- All parts of the code that need tessface should calculate it on demand.
- The check for tessloopnormal mask isn't correct
(since this is loop data, not tessface data).
This is old logic that no longer makes sense in the new depsgraph, and causes
issues when multiple threads try to modify the same bevel object.

Curve function had two arguments:
- for_render, which was originally supposed to be used to control
whether viewport or render visibility for modifiers is to be
used.
- use_render_resolution, which sounds like it is supposed to control
whether viewport or render resolution for curves is to be used.
What is totally confusing is that those arguments were used
interchangeably: sometimes use_render_resolution would control
modifiers visibility.
This commit makes it so there is one single argument for this.

Force Displist to Mesh conversion if there is any modifier.
This is until we find a better way to store the batches per objects.
Also fix draw cache functions that were not returning final mesh edges.
This was caused by curves pointing to each other
creating a cyclic dependency.
While the dependency graph detects this, generating a mesh for render
recursively generates data which cashes in this case.
Add in a check to detect cyclic links.
Note, this bug exists in 2.7x too - but only crashes on render
since 2.7x didn't use 'for_render' when converting data.
Turns out most of our 'local working copy' cases can use same set of
flags.
Note that this commit adds LIB_ID_COPY_CACHES to all our local meshes
copying, however this is no-op since that flag is unused during mesh
copying... We may want to add another set of flags without that one at
some point, but for now it would not be useful imho.
BF-admins agree to remove header information that isn't useful,
to reduce noise.

Am not totally convinced that generating meshes without fully valid
material info is a good thing, but this seems to be rather common in our
code base (in both mesh editing and convert-to-mesh cases).
So for now, duplicated code in mesh eval finalization to main displist
creation/eval function, synchronizing mat data at the end of modifiers
stack eval, if needed.
Curve modifier eval code was actually doing nothing to ensure we passed
mesh with valid normals when required by the modifier.
This is a bit basic, rough code, but think it should cover all cases,
time will say...
Not exactly sure why we did not have cached displist for bevel object
here... But anyway, that conversion operation should really happen
outside of depsgraph evaluation area, so makes sense to do it as when
generating geometry for rendering, imho. Also solves issues like loosing
hidden parts of the curve/surface, etc. Still using viewport resolution
for curves, though.
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.

Since shape keys are stored as raw floating point data, this
unfortunately requires changes to all code that works with it.
An additional complication is that bezier and nurbs control
points have different entry size, and can be mixed in the same
object (and hence shape key buffer).
Shape key entries are changed from:
bezier: float v1[3], v2[3], v3[3], tilt, pad, pad;
nurbs: float vec[3], tilt;
To:
bezier: float v1[3], v2[3], v3[3], tilt, radius, pad;
nurbs: float vec[3], tilt, radius, pad;
The official shape key element size is changed to 3 floats,
with 4 elements for bezier nodes, and 2 for nurbs. This also
means that the element count is not equal to the vertex count
anymore.
While searching for all curve Shape Key code, I also found that
BKE_curve_transform_ex and BKE_curve_translate were broken. This
can be seen by trying to change the Origin of a Curve with keys.

The contents of the ModifierEvalContext struct are constant while iterating
over the modifier stack. The struct thus should be only created once, outside
any loop over the modifiers.
Makes the follow changes:
- Add new `deform*` and `apply*` function pointers to `ModifierTypeInfo` that take `Mesh`, and rename the old functions to indicate that they take `DerivedMesh`. These new functions are currently set to `NULL` for all modifiers.
- Add wrapper `modifier_deform*` and `modifier_apply*` functions in two variants: one that works with `Mesh` and the other which works with `DerivedMesh` that is named with `*_DM_depercated`. These functions check which type of data the modifier supports and converts if necessary
- Update the rest of Blender to be aware and make use of these new functions
The goal of these changes is to make it possible to port to using `Mesh` incrementally without ever needing to enter into a state where modifiers don't work. After everything has been ported over the old functions and wrappers could be removed.
