Bevel: fix regression re even adjustment of offsets.

Mistakenly had left a debugging assignment that disabled
the offset pass. This commit re-enables it.

Fix T61309: mesh_utils.triangle_random_points fails with a TypeError

Caused by an error in rBe65784a0519e.
And since we are going over loop triangles anyways, we can remove the
part quecking for quads [remainder of tessface era] entirely.

DRW: support clipping for stick & wire bones

Typo

UI: Icons for some Outliner context menu operations

Mainly 'X' icon for Delete, which was already on modifiers and constraints,
but not for objects. Select icon for object selection and refresh for library reload.

UI: Move View operations to submenu in Outliner context menu

Show One Level, Hide One Level, Show Active, Show Hierarchy were taking
four items on the context menu when they are not accessed that often
from the context menu (they all have shortcuts).

The "View" name is used to match other editors View menus.

UI: Icons for basic operations in Outliner context menu

Mainly the first of their category or when they need to be highlighted:
* Delete
* Enable Viewport/Render (match icons to make a visual connection)
* ViewLayers (it's used pretty often so it makes it easier to find)

Also group Show/Show All, Hide/Hide All together.

Fix T61231: File open and undo looses unkeyed changes

Only flush copy-on-write to animation when user makes changes.

DRW: edit-mesh edge clipping broke in recent update

Fix T61196: Mesh select ignores clipping (part 2)

Need to use local clipping planes in this case

Fix T61255: Mesh Data Transfer: Do not abort when destination has not all source data layers.

Originally, when transferring all source data layers to destination
meshes, code would abort in case destination did not have all needed
layers, and creating them was not allowed.

Now, it will instead transfer data to layers that exists, merely
skipping source ones for which it cannot find a matching destination.

Fix T58625: Knife project fails w/ curves

WM: init simulated event from win->eventstate

Ghost event handling code works this way.

Cleanup: rename V3D_MANIP_* -> V3D_ORIENT_*

Wasn't obvious it's related to orientation,
also term manipulator is no longer in use.

Fix T61291: Transform gizmo doesn't update w/ 3D cursor

Fix missing NULL check in recent version patch

Undo System: basic support in background mode

Some developers were using undo for their scripts, this allows for undo
pushes in background mode, however - as with 2.7x, undo isn't
initialized at startup in background mode.

See replies to T60934

Correct error in last commit

Cleanup: clear deprecated flags

Remove "Keep Session" preference

As far as we know this wasn't widely used, and relied no storing data
in the temp dir which may be cleared on reboot.

More generally, alternative behavior for a core area like file IO
is not something to keep if it has unresolved issues.

See D4310 for details.
