Fix T90256: faces are flat shaded in edit mode with auto smooth

Regression in 39b2a7bb7e815e051348bf5c5ec777d091324164.

Fix compiler warnings: unused variables

Cleanup: remove redundant parenthesis

Fix slicing with negative indices

Negative indices that remained negative after adding the sequence length
caused incorrect slicing.

With the default scene for example:

bpy.context.scene.objects[-4:2]

Gave a different result to:

tuple(bpy.context.scene.objects)[-4:2]

Clamp indices above zero so loops that step forward works as intended.

Fix T89450: Crash slicing BMEditSelSeq

Slicing with indices greater than the length of the sequence would crash.

adaptive_cloth: fix: mesh: flip edge: edge might already exist

It is possible that there might already be an edge between ov1 and ov2
so it is best to not create a new edge between those because edges
between verts should always be unique for all the algorithms to work
correctly.

It is a case that shouldn't show up too often but when it does, it
will be interesting to see what happens in the static remeshing
part. The number of faces remains the same but number of edges can
change (reduce only).

Cleanup: Fix Clang braced-scalar-init warning

XR: Action Binding Improvements

Provides several important improvements to the runtime action
bindings operation and internal API.

Moves input-specific action data (input thresholds, input regions,
pose offsets/spaces) from actions to more granular action bindings.
This allows a single action to be mapped to a variety of inputs,
without having to share a single input threshold, region, or space.

Also removes the need for action space creation API, as spaces for
pose actions will be automatically created with the bindings.

The correct action data for the current inputs is set by calling
xrGetCurrentInteractionProfile() to get the current profile and then
retrieving the corresponding mapped data.

Does not bring about any changes for users since only internal
runtime functionality is currently affected.

Cleanup: tab indentation for CMake / GNUmakefile

Cleanup: license headers

These were removed globally in 65ec7ec524e667ec95ce947a95f6273088dffee6.

Some files re-introduced these conventions since.

Enable OmniPanel addon on startup

Added C calls to enable the OmniPanel addon
on startup.

Windows: Add icons and icons_geom to make.bat

This adds support for building the icons from make.bat
unlike bash there is no passing environment variables
on the command line.

The scripts go out of their way to locate both blender
and inkscape however if they are not found, the user is
given a helpful error message telling them how to set
the variables.

Although some extra help can be given there, if your
normal build is a 2019 full build running

`make 2019 full icons`

will help it find the blender executable as well.

finally if you know the name of your build folder
running

`make builddir build_windows_Lite_x64_vc16_Release icons`

will also work, if all fails you can point directly to
the blender executable by running

`set BLENDER_BIN=c:whereblenderlivesblender.exe`

before running `make icons` or `make icons_geom`

The python scripts needed some small modifications since
without the PATHEXT, SystemRoot and SystemDrive
environment variables python will not initialize properly
on windows. (Not blender related, even mainline python
won't start without those)
