There are options for the exporter that are relevant for each export, for
example the choice between Viewport or Render settings, or whether to
export the current frame or an animation. It's better to have the options
panel opened by default.
When going from EDIT to OBJECT mode, Blender updates the object data from
the edit-mode data. This took care of renaming FCurves that animate Curve
control points when control points are added/removed, but this didn't keep
the FCurve groups intact. Since the FCurve groups are tightly connected to
the Action channels, it's hard to keep the group pointers intact during
this process. Instead of making the code even more complex in an attempt to
do that, I implemented a function (`BKE_action_groups_reconstruct()`) that
rebuilds the group channel pointers.
The call to `action_groups_add_channel()` had to be removed because it
updates the the next/prev pointers of the FCurve while we're looping over
them, causing infinite loops.
- Use abbreviations min/max
this is used throughout the existing API.
- Rename use_adaptive_stepping to use_adaptive_timesteps
since this is used with timesteps_min/max it's clearer
to use matching terms.
These attributes checked for any baked / baking
since this is a common test that was performed in layout code.
Also follow our naming convention - using an 'is_/has_' prefix
in this case since "cache_baked_data" reads as if it's used to access
the baked data.
Fixed sized strings are always initialized & this is not done
elsewhere before calling BLI_path_join.
Remove since it's not needed and makes it read as if the function
might not initialize the output argument.
gpu_draw.c had generic sounding utility functions which were specific
to smoke drawing.
Split into it's own file so the functionality is clearly separated.
Allows enabling debug prints in this file easily,
differentiates it from code which has been disabled for other reasons.
Also remove unused DEBUG_TIME.
The particle system needs some tweaks so that it can be used for particles created in Mantaflow (i.e. to read both FLIP and secondary particles from Mantaflow).

A collection of smaller changes that are required in the /blender/source files. A lot of them are also due to variable renaming.

Probably the most significant changes are in smoke.c.
New functionality includes:
- support for adative time steps (substeps)
- write flow objects to grid structure so that Mantaflow can generate levelsets
- no more distinction between FLUID_3D and WTURBULENCE objects. Everthing that communicates with Mantaflow now lives in a FLUID object.

All new simulation parameters need to be registered in the RNA. Especially for liquids a lot of new ones need to be added.

Similarly to physics_fluid.c (in same directory) which handled the baking process for Elbeem, there is now physics_manta.c which handles it for Mantaflow.
There are two types of jobs: one for baking and another for freeing. The generic jobs will be used to bake / free specific parts of the simulation (e.g. bake mesh, free particles, etc.).
The jobs are only being used in the "modular" cache mode where the simulation has to be baked in parts.

Previously this limit was rather high, but with UDIMs it's fairly easy
to reach this many images. Even though this exceeds the texture limit
on most hardware as far as I can tell, it should at least not crash.
The old code uses a fixed array which overflows eventually, this fix
replaces the array with a GSet.

This was caused by a call to paint_2d_bucket_fill that I missed in the
UDIM changes.
Now, this feature does not only not crash, but it even works with tiled
images!
This makes a number of changes to the tool settings brush UI:
- All brush-related controls are now grouped together, so you can see which items are brush settings are which are not. Previously it was all jumbled together.
- The brush picker is in a separate panel, so that you can switch brushes without worrying about the settings, or vice versa.
- Custom Icon settings moved from the Display settings(now known as Cursor) to the Brushes panel.
- UnifiedPaintSettings panels are removed and the contained options are now next to their relevant setting with a globe icon toggle. This is not displayed in the header.
- 2D Falloff and Absolute Jitter toggles were changed into enums, to make it clearer what happens when they are on or off.
- Adjust Strength for Spacing option was in the Options panel in some modes, but in the Stroke panel in others. It is now always under Stroke.
- Display (now Cursor) panel was reorganized, settings renamed.
- 2-option enums are annoying as a drop-down menu, so they are now drawn with expand=True.
- Smooth Stroke and Stabilizer options in grease pencil and other paint modes are now both called "Stabilize Stroke", for consistency and clarity.
- De-duplicated some drawing code between various painting modes' brush options. I tried to keep de-duplication reasonable and easy to follow.
- A few more tweaks - see D5928 for the extensive list.
Most of the patch is written by Demeter Dzadik, with some additions by myself

- The default value of USD attributes is now only set on the first sample.
Previously this was done for every sample (so the final default was the
last value, rather than the first value).
- More use of the sparse value writer, now also for UV coordinates, mesh
normals, and curve points.
