1b18e15802 Sanitize use of BLI_iterator 
We now initialize iter.valid as true as part of the main iterator (and manually
when using via Python). And we don't even bother setting iter->current to NULL
if it's invalid. Let's stick to using iter->valid only.

f16199d479 Fix jumps-dependent-on-uninitialized-variable for iterators 
We cannot have iter->valid unitialized, but we need to be sure it is set to true on begin.
Bug found by Sergey Sharybin.

8bdc391c54 Implement a new automatic handle algorithm to produce smooth F-Curves. 
The legacy algorithm only considers two adjacent points when computing
the bezier handles, which cannot produce satisfactory results. Animators
are often forced to manually adjust all curves.

The new approach instead solves a system of equations to trace a cubic spline
with continuous second derivative through the whole segment of auto points,
delimited at ends by keyframes with handles set by other requirements.

This algorithm also adjusts Vector handles that face ordinary bezier keyframes
to achieve zero acceleration at the Vector keyframe, instead of simply pointing
it at the adjacent point.

Original idea and implementation by Benoit Bolsee <benoit.bolsee@online.be>;
code mostly rewritten to improve code clarity and extensibility.

3425732926 BLI_heap: minor changes to the API 
Recent addition of 'reinsert' didn't match logic for ghash API.

Rename to BLI_heap_node_value_update,
also add BLI_heap_insert_or_update since it's a common operation.

fdae9e1e03 BLI_array_store: correct hashing single bytes 
The single byte version of hash_data was casting from unsigned char
instead of signed.

This didn't cause any errors since the result of each aren't compared.
Even so, better keep them matching.

6dfe4cbc6b Polyfill Beautify: half-edge optimization 
Was using an edge hash for triangle -> edge lookups,
updating triangle indices for each edge-rotation.

Replace this with half-edge which can rotate edges much more simply,
writing triangles back once the solution has been calculated.

Gives ~33% speedup in own tests.

2bfa061a15 Merge branch 'master' into blender2.8 
Notes:

- Changes in paint_vertex.c were simple to merge, mainly related on passing
  evaluation context.

- Conflicts in EditDM and drawmesh.c are solved using code from blender2.8
  branch. Those areas are deprecated and not to be used in final release.

  However, it's possible that some reference code from master is lost, so
  keep attention when adding alpha support for vertex painting.
