Checks to preserve the active spline on duplication
required an active vertex too.
Now having no active vertex doesn't prevent duplicate
from keeping the spline active.

Ref D8729
Use invert_m4_m4_safe_ortho when joining objects so zero scaled axis
doesn't cause all points to be scaled to zero.
Instead geometry is left un-scaled on degenerate axes.
Report a warning in this case since users may want to adjust the
active objects scale.
Mistake in b077de086e. I did the same fix for a few operators there,
but missed the object "Join" one.
The joining operator changes the layer content. So it must send a
notifier for that.
Before b077de086e that didn't cause a noticeable issue, because the
Outliner happened to listen to other notifiers (active/selection
changes) the operator sent and fully rebuilt its tree in response. Now
missing these notifiers can be more problematic, since we try to avoid
more rebuilds.
Added comments to the notifier types to avoid at least this pitfall.
The abbreviation 'init' is brief, unambiguous and already used
in thousands of places, also initialize is often accidentally
written with British spelling.
Using enum type itself in implementations, and uint in headers (as using
enums types in headers is a pain when enum are not defined and used in a
single same header file...).
When editing a complex curve is very annoying to have all handles at a time. Also, this is a requirement for the current GSoC Edit Grease Pencil using curves.
I have seen that this improvement can be used in any other area of blender, so I have decided to publish the option in the overlay panel..

Note this only changes cases where the variable was declared inside
the for loop. To handle it outside as well is a different challenge.

The `BKE_animsys.h` and `anim_sys.c` files already had a an "AnimData
API" section. The code in that section has now been split off, and
placed into `BKE_anim_data.h` and `anim_data.c`.
All files that used to include `BKE_animsys.h` have been adjusted to
only include the animation headers they need (sometimes none).
No functional changes.
The original code has two logics, extrude the end points or duplicate points (making new splines).
Now all the logic has been redone by extruding contiguous selected segments.

Currently, this change does not bring functional changes.
But it is necessary to extend the use of the snap system for gizmos,
since, after a Undo, the `depsgraph` pointed by the `snap_context`
has its memory invalidated.

The old convention was easy to confuse with ScrArea.

This is mostly a batch rename with some manual fixing. Only single word
variable names are changed, no prefixed/suffixed names.
Brecht van Lommel and Campbell Barton both gave me a green light for
this convention change.
Also ran clan clang format on affected files.
into account for duplicating actions
Previously actions remained linked after duplication, now this is based
on the User Preferences (PreferencesEdit.use_duplicate_action).
note: default is ON here, so this changes default behavior of separate
operators.
First intuition was to respect _all_ preferences here (e.g. also
duplicating materials if chosen in the User Preferences) but after
consideration this is probably not what the User would expect from such
'modeling' opertions (e.g. separate by loose parts resulting in possibly
many duplicate materials)

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.
Particularly noticeable when vertex painting with a subsurf modifier.
In some cases every sculpt or paint stroke step would evaluate the dependency
graph. This should only happen for redraws. Now more selectively choose if the
dependency graph should be evaluated to initialize the view context. Doing it
in the view context evaluation is somewhat hidden, now it's more explicit.

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.
