Sculpt: Implement plane deformation falloff for Grab

The plane deformation falloff was introduced in the first version of the
cloth brush, but due to the lack of all the new features and fixes in the
solver it was causing a lot of artifacts for deformation brushes. In
order to avoid that, the cloth brush was always using radial falloff for
the grab brush.

Now the plane falloff is properly implemented using the deformation
constraints.

Sculpt: Option to limit the action of line gestures to the segment

This adds a tool property for sculpt line gesture tools (line and
project) to limits its effect to the segment of the gesture instead of
using the infinite line to bisect the mesh in two parts.

To achieve that, the line gesture now has two extra side planes that can
be enabled/disabled for getting the nodes from the PBVH and to test the
vertices.

Sculpt: Face Set Edit delete Geometry operation

This adds an operation mode to the Face Set Edit tool which deletes the
geometry of a Face Set by clicking on it.
The operator also checks for the mesh having a single Face Set to avoid
deleting the entire object by accident.
This is also disabled for Multires to avoid modifying the limit surface
without control (it is not an important limitation as base meshes for
multires are usually final, but maybe it can be supported in the future).

Merge branch 'master' into cycles_procedural_api

fix up ConvertNode before merge

Fixed broken customdata interpolation in dyntopo collapse.
Also added support for uvs to dyntopo gpu buffer building code.

Added support for customdata interpolation to dyntopo.
It seems fast enough for simple cases, I make no promises that it
will be fast in crazy cases lots if there's lots of vgroup layers.

Note I still need to interface properly with the sculpt colors code.

Fix bugs in last commit.

Refactored sculpt code to use a new type, SculptVertRef, that replaces
much of the usage of integer indices. Meshes and grids simply store the
index here, but bmesh stores a pointer to a BMVert. This greatly speeds
up DynTopo by reducing the need to maintain flat pointer arrays in bmesh.

To prevent the accidental casting of ScuptVertexRef to indices and vice
versa SculptVertRef is defined as a struct:

typedef struct {intptr_t i} SculptVertRef;

There are also two functions to convert flat index indices to
SculptVertRefs and back:

ScultpVertRef BKE_pbvh_table_index_to_vertex(PBVH *pbvh, int index);
int BKE_pbvh_vertex_index_to_table(PBVH *pbvh, SculptVertRef *ref);

Note that these functions require the aforementioned maintanance of
flat pointer arrays in bmesh, so make sure to call
SCULPT_ensure_vertex_random_access().

UI Code Quality: Cleanup ui_but_update_from_old_block

This commit contains some improvements to this function to make this
function more purposeful and readable.
- Split updating information of the old button to a new function.
- Remove some 7 year old code disabled with `#if 0`.
- Add comments explaining some of the less obvious aspects.
