Works by using multiple selection modes.
So, if you select vert then face, only clnor linked with
both vert and face will be edited.

Has some issues though, as vert + edge selection can
be associated to either of 2 clnors. Need to fix.

Added invalidate for transform ops.

Can now keep clnors when transform ops are applied. As now invalidation for each function is harder to keep track of, Added a function which rebuilds all the lnor spaces in the mesh when BM_lnorspace_rebuild is called to detect if any unmarked spaces are rebuilt.

Added normals to follow mouse location.

Now M key can be used after ALT - L to have clnors point to mouse location.

Added point to origin and LMB click

Fixed issues with Point Normals.

Added header, fixed bugs and logic errors in point normals to target. Target location is now editable from UI.
Also renamed 'bmspacearr' to 'lnor_spacearr'

Remove support of lnorspacearray in editmesh undo/redo, fix memleak.

Supporting lnorspacearray in undo/redo would require a deep copy of lnor
spaces, not only a shallow copy of top struct. And it would eat a fair
amount of memory, think we'd rather recompute those on undo for now!

Also, fixed memory leaked by not correctly freeing lnorspace array on
BMesh deletion.

Do not include BKE_mesh.h in bmesh_class.h

We absolutely avoid such include unless totally mandatory, here we can
simply keep lnorspaces array a pointer in BMesh struct, and allocate it
on demand. Also, was breaking bmesh tests building.

Note: this totally breaks undo/redo, but previous code was utterly
wrong here as well (shallow copy of lnorspaces, ending up sharing whole
internal memory -> crash garanteed ;) ). Think we can skip that struct
for undo/redo for now at least, we can rebuild it in those cases imho...
