Both original handle types are based on location, and Absolute uses it
in a weird way: the Start handle uses the head, while End uses the tail.
This makes controlling the shape of the B-Bone via control bone rotation
really non-intuitive, especially if trying to add a single control for
the tangent in the middle of a B-Bone chain.
To remedy this, add a new custom handle type that uses the orientation
of the control bone, while completely ignoring location. It is even
possible to control both ends of one B-Bone with the same handle bone,
resulting in an S shape.

Specifically, it should always use the position of the custom handle
bone head, even when affecting the handle at the tail of the main bone,
and shouldn't apply the special handling for joining two B-Bones.
This handle type was unusably broken before a bug fix included in
recent changes, so it should be safe to break backward compatibility.
The grid now can be configured by object because this helps to identify objects and allows to define diferent grid parameters for each objects.
Also added a color option.
The rest shape of B-Bones is actually affected by custom handles or
the default connected parent/child mechanism. Ignoring these effects
thus leads to the edit mode shape being different from the actual
rest pose.
This splits the b_bone_spline_setup function that is used to compute
the correct rest and pose shape from pose channels into two parts,
and applies the data structure independent half to edit mode.
In order to access the custom handle settings in Edit Mode, they are
moved to Bone and EditBone, while the bPoseChannel fields are downgraded
in status to a cache for performance. Also, instead of flags, introduce
an enum to specify the handle operation modes, so that new ones could
be added later.

Custom handle settings actually affect the B-Bone rest shape,
so they should be changed in Edit mode rather than Pose mode.
This is necessary to be able to display the correct rest shape
of the bone in Edit Mode.
Also, instead of flags, introduce an enum to specify the handle
operation modes, so that new ones could be added later.

Users can select the main unit they want to use now.
Previously the displayed unit always depended on the magnitude of the value.
The old behavior can be restored by switching to the "Adaptive" mode for length, mass and time units.
Meters, kilograms and seconds are the default units for new and old scenes.
The selected unit is also the default unit for user input.
E.g. if cm is selected, whenever the user inputs a unitless number into a field of type length, it will be interpreted as cm.

Allow raycasting in two directions and culling front or back faces.
Also implement a new Invert Cull option in both constraint and
modifier that can be used to aim for faces aligned with the project
axis direction when raycasting both ways.

This commit make the Xray option for the wireframe different from the other
shading mode. This makes it possible to rapidly switch between wireframe +
Xray and Solid mode without Xray.
Xray alpha is also decoupled.
Both variables are duplicated and exposed separately through RNA.
This commit includes several performance, stability, and reliability
improvements to cloth collisions.
Most notably:
* The implementation of a new self-collisions system.
* Multithreading of collision detection.
* Implementation of single sided collisions and normal overrides.
* Replacement of the `plNearestPoints` function from Bullet with a
dedicated solution.
Further, this also includes several bug fixes, and algorithmic
improvements.

In addition to the original map to surface and Keep Above Surface,
add modes that only affect vertices that are inside or outside
the object. This is inspired by the Limit Distance constraint,
and can be useful for crude collision detection in rigs.
The inside/outside test works based on face normals and may not be
completely reliable near 90 degree or sharper angles in the target.

This makes the Edit Mesh display settings common to all objects. They can
also be set differently per viewport.
Modifying extra data (seams, sharp edges etc...) will no longer set them
automaticaly visible.
Bumping version because we need to force set all extra draw options for
older files.
As the comment states, this is not really great solution, but
is good enough for now. Proper solution needs some more work,
and maybe reconsideration of what is stored where.
