Fix T61778: Crash when adding material slot to object

For some reason the mat_nr can be superior to the number of material slots
present on an object. Just cap this number to the max available slot.

Fix Cycles bug rendering with multiple UV maps after recent changes.

GPUMaterial: Make Shader Output nodes inside nodegroups work

Works as expected and mimics Cycles behavior.

The patch is a bit hacky: In order to not touch the lower level function,
we search for the active output inside groups (recursively) and the first
valid one is then copied (or extracted if you want) in the previous parent
nodetree. So we recursively extract the output node back to the main
nodetree while preserving the links through the nodegroups interfaces.

This way everything works as expected in gpu tree evaluation and bsdf
tagging.

Fix T61869 Material Output Node Inside Node Group Renders Pink in Eevee

DRW: Fix rasterizer discard messing with clear commands

Fixes T62179 Viewport Ghosting on rigs

BLI_memiter: use ASAN memory poison

Detects invalid memory use when WITH_COMPILER_ASAN is enabled.

UI: Nicer report when trying to edit external libraries

Rename 'libdata' to 'library data'.

Cleanup: warning in release builds

Fix T62208: constant detail picker not taking object scale into account

DRW: use memiter for on screen text allocation

Avoid allocation for each string,
improves redraw speed for text heavy views.

A contrived test showed FPS ~18.5% speedup but this doesn't represent
typical usage.

Fix T62210: endless loop in kd tree lookup

The problem was that `balance` expected that all node children
are set to `KD_NODE_UNSET` by default.
However, this might not be the case when `balance` is called
more than once.

The balance function might change the order of nodes even
when no new point has been inserted.

RNA: remove Screen.layout_name

This is no longer used.

Cycles: Changed standalone XML parser to read UV as float2

DRW: support clipping for bone verts

Tool System: add select tools to particle edit

Fix T62163: Duplicating particle system results in crash

There were two problems:
1. `mesh_get_eval_final` has to be called with the evaluated object.
2. Particle systems have to have unique names within an object.
The depsgraph seems to use the particle system name as identifier.
This issue is actually independent of duplication.
The old code used a small hack to create unique names.
