fix for freetype download link and llvm/clang header harvesting

Merge branch 'master' into functions

Fix T55589, T60967: Windows pen pressure issues at start/end of the stroke.

The new implementation uses WM_POINTERDOWN, WM_POINTERUP and WM_POINTERUPDATE
and the pointer API to process stylus events. This avoids the delays that comes
with the WM_MOUSE and WM_xBUTTON events. The implementation should work on
Windows 8, and Windows 10 with both legacy and new pen interaction.

It also changes how the pressure is reset when the Windows Ink implementation
is enabled. The previous version reset the pressure to full when the pen left
the screen, however for some hardware implementations this allowed a small
window where Blender may process the final move event and read the pressure
as full leaving a dot on the last event.

Windows: use Wintab by default if it's available and a device is detected.

Previously Automatic tablet API mode would handle both Windows Ink and
Wintab events. This is unpredictable and causes problems with the fix
coming in the next commit.

Instead assume that in most cases where Windows Ink is desired there
will be no Wintab. If that's not the case, it can be adjusted under
Preferences > Input > Tablet.

Multires: Make topology cache to work with copy-on-write

Allows to preserve topology cache even when copy-on-write is
fully re-copying the object. For example, toggling edit mode
in and out does no longer causes full topology to be re-created.

Fix export_obj_cube test.

Verified that current export files for all_quads.blend are good,
then updated expected MD5 hash to match current files.

Fix T62780 , T59802, T57648: fullscreen window issues on Windows.

This fixes popups and preferences appearing behind the main window, as
well as flickering artifacts when Blender is in fullscreen.

UI: remove close button from Windows console window.

This way you can't accidentally close Blender when toggling the console
window to be visible. When Blender is started from the command promt the
close button remains.

Fix T63217: Curve Modifier skipped in Cycles

Only mesh objects have all modifiers applied on the evaluated
object's data, other object types are to apply modifiers during
the conversion process.

Fix T62939: Incorrect cursor position when exiting UI slider

Differential Revision: https://developer.blender.org/D4629

UI: Fix odd behavior in region sizing, simplify code

* When resizing sidebars, don't collapse when the region becomes too big but
instead clamp the region size to the available space.
* Fix clicking the tab to expand sidebars no working if the sidebar is too
wide to fit. Instead make it less wide so it does fit.
* Fix incorrect limit on tool properties region height, for example in the
file browser.

deps_builder : copy llvm headers to lib folder.

Were not needed previously, but the functions branch needs them.

Fix T62817: Can't drive modifier property with another one

Random place in the modifier stack can not be referenced,
so it doesn't make sense to sue GEOMETRY component as a
FROM operation.

So now drivers on modifiers are driving GEOMETRY component,
but are using PARAMETERS as a source for variables.

use cache to avoid building the same function ir twice

GPencil: Implement custom channel color in Dopesheet

A new parameter in the layer adjustment panel allows to define the color of the channel in Dopesheet.

This is needed when there are a lot of layers.

See D4623 for more details.
