This change ensures that operators which needs access to evaluated data
first makes sure there is a dependency graph.
Other accesses to the dependency graph made it more explicit about
whether they just need a valid dependency graph pointer or whether they
expect the graph to be already evaluated.
This replaces OPTYPE_USE_EVAL_DATA which is now removed.
Some general rules about usage of accessors:
- Drawing is expected to happen from a fully evaluated dependency graph.
There is now a function to access it, which will in the future control
that dependency graph is actually evaluated.
This check is not yet done because there are some things to be taken
care about first: for example, post-update hooks might leave scene in
a state where something is still tagged for update.
- All operators which needs to access evaluated state must use
CTX_data_ensure_evaluated_depsgraph().
This function replaces OPTYPE_USE_EVAL_DATA.
The call is generally to be done in the very beginning of the
operator, prior other logic (unless this is some comprehensive
operator which might or might not need access to an evaluated state).
This call is never to be used from a loop.
If some utility function requires evaluated state of dependency graph
the graph is to be passed as an explicit argument. This way it is
clear that no evaluation happens in a loop or something like this.
- All cases which needs to know dependency graph pointer, but which
doesn't want to actually evaluate it can use old-style function
CTX_data_depsgraph_pointer(), assuming that underlying code will
ensure dependency graph is evaluated prior to accessing it.
- The new functions are replacing OPTYPE_USE_EVAL_DATA, so now it is
explicit and local about where dependency graph is being ensured.
This commit also contains some fixes of wrong usage of evaluation
functions on original objects. Ideally should be split out, but in
reality with all the APIs being renamed is quite tricky.
Fixes T67454: Blender crash on rapid undo and select
Speculation here is that sometimes undo and selection operators are
sometimes handled in the same event loop iteration, which leaves
non-evaluated dependency graph.

Use explicit boolean flag to indicate whether flush to original data
is needed or not. Makes it possible to avoid confusion on whether an
evaluated or any depsgraph can be passed to the API.
Allows to remove depsgraph from bAnimContext as well.

If one of the objects had invalid selected edges, it would lead to a
crash since none of the for loops were checking for whether the edge
slide data is valid.
We could refactor the macros to create a new
FOREACH_TRANS_DATA_CONTAINER_WITH_DATA
However we are too close to 2.80 final release so we manually skip them
for now.
Note: TRANS_DATA_CONTAINER_FIRST_OK cannot be used either for the same
reason.

This reverts commit 36faf739a7.
Somewhat annoying but this change had some unforeseen consequences,
which lead to an actual bug.
Since this change was not sufficient to get original report fixed
is easier to simply revert for now.

Allows it to be preserved during copy-on-write update when on-geometry

This option can not be supported by a new granular dependency graph,

It was always doing full update ever since initial commit of new dependency
graph which we are using here in the studio for the past years and lack of

Actually, when you press G/R/S in Draw mode, the transformations can be done, but this is annoying in draw mode and must be captured an cancel.

User counting now happens before init() and after free() methods, so that
the ID users are in a valid state when Python might modify them. ID user
counting was moved into node.c and simplified.
Patch by Miguel with further refactoring by Brecht. Ref D4370.
Convention was not to but after discussion on 918941483f we agree its
best to change the convention.
Names now mostly follow RNA.
Some exceptions:
- Use 'nodetrees' instead of 'nodegroups'
since the struct is called NodeTree.
- Use 'gpencils' instead of 'grease_pencil'
since 'gpencil' is a common abbreviation in the C code.
Other exceptions:
- Leave 'wm' as it's a list of one.
- Leave 'ipo' as is for versioning.
Was caused by another fix in the area, and root to the wrong though that
transformation is only initialized from a fully evaluated dependency graph.
The latter one is not a case when changing transformation mode.
Solved by copying transform to an evaluated object.
Transfomr init code called just after duplication (presumably before
regular depsgraph update is executed) would erase new objects'
transflags.
This is more like a hack than a real fix, but since that transform piece
of code is already a hack... Other solution would have been to force DEG
to run after object duplication, think it's better to go with that
solution for now.
Not to mention to fact that dupli flags are put into transflag... ;)
