Fix crash on rna show diffuse color update

(untested because texture painting is not working)

Fix T51624: Scene Full Copy ignores shader node links.

Properly remap nodes' pointers to copied IDs in copied ntrees.

Note that this only affects root trees, node groups are not concerned
here, since they are assumed to be reusable chunks and hence *not*
duplicated.

Fix crash when setting sculpt settings

UI: Make GP "Add Blank Frame" operator name and description fit its behavior.

The operator is indeed not adding frames but inserting them at the current frame (shifting all subsequent ones). Changed the operator name and description.

Approved by Antonio.

Fix T51646: Motion Tracker instantly crashes

Was a mistake in previous changes.

Weirdly enough, frame reading assumes cache_key is always non-NULL..

Access node backdrop as vector

Minor change from 'custom-manipulators' branch, avoid conflicts.

Add some missing VSE tooltips

Part of T51061

Differential Revision: https://developer.blender.org/D2664

UI correct use of "..." in the VSE

Usual i18n/message tweaks & fixes.

Fix T48996, bevel bad for certain in-plane edges.

Merge branch 'master' into blender2.8

Make 'set offset from cursor' group operator internal.

This operator relies on a rather specific context setup, so it shall not
be exposed to user in 'operator search' menu etc.

Based on D2528 by Vuk Garda?evi? (lijenstina).

Remove MinGW support

The Issue
=======

For a long time now MinGW has been unsupported and unmaintained and at this point,
it looks like something that we should just leave behind and move on.


Why Remove
==========

One of the big motivations for MinGW back in the day is that it was free compared to MSVC which was licensed based.
However, now that this is no longer true we have basically stopped updating the need CMake files.
Along with the CMake files, there are several patches to the extern libs needed to make this work. For example, see:
https://developer.blender.org/diffusion/B/browse/master/extern/carve/patches/mingw_w64.patch

If we wanted to keep MinGW then we would need to make more custom patches to the external libs and
this is not something our platform maintainers are willing to do.

For example, here is the patches needed to build python: https://github.com/Alexpux/MINGW-packages/tree/master/mingw-w64-python3

Fixes T51301

Fix T51637: Mesh Tools - Noise Button Crashes.

Logic behind which mtext to use from material was broken here... Though
ultimately that whole tool could probably be deprecated or reworked!

Release wasn't building, limit debug scope

CustomData: assert on bad arguments to free

Assert the index is in-range for the layer type.

Add automated ctest for complex merge in Array modifier.

See also T50851.

Fix T50851: Array modifier generating invalid geometry.

We had handling of fully duplicated polygons already, but... absolutely
nothing to sanitize partially merged polygons! This were giving us
totally invalid geometry, with duplicated vertices in single poly,
invalid edges, etc.

Now we do check for invalid loops inside polys, and generate new edges
as needed to get only valid polys.

For some reason this was a nightmare to get running fully OK, playing
with old and new indices is really, really mind breaking.
