Fix cycles crash when voxel attributes changed

This could happen e.g. when changing smoke type from flow to domain or
connecting a volume shader with to a domain without an actual flow type
around.

Shading: Add a clamp option to the Map Range node.

If the option is enabled, the output is clamped to the target range.
The target range is [To Min, To Max]. The option is enabled by default.

The clamp option is implemented in EEVEE by linking to the `clamp_value`
GLSL function. And it is implemented in Cycles using a graph expand
function.

Fix T68597: GPencil Dope Sheet can fail to display active GP object

Now, the dopesheet is activated if the object is in any Edition mode.

cleanup: fix python related build error on windows.

Recent python changes caused issues on some systems.

make.bat: Support running python from lib folder for make format

We are no longer depended on a system python being installed.

deps: python 3.7.4 for windows.

This also updates to a new packaging method where python is runnable
from the library folder rather than having tarballs in the release
folder.

deps/cleanup: remove partial boost-python support.

boost python was not required by any dependency nor was it ever properly supported.

build_environment/python: Bump versions of our site-packages

IDNA 2.8
CHARDET 3.0.4
URLLIB3 1.25.3

Shading: Add Clamp node to Cycles and EEVEE.

This patch adds a new node that clamps a value between a maximum and
a minimum values.

Shading: Add Map Range node to Cycles and EEVEE.

This patch adds a new Map Range node that linearly remaps an input
value from a range to another. This node is similar to the compositor's
Map Range node.

Fix T67516 VSE: Animation evaluated incorrectly when scene strip present

The calls to `BKE_animsys_evaluate_all_animation()` and
`BKE_mask_evaluate_all_masks()` used the wrong timecode to evaluate the
animation system. This happened:

- Sequencer in scene A was rendered at frame X.
- Scene strip for scene B which should be evaluated at frame Y.
- BKE_animsys_evaluate_all_animation() was called with frame Y, which
also re-evaluated the animation data in scene A.
- Other sequencer strips with animated values were then evaluated for
frame Y and not frame X.

Since the depsgraph for rendering the scene strip is already OK and does
its job, it's no longer necessary to re-evaluate all the animation in
this way.

Removed `BKE_mask_evaluate_all_masks()` because it's no longer used.

Custom Properties: officially support int and float arrays in the UI.

In some rare cases it is convenient to store a short array value
as a custom property, e.g. a vector or color. For example, it may
be helpful when importing/exporting certain formats that support
custom or nonstandard attributes on objects.

The custom property storage already can handle arrays in order to
support properties defined via python. The only thing missing is
UI support (and some bugs), and this patch fixes that:

- Allow editing short array properties via Custom Properties panel.
- Fix a UI layout sizing bug triggered by the previous item.
- Fix a dependency graph bug with drivers using such properties.
- Make RNA_*_get_default_array code robust in case of size mismatch.
- Support custom default values for array properties, allowing
both an array and a scalar value.

UI: Fix wrong properties being grayed out

This has been mentioned in T68610.

Fix T66373: Strange translation text behaviour.

i18n code does not work from threads on some plaforms, so it is disabled
in Blender when called from non-main thread.

Means that we have to go to a slightly different approach, with dirty
tag and generating string on request for UI.

Note: Also had to update the `info` string size, to fit with expensive
asiatic scripts in utf-8... Using mem for that kind of runtime data is
not really nice, but for now it will have to do.

Add mathutils.geometry.delaunay_2d_cdt() function to Python API.

Provides Python API access to recently added Constrained Delaunay
Triangulation routine.

Fix T65670: bone envelope head radius missing from transform panel

Make the transforms section of the properties panel consistent with
the transforms section of the side-bar, and to expose some currently
hidden BBone properties in the Bendy Bone section.

- Object transformations were not consistent with Pose Bone
transformations in that they did not use single-column layout.

- Even in Pose Bone transformations,
the rotation mode option was after Scale.

- Edit Bone Transforms panel included "Tail Radius" and
"Envelope Deform Distance", neither of which belong there. See T65670.

- Expose bbone_x and bbone_z.

Fix build errors with older GCC versions like 4.9

We can add more fine grained checks for when these flags are supported so
that adding asan flags manually still has all the workarounds, but for now
compiling succesfully is more important.

Fix T68547: Plane Constraint inaccuracy

If it is to prevent division by zero just check if the `factor` is zero (instead of using an epsilon).
