Sculpt dyntopo: fix bug with automasking being needlessly initialized

Fixed several build warnings

Sculpt dyntopo: fix symmetrix undo bug from last commit

Further refactoring WIP

Merge branch 'master' into soc-2021-vse-strip-thumbnails

fix type of code line being after the parenthesis
instead of before

Sculpt dyntopo: BMLog now uses the new bmesh unique id system

A few notes:

* MESH_ID layers are not saved on conversion to Mesh unless
you ask for it in BM_mesh_bm_to_me's params.
* Still need to test the box/lasso trim tools.
* Need to find some way to test loop/edge ids, which aren't
used by dyntopo.

Sculpt dyntopo: Added a function to add multiple customdata
layers to a bmesh at once. Helpful since bmesh customdata
layers are allocated in single blocks, thus adding
layers individually can lead to lots of memory
copying.

Sculpt dyntopo: Added (optional) support for unique mesh id tracking in
bmesh

* System is per element type. So you can have unique ids for verts and
faces, but not edges and loops.
* Supports an optional id to element lookup table.
* Uses single id space for all elements
* Added a new CD_FLAG_ELEM_NOCOPY flag to tell
customdata_bmesh_copy_data to ignore that layer.
* IDs are stored as a temporary customdata layer with
CD_FLAG_ELEM_NOCOPY set.

Fix T89330 Exact Boolean fails on a simple model.

The problem was an optimization I put in to triangulate quads.
It was wrong if the quad, after projecting onto a 2d plane, was
not convex. Handling quads the same as other faces fixes the bug.
Unfortunately, this will slow down Exact Boolean when the input has
many quads (the usual case, of course).
Will attempt to fix that with a later change, but for now, this
at least restores correctness.
