Previously in 2.79 we were using a specialized drawing using derivedMesh.
Now the subsurf modifier tag each center vertex as facedot and let the
DRWManager pick it up.
Some modifiers (deforming ones) do not clear the tag so we can use this
technique even if there is deforming modifiers after subsurf modifiers.
The wireframe drawing for face masks is intrusive as selected wires
were solid white and always drawn. This made it hard for users to see
the exact color near edges.
This patch draws only the border of the selected faces,
edges between two selected faces are not drawn at all.

The fix itself is by Germano Cavalcante (mano-wii).
But since I was investigating this with him, I'm including here an
assert in EDBM_select_id_bm_elem_get to help catching this sooner
in the future
This type of indices is not natively supported on modern GPU and
gives warning on some implementation. The memory savings it
provides is also quite minimal and unlikely to be visible on
nowadays hardware.
This remove some uneeded struct members and makes primitive
restart always enabled by default. This can be broken by addons
if they are not careful enough but many other states have this
problem.
Also leverage GL_PRIMITIVE_RESTART_FIXED_INDEX if
ARB_ES3_compatibility is supported. This removes all API calls
to change restart index depending on indices length.
Enabling the drawing of the mesh analysis overlay.
Currently the settings are part of the scene toolsettings. What makes sense,
for 3d printing, but does not fit well with the per viewport blender 2.80
overlays.

This is only working for shading batches for the moment and only if some Custom data layer are not needed anymore.
The collection rate is hardcoded at 60 sec but could be exposed to the user.
This system can be extended and discard most unused batches in the future.
This commit is in prevision of removing BKE_MESH_BATCH_DIRTY_SHADING when changing shader parameters.
this was very similar to T60684 (and the UV case was actually reported
back then as well), so the fix goes hand in hand with rBbd8039399575
