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.

Use Python3.5's unpacking generalizations

Mistake in last commit

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.

Correct error in recent commit w/ hole-filling

edge-groups weren't being sorted with 2d-coords applied.

Fix T46951: GLSL draw mode missing some textures.

BMesh: hole support for intersect tool

Support cutting many outlines into a single face (creating edges between isolated regions).

BMesh: Add BM_face_kill_loose

Removes edges/verts that become unused.

Memutil: remove some unused code.

IK Solver: remove unused and outdated test code.

Moto: remove some unused code.

Math Lib: 2d ray-segment intersection function

IK Solver: replace TNT math library with Eigen.

Performance is about the same or slightly better for typical IK chains.
In extreme cases with many bones and multiple targets, of which some are
unreachable, I've seen 2x speedups.

IK solver: replace Moto math library with Eigen.

MSVC 2015 fix, /WX warnings as errors is to restrictive for msvc 2015 currently for bmesh

MSVC 2015 fix hack around internal compiler crash on openmp atomic

Eigen3 bug report: http://eigen.tuxfamily.org/bz/show_bug.cgi?id=1131

Fix for mistake in intersect duplicate list check

In practice this hardly ever happened.

BMesh: minor optimization for intersect

Avoid double lookup on insertion ghash

Update Eigen to version 3.2.7

The main purpose of this is to get MSVC 2015 fixes

Begin to add some MSVC 2015 support
