Some of these API's can have 3D versions, explicitly name them 2D.

- 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.

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.

Improves performance for high poly meshes,
~70% faster for decimate, only ~10% for beautify.

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.

Only lock tri's facing different directions.
Needed because scanfill creates zero area faces.

mistakenly considering the state as degenerated"
This reverts commit a8f11f5422afa01608817755eea310e987f896be.
Result is no longer symmetrical, will investigate a different fix.

|
|
Some error checks weren't being done in both directions
when calculating the best split direction for a quad.
|
|
Needed for 3D iterative edge-rotation to avoid flipping when projected
from different angles,
but could keep zero area faces in 2D polygons.

Another case of float imprecision leading to endless loop. INcreasing a bit 'noise threashold' seems to work OK.
Not a regression, but might be nice to have in 2.78a.

rpecision issue.
Only recompute if cost is below -FLT_EPSILON, we can get cases where both cases generate
very tiny negative costs (see 'Cylinder.004' mesh in .blend attached to report).

MSVC doesn't like caling macro argument f when using float values
in the macro, it simply replaces the f in the float value with the
argument..
CMake compilation still fails because of 77785ce70807, numpy is never
getting unpacked.

Triangulate with beautify caused a bug when there were existing edges
could make the bmesh-operator return an invalid face-map.
Now the beauty is calculated on the 2d-tri's resulting from polyfill,
its simpler and faster.
