Fix for Constraints Head/Tail on BBones

Last segment needs special handling, as the values there are a little wonky...

Constraints: Head/Tail interpolation follows bbone shape, instead of doing straight-line interpolation

This can be used to reduce the complexity of rigs, by reducing the number of extra bones
that may have otherwise been needed to accomplish a similar effect.

Bendy Bones: Tweaks to UI layout for Bendy Bones panel

* Disable all properties if no segments
* Better labels and spacing of items
* Changed order of things to have a better layout
* Moved "inherit endroll" option into this panel too

Bendy Bones: Fix - Scale In/Out not being initialised for new pose bones

Bendy Bones: Code Cleanup - Expose equalize_bezier() as equalize_bbone_bezier()

Bendy Bones: Curved Bone settings in EditMode act as "Rest Pose" (Experimental)

The bendy bone settings (curve in/out, etc.) now exist on both Bone and PoseBone
levels. What this means is that the "Bone" level settings (i.e. what we had before)
are used for defining the rest pose curve for the bone (i.e. to fit things like
curved eyebrows, and so forth), while the "PoseBone" level settings (i.e. new stuff)
will be what animators play with to animate their characters.


Implementation Notes:
* All the BBone settings are now found in a new "Curved Bones" panel. This is located
just below the Transform properties panels (instead of by "Deform"), so that it's
easier to reach for animating.

The segments and ease in+out settings are still also located in the "Deform" panel.
I'm still unsure whether to remove them for good from there. For now, I've duplicated
them, to be more convenient for animation tweaking (though it might also be a bit
confusing)

* Ease In/Out is still a bone-level setting only (i.e. no posemode offsets/override).
This may be subject to change still, but more investigation will be needed first.

* Scale In/Out is handled multiplicatively. That is,
scaleIn_final = bone->scaleIn * pbone->scaleIn

* I've added a hacky "stripped down" copy of b_bone_spline_setup() for drawing
the editmode previews of these bbone settings. Whether this is the final approach
used is still open to debate. Better suggestions welcome, though this seems to be
the simplest (least overhead) solution currently.

Bendy Bones: Fix tooltip for "Inherit End Roll" to be a bit more descriptive

Bendy Bones: Restore bone->ease1/2 for hlength1/2 calcs

It turns out that this wasn't changed in the patch after all...

Bendy Bones: Fix for crash when enabling "Inherit EndRoll"

Bendy Bones: Code Cleanup - Remove all the unnecessary prints + debug code leftover

Bendy Bones: At last, it works!

I've gone through making a bunch of changes (mostly, just reverting quite a few
things back to their pre-patch state, and adding in a few other bits), and it
finally looks like it actually works for both BlenRig and the test files. Yay!

(Things are still quite messy, with a lot of commented out leftovers and stuff
to deal with, which I'll clean up in a moment after verifying that it all actually
works for real)

BendyBones WIP - Temporarily knocked out change to the matrix multiplication final step

If we use the old formula (currently enabled), old rigs work, but new options don't.

However, if we use the new one (without tmat == inverse mats[0]), old rigs
(blenrig) breaks, while the new options don't really work that great.

BendyBones - Note about potential cause of segment length + blenrig bugs

Code Cleanup - Remove some more leftover gunk

Version patching fixes for the new bbone settings

Code Cleanup: Removed some obsolete code that seems to be left over from previous experiments

Code Cleanup - More style cleanups and removing unneeded extra steps

UI Tweak: Rename labels to be easier to read with typical panel widths

Code Cleanup

* Roll angles should be stored in radians, and displayed using the appropriate
RNA type instead
* Some general code cleanup work (style, avoid type conversions, etc.)
