Geometry Nodes: Allow node group inputs with the same name

If we add the "name" label manually with uiItemR, we can use the socket
identifier instead of the name for the IDProperty name. This will also
allow us more flexibility in how to draw the settings in the future, and
removes the empty _RNA_UI proprety that was drawn before.

GPencil: New material parameter to rotate texture

Add a parameter to rotate the texture for Dots and Squares

Merge branch 'blender-v2.91-release' into master

Fix (unreported) buffer-overflow in new lattice code.

Follow-up to rBc0beeeb5de0cbc, fixing overflow accesses on arrays
introduced by rB042143440d76.

It's never 'OK' to access invalid memory...

Refactor: move Area .blend I/O to blenkernel

There should be no functional changes.
Eventually, it would be good to handle the different space types
using callbacks.

Ref T76372.

Fix Cycles map range node missing clamp socket

No effect on the Blender integration yet, but needs to be solved for the
upcoming change to encapsulate sockets.

Fix buffer-overflow in lattice deform evaluation

Caused Victor.blend from the cloud to crash with ASan. Four floats are
fetched from the stack, but the buffer was only three wide.

Caused by 042143440d. Issue was probably harmless since the fourth
element wasn't actually touched.

Refactor: move view3dshading .blend I/O to blenkernel

Refactor: move ParticleSettings .blend I/O to IDTypeInfo callbacks

Parenting: fix return value when parenting object to itself

Ensure parenting an object to itself is seen as error, by returning
`false`.

This error was introduced as part of a supposed-to-be-non-functional
cleanup rBb8d4a2aff8069dd7d6fb91ad0d9427eed489b68f.

Fix undo steps not allowing re-using old BMain in non-global undo.

Non-memfile undo steps never properly initialized the flag allowing to
re-use old Main data during undo/redo. This lead to doing a complete
full re-reading of data when undoing/redoing mode switches e.g.

Note that current undo system is supposed to support any kind of mode
switch across those steps, however this needs to be properly deeply
tested, so only comitting this to master. It would be way too risky for
2.91 release.

Fluid: Cleanup for APIC debug build setup

Fixes build issue

Cleanup: malformed doxygen sections

Animation: move group colors switch to user preferences

Move the "Show Group Colors" toggle from a per-editor option to a single
user preference in the Animation preferences.

The old "Show Group Colors" toggle had to be set per editor, and was on
by default. This meant that disabling group colors would require an action
for every file, for every editor.
