Fix access past array boundaries

Need to resize `have_functions` arrays when adding more functions.
Not sure there is more reliable way which will prevent accidents
like this.

Gizmo: initial snap support for move

This allows the gizmo to snap to 3D view elements,
Although currently this isn't usable gizmo's that use operator redo.

Gizmo: support for cancelling move3d modal changes

Gizmo: add invoke_prepare callback

Allows gizmo groups to set values based on the gizmo about to be invoked.

Spin Tool: match dial orientation to active gizmo

Fix misleading field naming.

This is not any kind of length, it is the number of true values.

Spin Tool: option (disabled) for gizmos to follow selection

Disable since this causes multiple axis to overlap too often.
It's also glitchy since we don't have a good way to detect
changes to selection.

Correct error in last commit

Didn't account for non-identity orientation.

Spin Tool: correct the initial redo dial rotation

Merge branch 'master' into blender2.8

Multi-Objects: Selects similar face SIMFACE_COPLANAR

Unlike 2.79 I am not using the comparison type to get coplanar planes that are above/below the plane.
That seems arbritary at best, and a bit of a challenge to get it right.

Also, I'm doing some shenanigans to use a single tree to store the face direction and the distance.
Here in my tests it is working fine though.

Cleanup: naming of DRW mesh weight API

Cleanup: warnings, style

BMesh: spin option to merge first/last

For 360d revolutions this is almost always whats intended,
enable by default.

Multi-Objects: Select similar face SIMFACE_FACEMAP

Facemap is per object, so we store them in a gset per object, and only check the object
faces with its own facemaps.

Remove wrongly copy/pasted comment on object_facemap_ops.c

Curve Edit: Fix handles glitch when MSAA is enable
