The existing code had a convoluted model of ownership, and did quite
a bit of unnecessary work. It also assumed that curve objects always
evaluated to a mesh, which is not the case anymore.
Now the code checks if the object it receives is evaluated. If so,
it can simply return a copy of the evaluated mesh (or convert the
evaluated curve wire edges to a mesh if there was no evaluated mesh).
If the object isn't evaluated, it uses a temporary copy of the object
with modifiers removed to create the mesh in the same way.
This follows up on the recent changes to curve evaluation,
namely that the result is always either a mesh or a wire curve.

With this commit, curve objects support the geometry nodes modifier.
Curves objects now evaluate to `CurveEval` unless there was a previous
implicit conversion (tessellating modifiers, mesh modifiers, or the
settings in the curve "Geometry" panel). In the new code, curves are
only considered to be the wire edges-- any generated surface is a mesh
instead, stored in the evaluated geometry set.
The consolidation of concepts mentioned above allows remove a lot of
code that had to do with maintaining the `DispList` type temporarily
for modifiers and rendering. Instead, render engines see a separate
object for the mesh from the mesh geometry component, and when the
curve object evaluates to a curve, the `CurveEval` is always used for
drawing wire edges.
However, currently the `DispList` type is still maintained and used as
an intermediate step in implicit mesh conversion. In the future, more
uses of it could be changed to use `CurveEval` and `Mesh` instead.
This is mostly not changed behavior, it is just a formalization of
existing logic after recent fixes for 2.8 versions last year and two
years ago. Also, in the future more functionality can be converted
to nodes, removing cases of implicit conversions. For more discussion
on that topic, see T89676.
The `use_fill_deform` option is removed. It has not worked properly
since 2.62, and the choice for filling a curve before or after
deformation will work much better and be clearer with a node system.
Applying the geometry nodes modifier to generate a curve is not
implemented with this commit, so applying the modifier won't work
at all. This is a separate technical challenge, and should be solved
in a separate step.

`BKE_displist_make_curveTypes` had a `for_orco` argument that was
always false in calls to the function. Removing it allows the curve
displist and modifier evaluation code to become simpler. There are
some related cleanups in rBdf4299465279 and rB93aecd2b8107.
Some of the comments referenced code that was no longer there, or even
defines that were removed. Other comments were more confusing and
vague than helpful. Also adjust formatting in a few cases.
This was added in rB93aeb6b318a7, last changed in rB8f0a44a5d55d,
and removed in rB51b796ff1528. I assume it was a way for curves to
have split edges at corners. As far as I can tell it only ever worked
in Blender Internal, and that has been gone for years.
Another possible route here would be restoring this functionality,
but it's generally preferrable to reduce complexity in this
area of curve code than adding it back, especially in the context
of other improvements planned related to curves in geometry nodes.

This patch adds a to_curve method to the Object ID. This method is
analogous to the to_mesh method. The method can operate on curve and
text objects. For text objects, the text is converted into a 3D Curve ID
and that curve is returned. For curve objects, if apply_modifiers is
true, the spline deform modifiers will be applied and a Curve ID with
the result will be returned, otherwise a copy of the curve will be
returned.
The goal of this addition is to allow the developer to access the splines
of text objects and to get the result of modifier applications which was
otherwise not possible.

A few related improvements to the three functions:
- Reduce variable scope
- Use for loops instead of while loops
- Use const, bool instead of int
- Generally make logic easier to read
This replaces header include guards with `#pragma once`.
A couple of include guards are not removed yet (e.g. `__RNA_TYPES_H__`),
because they are used in other places.
This patch has been generated by P1561 followed by `make format`.

This is old logic that no longer makes sense in the new depsgraph, and causes
issues when multiple threads try to modify the same bevel object.
Differential Revision: https://developer.blender.org/D4913
Curve function had two arguments:
- for_render, which was originally supposed to be used to control
whether viewport or render visibility for modifiers is to be
used.
- use_render_resolution, which sounds like it is supposed to control
whether viewport or render resolution for curves is to be used.
What is totally confusing is that those arguments were used
interchangeably: sometimes use_render_resolution would control
modifiers visibility.
This commit makes it so there is one single argument for this.

This was caused by curves pointing to each other
creating a cyclic dependency.
While the dependency graph detects this, generating a mesh for render
recursively generates data which cashes in this case.
Add in a check to detect cyclic links.
Note, this bug exists in 2.7x too - but only crashes on render
since 2.7x didn't use 'for_render' when converting data.
BF-admins agree to remove header information that isn't useful,
to reduce noise.

This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.
See P901 for script to perform these edits.
Not exactly sure why we did not have cached displist for bevel object
here... But anyway, that conversion operation should really happen
outside of depsgraph evaluation area, so makes sense to do it as when
generating geometry for rendering, imho. Also solves issues like loosing
hidden parts of the curve/surface, etc. Still using viewport resolution
for curves, though.
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.

2.8x branch added bContext arg in many places,
pass eval-context instead since its not simple to reason about what
what nested functions do when they can access and change almost anything.
Also use const to prevent unexpected modifications.
This fixes crash loading files with shadows,
since off-screen buffers use a NULL context for rendering.
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.
Summary:
Made objects update happening from multiple threads. It is a task-based
scheduling system which uses current dependency graph for spawning new
tasks. This means threading happens on object level, but the system is
flexible enough for higher granularity.
Technical details:
- Uses task scheduler which was recently committed to trunk
(that one which Brecht ported from Cycles).
- Added two utility functions to dependency graph:
* DAG_threaded_update_begin, which is called to initialize threaded
objects update. It will also schedule root DAG node to the queue,
hence starting evaluation process.
Initialization will calculate how much parents are to be evaluation
before current DAG node can be scheduled. This value is used by task
threads for faster detecting which nodes might be scheduled.
* DAG_threaded_update_handle_node_updated which is called from task
thread function when node was fully handled.
This function decreases num_pending_parents of node children and
schedules children with zero valency.
As it might have become clear, task thread receives DAG nodes and
decides which callback to call for it.
Currently only BKE_object_handle_update is called for object nodes.
In the future it'll call node->callback() from Ali's new DAG.
- This required adding some workarounds to the render pipeline.
Mainly to stop using get_object_dm() from modifiers' apply callback.
Such a call was only a workaround for dependency graph glitch when
rendering scene with, say, boolean modifiers before displaying
this scene.
Such change moves workaround from one place to another, so overall
hackentropy remains the same.
- Added paradigm of EvaluaitonContext. Currently it's more like just a
more reliable replacement for G.is_rendering which fails in some
circumstances.
Future idea of this context is to also store all the local data needed
for objects evaluation such as local time, Copy-on-Write data and so.
There're two types of EvaluationContext:
* Context used for viewport updated and owned by Main. In the future
this context might be easily moved to Window or Screen to allo
per-window/per-screen local time.
* Context used by render engines to evaluate objects for render purposes.
Render engine is an owner of this context.
This context is passed to all object update routines.

That ended up in tricky code trying to mimic depsgraph
branch behavior API-wise preserving texspace and bound
box calculation compatible with previous releases.
So for now bring cu->disp back to the trunk but keep
texpsace and boundbox APIs the same as in the branch.
This keeps texpsapce and boundbox behavior fully compatible
with previous releases and still makes API the same as
for meshes.
