Subsurf: Introduce quality option

For users it defines how accurate vertex positions are in terms
of limit surface (as in, how close the vertices locations to the
condition when they are calculated for an infinitely subdivided
mesh).

This affects things like:

- Irregular vertices (joint of 3 or more edges)
- Crease

Keep quality value low for performance.

NOTE: Going higher does not necessarily mean real improvement
in quality, ideal case might be reached well before maximum
quality of 10. Quality of 3 is a good starting point.

Internally quality is translated directly to adaptive subdivision
level.

Convert mult_face_search to use st space for better accuracy

Fix bevel problem for vertex-only cube corners.

Was introduced by code from gsoc branch that does better job
on cube corners, but shouldn't have applied to vertex-only case.

build_environment: update ilmbase and openexr to 2.3.0

Depsgraph: Build node and relations for movieclip ID for its nodes

Otherwise we get asserts when opening files with the Move Distortion node.

Make radial insert and exten work in 2d space (better accuracy)

Merge branch 'master' into blender2.8

Cleanup: avoid too close namings, prone to typo mistakes!

Fix T56224: Blender2.8 will force a quit when trying to open a scene containing clip track created by blender 2.79.

Beautiful example of typo going unoticed and firing back up in totally
unexpected place years later. Guess nobody actually duplicated a Clip
data-block before! :P

Most likely own fault, during refactor of ID copying code.

Depsgraph: Remove obscure code which was only needed for old OSD implementation

Subsurf: Remove OpenSubdiv options from modifier

There are following reasons to do so:

- The plan is to replace it with some sort of object or viewport option,
so we can apply OpenSubdiv subdivisions on top of modifier stack and
keep modifier stack purely CPU side.

This will solve issues when adding some relation in scene will force
modifier to be evaluated on CPU.

- With new upcoming OpenSubdiv based CPU modifier implementation we can
cache topology similar to what GPU side was doing, which will already
be reasonably faster.

- OpenSubdiv GPU does not work since the OpenGL version bump, and is
to be rewritten with all the adaptive refine options kept in mind.

Since OpenSubdiv GPU was already broken and was only causing object
to become invisible, there is no reason to keep having that option in
the modifier.

Fix T56290: Segfault when loading file - OpenSubdiv

Filled missing callbacks to converter.

Subsurf: Make uv boundaries easily extendible

This replaces old single toggle option to subdivide UVs with
an enum which can have more options. The usecase for this is
to be compatible with other software. But we also might choose
different subdivision type as default in the future.

DNA and underlying code supports all possible options, but
only the ones which are compatible with old subdivision code
are currently exposes.

OpenSubdiv: Add stub implementation of C-API

C-API is way smaller than the rest of the code which uses it.
So better to conditionally compile stub implementation than
to keep adding ifdef everywhere.

OpenSubdiv: Fix typo in crease comparison

Merge branch 'master' into blender2.8

Fix T56344: Crash when used Twist for Emitter type of Particles System.

That effect is NOP with emitter particles anyway...

Cleanup: Description should not end with a fullstop

OpenVDB import to padded sparse grids.
