EditDerivedBMesh (edit mode DM) only gets a dummy one in this commit.
* Add a tessellated version of CD_LOOPNORMAL layer (CD_TESSLOOPNORMAL), with relevant code to handle it

* Change auto_smooth options of Mesh (angle now in radian internaly, and toggle is now used to enable/disable
split normals in DM creation process). Note BI render code is not touched here, hence its behavior regarding
this option is now incoherent, will be addressed in a separate commit.

There is no good solution here, since RNA props can only have one type/unit.
Tried to find the less worse one - have different RNA props for same DNA value
(a bit like the angle/length for camera lens).
Also fixed two other issues with Transform conctraint:
* Angle were still in degrees (yes, another backward-compatibility breacking).
* Scale was absolute, unlike loc/rot.
Also cleaned up a bit the code, replaced some magic numbers by proper enums, ...
This is done by adding a new button type, GRIP, similar to other numbuttons
(scroll, slider, ...), which here controls the preview height.
Then, we add a new DNA struct to be able to save that height in Blend files
(note I choose not to use Panel struct for this, because we would then have the
same limitation we used to have with uiLists, only one preview per panel
and no preview outside panel).
This implies a change to template_preview UI RNA/py API (each preview needs an ID),
but this is backward compatible, as by default datablock type will be used if no ID is
given (which means e.g. all material previews with no ID will have same height).

There is not much sense to have a whole BLI file just to check SSE2 on CPUs...
So idea is to rename it to more generic "BLI_system", and add to it more system-related
utils, like e.g. an include helper for getpid(), which allows to hide unix/windows
internals from rest of the code...

Bevel Factor Mapping allows to control the relation between bevel factors
(number between 0 and 1) and the rendered start and end point of a beveled
spline.
There are three options: "Resolution", "Segments", "Spline". "Resolution"
option maps bevel factors as it was done < 2.71, "Spline" and "Segments"
are new.
* "Resolution“: Map the bevel factor to the number of subdivisions of a
spline (U resolution).
* "Segments“: Map the bevel factor to the length of a segment and to the
number of subdivisions of a segment.
* "Spline": Map the bevel factor to the length of a spline.

in threaded depgraph updates and effector list construction.
Gathering effectors during depgraph updates will call the
psys_check_enabled function. This in turn contained a DNA alloc call
for the psys->frand RNG arrays, which is really bad because data must be
immutable during these effector constructions.
To avoid such allocs the frand array is now global for all particle
systems. To avoid correlation of pseudo-random numbers the psys->seed
value is complemented with random offset and multiplier for the actual
float array. This is not ideal, but work sufficiently well (given that
random numbers were already really limited and show repetition quite
easily for particle counts > PSYS_FRAND_COUNT).
undo with a nicer enum.
This is more transparent about what happens with the user count.
Also added comments to make certain the meaning of these values is
easily understandable.
The node editor needs to "ensure real user" (id_us_ensure_real) on all
the node trees. This was done correctly for all open groups, but missing
for the base node tree. Function is a bit hidden behind anonymous
arguments in readfile.c ...

This commit organized panels for image editor to new tab categories dependent
on the image editor mode:
View Mode:
Tools - contains UV tools (currently only transform and UV Sculpting)
Scopes - contains scopes
Grease Pencil - contains Grease Pencil operators
Paint Mode:
Tools - contains brush options
Scopes - as above
Grease Pencil - as above
Mask Mode
Mask - contains mask tools
Scopes - as above
Grease Pencil - as above
Grease Pencil panel/tab now includes operators, not view options which have been
moved to the UI region on the right.
To make this work better, image editor toolbar now is of type TOOLS instead
of PREVIEW as was the case previously. A nice version patch makes sure all
works predictably, but opening newer files with older blender executables
could backfire.
This commit does not address which UV Tools will be included in the
Tools tab for the view mode, but does include some basic tools (transform)
and provides a class to inherit from to avoid conflicts with UV Sculpting.

The "Cast Shadows" worked as expected, but it can cause problem in some cases.
For example, when using strand render, we need disabling only buffer shadows,
but the previous changes made that impossible. "Cast Shadows" should be added
as a newly created option.
This allows us to make materials that don't cast ray shadows.
Turning off this property can reduce the rendering time slightly.
Note: RNA path is changed to "use_cast_shadows" as well. The older
path "use_cast_buffer_shadows" still can be used as its alias, but
it will be removed after updating some addons.

Z, Index, normal, UV and vector passes are only affected by surfaces with alpha
transparency equal to or higher than this threshold. With value 0.0 the first
surface hit will always write to these passes, regardless of transparency. With
higher values surfaces that are mostly transparent can be skipped until an opaque
surface is encountered.
It was intended to work actually using particle cache's stack index
but this index might have been calculated incorrect in special case:
* With default cube scene, add particle system to the cube
* Add disk cache to the particle system
* Save file and reload it
* Add another particle system and enable disk cache
This would lead to two point caches with the same stack index of zero.
This happened because point cache indices list wasn't stored in the
.blend file so once you've reload your file blender doesn't know anything
about number or point caches used.
And what was even more confusing is that point cache indices list was
trying to be load from the file, but this failed because it wasn't in the
file.
This commit solves the root of the issue which is ability of producing
.blend file with two point caches using the same disk cache. This is
done by making it sure that point cache indices list is stored in the
.blend file. And also made it so disabling disk cache will tag it to
recalculate stack index.
Old broken files wouldn't magically start working, but fixing them is
rather simple manually by toggling Disk Cache option.

As discussed in T38340 the solution is to use the current scene from
context whenever feasible.
Composite does not use node->id at all now, the scene which owns the
compositing node tree is retrieved from context instead.
Defocus node->id is made editable by the user. By default it is not set,
which also will make it use the contextual scene and camera info.
The node->id pointer in Defocus is **not** cleared in older blend files.
This is done for backward compatibility: the node will then behave as
before in untouched scenes.
File Output nodes also don't store scene in node->id. This is only needed
when creating a new node for initializing the file format.

Added function called WM_set_locked_interface which does
two things:
- Prevents event queue from being handled, so no operators
(see below) or values are even possible to run or change.
This prevents any kind of "destructive" action performed
from user while rendering.
- Locks interface refresh for regions which does have lock
set to truth in their template. Currently it's just a 3D
viewport, but in the future more regions could be considered
unsafe, or we could want to lock different parts of
interface when doing different jobs.
This is needed because 3D viewport could be using or changing
the same data as renderer currently uses, leading to threading
conflict.
Notifiers are still allowed to handle, so render progress is
seen on the screen, but would need to doublecheck on this, in
terms some notifiers could be changing the data.
For now interface locking happens for render job only in case
"Lock Interface" checkbox is enabled.
Other tools like backing would also benefit of this option.
It is possible to mark operator as safe to be used in locked
interface mode by adding OPTYPE_ALLOW_LOCKED bit to operator
template flags.
This bit is completely handled by wm_evem_system, not
with operator run routines, so it's still possible to
run operators from drivers and handlers.
Currently allowed image editor navigation and zooming.

This commit introduces the ability to make the Build Modifier operate in reverse,
essentially allowing it to be used as a "deconstruction" effect.
(See D219 for more details about use cases for this)
Previously this only worked for some datablocks relevant to rendering, now it
can be used to detect if any type of datablock was added or removed (but not
yet to detect if it was modified, we need many more depsgraph tags for that).
Most of the changes are some function parameter changes, the important parts
are the DAG_id_type_tag calls.

EditFont's use of Curve.len was very confusing, in editmode it
represented the number of characters, in object mode the number of
bytes. add Curve.len_wchar and keep track of both.
Also don't convert the editmode text into utf8 on every keystroke.
Now this is done on exiting editmode or save - to match most other
object types.
This also fixes curves 'body_format' being reported with an invalid size.
Summary:
Crash was happening because of fcurve modifier stack
used modifier's DNA to store temporary data.
Now made it so storage for such a thing is being
allocated locally per object update so multiple objects
which shares the same animation wouldn't run into
threading conflict anymore.
This storage might be a part of EvaluationContext,
but that'd mean passing this context all over in
object_where_is which will clutter API for now without
actual benefit for this.
Optimization notes: storage is only being allocated
if there're Cycles modifier in the stack, so there're
no extra allocations happening in all other cases.
To make code a bit less cluttered with this storage
passing all over the place added extra callbacks to
the FModifier storage which runs evaluation with the
given storage.

Summary:
Made objects update happening from multiple threads. It is a task-based
scheduling system which uses current dependency graph for spawning new
tasks. This means threading happens on object level, but the system is
flexible enough for higher granularity.
Technical details:
- Uses task scheduler which was recently committed to trunk
(that one which Brecht ported from Cycles).
- Added two utility functions to dependency graph:
* DAG_threaded_update_begin, which is called to initialize threaded
objects update. It will also schedule root DAG node to the queue,
hence starting evaluation process.
Initialization will calculate how much parents are to be evaluation
before current DAG node can be scheduled. This value is used by task
threads for faster detecting which nodes might be scheduled.
* DAG_threaded_update_handle_node_updated which is called from task
thread function when node was fully handled.
This function decreases num_pending_parents of node children and
schedules children with zero valency.
As it might have become clear, task thread receives DAG nodes and
decides which callback to call for it.
Currently only BKE_object_handle_update is called for object nodes.
In the future it'll call node->callback() from Ali's new DAG.
- This required adding some workarounds to the render pipeline.
Mainly to stop using get_object_dm() from modifiers' apply callback.
Such a call was only a workaround for dependency graph glitch when
rendering scene with, say, boolean modifiers before displaying
this scene.
Such change moves workaround from one place to another, so overall
hackentropy remains the same.
- Added paradigm of EvaluaitonContext. Currently it's more like just a
more reliable replacement for G.is_rendering which fails in some
circumstances.
Future idea of this context is to also store all the local data needed
for objects evaluation such as local time, Copy-on-Write data and so.
There're two types of EvaluationContext:
* Context used for viewport updated and owned by Main. In the future
this context might be easily moved to Window or Screen to allo
per-window/per-screen local time.
* Context used by render engines to evaluate objects for render purposes.
Render engine is an owner of this context.
This context is passed to all object update routines.
