C++ does not allow the assignment of a void pointer to a typed pointer without
explicit casting. Since we use a generic macro in bmesh for iterators we only
ever get a void* back and cannot cast it to the target type. However, casting
the target to a void* as well solves that issue.
This tweak is #ifdef'd to be used in C++ code only.
note, this is for C++ code which expects a cast, (will be added later)
also add a macro for nop-expressions (EXPR_NOP),
when we never want an expression to be evaluated, but it should still be valid.
* Merely a re-implementation of core split algorithm for BMesh, taking advantage of topological data available.
* This code needs valid loop indices, so added BM_LOOP support to BM_mesh_elem_index_ensure() & co.

since enough bmesh operations can also take advantage of direct index lookups on verts/edges/faces.
developers note:
- EDBM_index_arrays_init/ensure/free -> BM_mesh_elem_table_ensure/init/free
- EDBM_vert/edge/face_at_index -> BM_vert/edge/face_at_index
- EDBM_uv_element_map_create/free -> BM_uv_element_map_create/free
- ED_uv_element_get -> BM_uv_element_get
- add missing headers from cmake (own omission)
- quiet rna_test.c unused define warnings.
- minor style edits
- spelling corrections and ignore all uppercase words with spell checking script.
- without python builds without warnings.
- replace MAXFLOAT -> FLT_MAX in some areas, MAXFLOAT overflows (lager then float range).
- add cmake option WITH_GCC_MUDFLAP to enable libmudflap use.
- BM_mesh_elem_toolflags_ensure / bmo_flag_layer_alloc / bmo_flag_layer_free / bmo_flag_layer_clear
- BM_mesh_select_flush
- EDBM_index_arrays_init
notes:
- mostly use openmp `sections` to split operations on vert/edge/face since this is a fairly minor change.
- split tool flag pool in 3, this means we can allocate exact sizes needed and iterate on them in threads without alloc'ing.
add type checking for element buffers, there was nothing stopping python from passing any element type into an argument when in some cases only verts/edges/faces were expected.
now operator args define which types they support.
- don't collapse boundary verts into non boundary edges (was ugly causing spikes)
- handle degenerate cases better, rather then removing double edges after collapse, check before collapsing that there won't be any degenerate faces/edges.
- memset(..., -1) is used incorrectly even though it worked: MOD_solidify.c - thanks Halley from IRC for noticing this. use fill_vn_i() instead.
- quiet warnings in editmesh_slide.c
- cleanup comments in bmesh and some other minor comment additions.
- spelling - turns out we had tessellation spelt wrong all over.
- use \directive for doxy (not @directive)
- remove BLI_sparsemap.h - was from bmesh merge IIRC but entire file commented and not used.
* made bmesh_structure.h function names more consistant.
* remove unused code in bmesh_structure.c
* removed 'Edge Flip' operator (missing from bmesh but looked into trunk feature and dont think its worth keeping).
* tagged some BMESH_TODO's
* better type safety for BM_elem_flag_* and BM_elem_index_* functions.
* add BMElem type to be used where BMFace/Edge/Vert/Loop can be interchanged.
* fix bug in select manifold, found when making functions more strict.
