* Ensure that when new constraints are created, the new settings have sensible
default values.
TODO: we need to version-patch old files
* Fix problem with variable shadowing (which wasn't causing problems AFAIK)
From the looks of things, this was a typo. The result was that if you had a bone
with the minimum volume restriction in place, the bone would not get any thinner
when it was stretched out.
This commit adds a new type of volume preservation mode to Spline IK
which makes it possible to set limits on the minimum and maximum
scaling of bone "fatness".
* The old volume preseving mode has been kept but renamed, to avoid
breaking old rigs. "Volume Presevation" uses the new method, while
"Inverse Preservation" is the old one.
* The code and settings for this new xz scale mode are directly lifted
from the improved Stretch To constraint
Propper fix reverting most of rB60e70c0c6014e5, which was only partial specific fix.
This code uses generic `BKE_id_lib_local_paths()` func to handle all possible paths.

Check that up_axis is not aligned with bone was wrong in at least two aspects
(not working against negative alignement case, and since ages it seems,
using Z axis when bones are along Y axis...).
Also optimized a bit here, better to have a normalized version of vec_roll_to_mat3(),
since it needs normalized vector anyway, and we have to normalize it for the tests
before calling it anyway (so now, we only do that twice in Transform code, instead
of three times).
And we can perform aling test *before* calling vec_roll_to_mat3!
See T39470 and D436. Code by @tippisum, with some minor edits by @mont29.
Tested with various rigs, including Rigify, CGcookie flex rig, and gooseberry/pataz caterpillar.
Riggers, please test it, no change expected in behaviour.

Testing for custom data availability with getVertData and index 0 fails
on assert for empty meshes (the index must be in valid range). Better
use getVertDataArray which has no requirement for specific index.
Issue was caused by undefined object update order and in some
cases NULL pointer will be de-referenced.
Added on-demand curve path calculation, just the same creepy call
of BKE_displist_make_curveTypes(). This violates DAG and might
end up in a difficult to troubleshoot race condition if there'll
be some issues with how dependencies are calculated in DAG, but
this is the easiest and safest way to solve the bug at this stage,
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.

This solves threading conflict which happens when having
multiple objects using Curve Deform modifier with the same
curve datablock. This conflict was caused by the fact that
curve_deform_verts() used to temporary override curve's
flags to make it path is there.
Actually, it was setting CU_FOLLOW flag temporary which
was only used where_on_path() (only in terms that this
temporary assignment only affected this function) but it
is now commented out for a while, so no reason to set
this flag temporary, If it's ever to be done, we'll need
to pass flags as an additional function argument.
For the path creation i've extended DegNode structure
which now holds extra bits which indicates what additional
data depending on the graph topology is to be evaluated.
Currently this is only used to indicate that curve needs
path to be evaluated regardless to cu->flag state. This
is so Curve Deform modifier is always happy.
In the future this flag might also be used to indicate
whether bmesh verts are to update (see recent commit to
3-vertex parent crash fix) or to indicate that the object
is the motherball etc.
Apparently, some routines in armature deformation code
were using static arrays. This is probably just an
optimization thing, but it's very bad for threading.
Now made it so bbone matrices array is allocating in
callee function stack. This required exposing
MAX_BBONE_SUBDIV to an external API, This is not so
much crappy from code side, and it shall be the same
fast as before.

I know this is not so much nice to have this guys hanging
around in a general Object datablock and ideally they better
be wrapped around into a structure like DerivedMesh or
something like this. But this is pure runtime only stuff and
we could re-wrap them around later.
Main purpose of this is making curves more thread safe,
so no separate threads will ever start freeing the same path
or the same bevel list.
It also makes sense because path and bevel shall include
deformation coming from modifiers which are applying on
pre-tesselation point and different objects could have
different set of modifiers. This used to be really confusing
in the past and now data which depends on object is stored
in an object, making things clear for understanding even.
This doesn't make curve code fully thread-safe due to
pre-tesselation modifiers still modifies actual nurbs and
lock is still needed in makeDispListsCurveTypes, but this
change makes usage of paths safe for threading.
Once modifiers will stop modifying actual nurbs, curves
will be fully safe for threading.
Actually, this commit also contains wrapping runtime curve
members into own structure
This allows easier assignment on file loading, keeps curve-
specific runtime data grouped and saves couple of bytes in
Object for non-curve types.

Some places like proxy rebuild didn't increent
custom shape user counter which lead to user
decrement errors later when freeing pose channels.
Try to keep custom object counter relevent, but
some corner cases might still be missing.
Linked Armature with local proxy, using feature "Custom shape at other bone" stopped working
on undo/redo.
It was actually a bug in the original commit (r26600, april 2010), storing a pointer from
the library bone into the local proxy bone.
That's strictly forbidden in Blender, but it never showed up because on every undo-redo a
complete proxy-sync was called again. To allow undo/redo I had to disable this syncing,
except for file load. Hence the feature got lost :)
The fix is simple; just store the pointer to its own local bone instead.
Issue was caused by couple of circumstances:
- Normal Map node requires tesselated faces to compute tangent space
- All temporary meshes needed for Cycles export were adding to G.main
- Undo pushes would temporary set meshes tessfaces to NULL
- Moving node will cause undo push and tree re-evaluate fr preview
All this leads to threading conflict between preview render and undo
system.
Solved it in way that all temporary meshes are adding to that exact
Main which was passed to Cycles via BlendData. This required couple
of mechanic changes like adding extra parameter to *_add() functions
and adding some *_ex() functions to make it possible RNA adds objects
to Main passed to new() RNA function.
This was tricky to pass Main to RNA function and IMO that's not so
nice to pass main to function, so ended up with such decision:
- Object.to_mesh() will add temp mesh to G.main
- Added Main.meshes.new_from_object() which does the same as to_mesh,
but adds temporary mesh to specified Main.
So now all temporary meshes needed for preview render would be added
to preview_main which does not conflict with undo pushes.
Viewport render shall not be an issue because object sync happens from
main thread in this case.
It could be some issues with final render, but that's not so much
likely to happen, so shall be fine.
Thanks to Brecht for review!
Change Scene.frame_set so that it ensures subframe in range [0,1[ as Blender
expects, otherwise some things like physics point cache lookups don't get
evaluated properly.
