Show control edges stores the control edges in the mesh which is
picked up by the draw manager. When applyng a subsurf (or multires) we
don't want that data present in the base mesh. Any rebuilding of the mesh
would overwrite the data anyway.
This patch introduces a new flag for applying modifiers
that can be checked to ignore storing display specific data in
the base mesh.

Note that `BKE_library.h`/`library.c` were renamed to
`BKE_lib_id.h`/`lib_id.c` to avoid having a too generic name here.

C++ is used more and more, and it is becoming more and more annoying to
keep track of whether header have C++ guard or not.
Is easier and more clear to be consistent in all headers and have such
guards in all headers.

The `modifiers_getVirtualModifierList()` function previously took a non-
const `Object *ob` parameter, preventing it from being called from more
restrictive functions. Since the function doesn't modify the passed
object, it could easily be made const.
No functional changes.

This reverts commit 9e9fbb39d7f9e0a63c71fbc96237ace62fae0db6.
Adding back object+pose bone selection support removes the need for this fix.

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.

This saves memory and evaluation time for simple static meshes with e.g. a
subdivision surface modifier. If no CD_ORCO layer exists then we assume the
actual vertex coordinates are equal to the original undeformed coordinates.

A regression since 64c8d72ef1ad.
The solution is to force modifier evaluation for an evaluated
object, and let it to copy binding data back to original when
is being evaluated for binding.

The general idea of this change is to have a runtime data pointer
in the ModifierData, so it can be preserved through copy-on-write
updates by the dependency graph.
This is where subdivision surface modifier can store its topology
cache, so it is not getting trashed on every copy-on-write which
is happening when moving a vertex.
Similar mechanism should be used by multiresolution, dynamic paint
and some other modifiers which cache evaluated data.
This fixes T61746.
Thing to keep in mind, that there are more reports about slow
subdivision surface in the tracker, but that boils down to the
fact that those have a lot of extraordinary vertices, and hence
a lot slower to evaluated topology.
Other thing is, this speeds up oeprations which doesn't change
topology (i.e. moving vertices).

We already have different storages for cddata of verts, edges etc.,
'simply' do the same for the mask flags we use all around Blender code
to request some data, or limit some operation to some layers, etc.
Reason we need this is that some cddata types (like Normals) are
actually shared between verts/polys/loops, and we don’t want to generate
clnors everytime we request vnors!
As a side note, this also does final fix to T59338, which was the
trigger for this patch (need to request computed loop normals for
another mesh than evaluated one).

While \file doesn't need an argument, it can't have another doxy
command after it.

`BKE_modifier_get_evaluated_mesh_from_evaluated_object()` used by
modifiers needing access to other objects' geometry probably skipped out
of the radar when cage and final evaluated meshes were added to
BMEditMesh? In any case, we do not need to duplicate (and then free!) a
temp mesh from editdata anymore, and we can even add instead a parameter
to get cage instead of final. Also makes modifiers code a bit simpler.

BF-admins agree to remove header information that isn't useful,
to reduce noise.

Developers should add non license comments as separate comment blocks.
No need for separator text.

This is often invalid, outdated or misleading

It's more useful to git-blame to find out who has developed the code.

Was only used by subsurf in the past years, it is unlikely

The main goal of this patch is to cleanup the interface of every modifier. More specifically the interface of modifiers should be DerivedMesh-free.
Internally some modifiers still use DerivedMesh. However I think it is better when the wrappers are in the modifiers so that higher level functions can use the simplified interface.
This patch removes the applyModifier_DM and applyModifierEM_DM functions. In a previous patch (rB3614d9d) the other functions that used DerivedMesh have been removed.

Specifically the deformVerts_DM, deformMatrices_DM, deformVertsEM_DM and deformMatricesEM_DM functions are not used anymore.

This will allow modifiers to decide whether to copy or share caches between
ModifierData copies.
