3D View: remove 3D cursor

Use 3D cursor from the scene (was previously used for local-view).

Fix extended shading pie menu not having same order as before.

Cleanup: unused vars, imports

Cleanup: unused vars, imports

Fix some errors in the Blender Light theme.

Fix missing versioning code for user preferences navigation bar.

Tools: add Select tool, with transform tweak on drag and no click delay.

For users that want the 2.7 LMB keymap behavior, this provides a way of
working without tools interfering. For RMB select this operator is quite
redundant with the Cursor tool, we may have to find a solution for that.

Note that we also might later add transform tweak to the transform tools,
when nothing is selected. But this is important for existing users who
preferred the existing workflow.

Keymaps: add 3D view click empty space to deselect all.

The implementation of this operator was modified to be more efficient and
ensure the undo history has the exact operator used.

Cleanup: Silent compiler warning

A void function cannot return a value.

UI: Disable font shadow in tooltip

When I added this a few years ago, it was meant to create a fake bold effect.
With the new text shadow drawing code, that doesn't work well though.

Fix mesh_build_data() calling mesh_finalize_eval() before copying texspace.

mesh_finalize_eval() may set ob->data to evaluated mesh, needs to be
done *after* call to BKE_mesh_texspace_copy_from_object(), else that one
is meaningless.

Related to investigations on T57985, but does not solve it at all. :(

Cleanup: remove useless redundant NULL check.

Fix T57070, T57389, and other bbox-related issues with meshes.

Thinks whole bbox code needs a complete rewrite, one can see a lot of
old history in it, it has way too many functions doing
nearly-the-same-thing(c), it spreads in very inconsistent ways across a
lot of files, ... But have no time for this right now, and would not be
a good idea with Beta comming up close anyway.

So for now going the simple and (hopefully) sane & safe way: forbid
object-level functions to affect data-level bbox. Mesh and curve ones
would generate bbox in obdata instead of object, for some reason (all
other obdata types only use object's bbox ever). That may have been
working in old ages, but with CoW and threaded depsgraph this is just
calling for piles of issues.

UI: Disable font shadow in tabs

This was used to fake a 3D look, however that doesn't work well with the new,
flat style. It just made text appear blurry.

UI: Initial User-Preferences redesign

Implements the first changes for T54115:

* Rename "User Preferences" window to "Settings" in the UI.
We'll likely put workspace settings in there, separate from the global
user settings. System settings should become separate from user
settings in future to allow settings for specific hardware.
* Add sidebar region for navigation (scrolls independently).
Addresses space problems, so we can add more categories as needed now.
* Increase size of Settings window to compensate new navigation bar.
* Group sections into User Preferences and System.
Icons for section groups by Andrzej Ambroz. Thanks!
* Bumps subversion for file compatibility.

I also added categories for future work, but commented them out.
We may also want to redesign contents of each section now.

Texture Paint: prevent normal angle masking duplicating backface culling.

If backface culling is off, the user obviously wants to paint on
back faces, so the normal angle cutoff designed to prevent painting
at glancing angles shouldn't do the culling as a side effect.

Local View

Bring back per-viewport localview. This is based on Blender 2.79.
We have a limit of 16 different local view viewports.

We are using both the numpad /, as well as the regular /.

Missing features:
* Hack to make sure lights are always visible.
* Make rendered mode with external engines to support this as well
(probably just need to support this in the RNA iterators).
* Support over 16 viewports by taking existing viewports out of local view.

The code can use a cleanup pass in the future to unify the test to see
if an object is visible (or we can use TESTBASE in more places).
