Regression in recent undo system changes,
This caused T55048.
When each mode had its own undo stack it was important
to initialize it when entering edit-mode.
- Use a single undo history for all operations.
- UndoType's are registered and poll the context to check if they
should be used when performing an undo push.
- Mode switching is used to ensure the state is correct before
undo data is restored.
- Some undo types accumulate changes (image & text editing)
others store the state multiple times (with de-duplication).
This is supported by checking UndoStack.mode `ACCUMULATE` / `STORE`.
- Each undo step stores ID datablocks they use with utilities to help
manage restoring correct ID's.
Needed since global undo is now mixed with other modes undo.
- Currently performs each undo step when going up/down history
Previously this wasn't done, making history fail in some cases.
This can be optimized to skip some combinations of undo steps.
grease-pencil is an exception which has not been updated
since it integrates undo into the draw-session.
See D3113
Now repeating the operator will use the previously chosen offset, either with
the modal operator or typed in. The modal operator will still start at zero.
Vertex group remapping utility function,
now shared between object join and array modifier cap-ends.
Weights which don't exist are removed.

When you were using autosmooth to generate some custom normals, and
created empty custom loop normal data, you would go back to an 'all
smooth' shading, cancelling some sharp edges generated by the mesh's
smooth threshold.
Now we will first tag such edges as sharp, such that shading remains the
same. This is not crucial in current master, but it is for clnors
editing gsoc branch!
Optionally don't remap indices for objects.
Checking all objects parent's would reference a freed pointer
while freeing all objects.
In the case of dynamic topology there is no use in keeping track
of hook/vertex-parent indices.
Also disable this when creating meshes for undo storage
since adding an undo step shouldn't be modifying other objects.
- When returning the number of items in a collection use BLI_*_len()
- Keep _size() for size in bytes.
- Keep _count() for data structures that don't store length
(hint this isn't a simple getter).
See P611 to apply instead of manually resolving conflicts.
Patch from Richard Erhardt, with some additions & modifications.
Changes bevel profile shape parameter so that can get arbitrarily
near square profile as parameter -> 1.
Adds code to make profile=0 case work, at least for cube corners,
so changed hard min of profile parameter to 0 from 0.15.
Pixel size was not initial early enough. For first time this was not a problem
because the bevel amount starts at 0 then, and after the mouse moves the pixel
size is initialized. For the second time the bevel amount starts at a non-zero
value, and it failed then.
This makes code closer to id_override/assent-engine ones, which
introduce a new type of linked data, and hence reserve
ID_IS_LINKED_DATABLOCK to real linked datablocks.
