0d7d317755 BMesh: add checks for duplicates in a face 
These could go un-noticed, causing errors later on.

d7723df846 BMesh: partial-connection could make duplicate edges 
Avoiding to make duplicate edges is too involved, do a remove-duplicates pass at the end instead.

88191f7fa3 BMesh: support connecting single-edge island links 
Handle these cases by temporarily disconnecting the single links to ensure isolated islands,
then link back up after.

8cd7b42877 BMesh: Add option to use BMesh boolean modifier 
This uses a bmesh-intersection, BLI_kdtree and watertight intersections to perform boolean operations.

For now keep both BMesh and Carve booleans usable at once for testing & bug reports,
however we plan to phase out Carve by next release.

d70e0b6654 BMesh: Boolean as an edit-mode tool 
Works much the same as intersect operator,
expose as a new operator since for users its quite different.

Access from face menu.

Internally, this adds boolean args to BM_mesh_intersect function.

3c6709a63c Fix T37879: Default UV generation for mesh primitives. 
Adds default-generated UVs to mesh primitives (cone, cylinder, icosphere, uvsphere, cube, circle, grid)
when they are added to the scene, since some of them can be pretty awkward to unwrap manually.

Original patch: Liam Mitchell (CommanderCorianderSalamander).
Main review work: Campbell Barton (campbellbarton).
Finalization, fixes and cleanup: Bastien Montagne (mont29).

410ca0ed92 Recent change to bmesh_jekv caused assert

29d9140fce Fix T46804: Crash using triangulate modifier on a specific mesh. 
Issues was again the ugly hack of swapping last generated tri with original face
we use in BMesh triangulate code - here it could lead in some rare case to have
invalid face pointer in doubles list.

8bdb884289 Fix related to T46804 - BMesh validate code would use invalid pointers after checking them! 
Note that this does not fix the issue reported in T46804, juts makes it crash later down in code...

3863660c37 Fix face creation using incorrect loop-custom-data 
Custom-data on newly created face data was often rotated.

Now the API doesn't copy data from adjacent loops when creating faces.
Most functions were already overwriting this anyway.

Since such decisions are better made at a higher level, now it's the responsibility of the caller.

56bcda8bc6 Fix BMesh selection flushing w/ mixed modes 
Fix for T46494 wasn't working properly when de-selecting faces,
adjacent faces would remain selected but have unselected edges.

Logic here is admittedly rather fragile since it relies on both
selection functions and flushing afterwards.
