Sculpt: Fix undo not working for multires

Subdiv: CCG, implement averaging along edges and corners

Makes it so smooth brush works properly, without causing grids
to become disconnected from each other.

This need to optimize the code for brush, to only average edges
and vertices which are adjacent to modified faces.

Subdiv: CCG, store vertex adjacency information

Similar to previous commit, but for vertices.

Subdiv: CCG, store edge adjacency information

This information is stored for each non-loose edge.

For each of such edge we store:

- List of CCG faces it is adjacent to.

This way we can easily check whether it is adjacent to
any face which is tagged for update or so.

- List of boundary elements from adjacent grids.

This allows to traverse along the edge and average all
adjacent grids.

OpenSubdiv: Add extra base level queries to topology refiner

Subdiv: CCG, fix memory leak

Forgot to free memory used by grid to face mapping array.

Subdiv: CCG, fix crash going from sculpt to edit mode

Was happening for "new" objects, which did not have MDisps
allocated yet.

Subdiv: CCG, localize Mesh usage even more

Subdiv: CCG, go away from Mesh

Use topology refiner where possible, which will make code more
portable and less dependent on all the possibly outdated pointers.

Merge branch 'master' into blender2.8

Sculpt: Fix memory leak in undo system

Was not freeing undo nodes themselves.

GP: Remove Copy & Paste buttons

GP: Fix problem with mode opening 2D Animation template

The grease pencil does not need a toggle of mode.

This fix also the problem when open grease pencil files that did not keep the mode saved.

GP: Fix falloff curve using 2D animation template

GP: Fix template name typo error

GP: Fix Alt+S problem with multiframe edition

The stroke must not be recalc, because the number of points does not change,so the triangulation of fill is the same.

Cleanup: move DerivedMesh wrappers for modifiers further down the hierarchy

The main goal of this patch is to cleanup the interface of every modifier. More specifically the interface of modifiers should be DerivedMesh-free.
Internally some modifiers still use DerivedMesh. However I think it is better when the wrappers are in the modifiers so that higher level functions can use the simplified interface.

This patch removes the applyModifier_DM and applyModifierEM_DM functions. In a previous patch (rB3614d9d) the other functions that used DerivedMesh have been removed.

GP: Add keymap 1 and 2 for select mode

GP: New select mode

Now it's possible select points or strokes

Put the Radius property of Curve points under shape key control.

Since shape keys are stored as raw floating point data, this
unfortunately requires changes to all code that works with it.

An additional complication is that bezier and nurbs control
points have different entry size, and can be mixed in the same
object (and hence shape key buffer).

Shape key entries are changed from:

bezier: float v1[3], v2[3], v3[3], tilt, pad, pad;
nurbs: float vec[3], tilt;

To:

bezier: float v1[3], v2[3], v3[3], tilt, radius, pad;
nurbs: float vec[3], tilt, radius, pad;

The official shape key element size is changed to 3 floats,
with 4 elements for bezier nodes, and 2 for nurbs. This also
means that the element count is not equal to the vertex count
anymore.

While searching for all curve Shape Key code, I also found that
BKE_curve_transform_ex and BKE_curve_translate were broken. This
can be seen by trying to change the Origin of a Curve with keys.
