Fix memory leak calculating deform modifiers in edit-mode

This bug goes back to 2.80 but doesn't seem to have been reported.

Fix T77913: Incorrect handling of negative-scale bit in DRWResourceHandle

Fix T78112: VSE Sequencer/Preview crash after fullscreen

The region refresh callback wasn't called, which in the VSE ensures valid
region sizes and removes handlers of invisible regions.

Fix T67358: Compositor Disabled Node Config -> SegFault

The issue was caused by wrong conversion happening after some of the
proxies are removed. Easiest solution is to first remove proxies and
then add required converter operations.

Thanks Jeroen for the review!

Fix T77460: Easy to create cyclic dependencies in collections and crash Blender.

Cyclic check was not checking for collections instanciated by objects...

Fix crash when opening some old/broken .blend files after recent fix.

Now that `BKE_main_collections_parent_relations_rebuild()` is called
from readfile code, we need to make it resilient to potential NULL
master collection pointer in scenes.

Fix (unreported) critical mistake in Collection liblink code in readfile.c.

Prelimenary step to fix T77460.

Not sure how or when that thing was done, but since that call walks
around collections relationships, it's an utterly critical violation of
liblinking principles (code here should never, ever 'get outside' of its
own ID scope).

This was wroking so far only because code called through this function
(`BKE_collection_parent_relations_rebuild`) was only following parents
pointers (in `BKE_collection_find_cycle()`), which would be either valid
or non-existent.

But next commit is going to change that to also check collection's
objects instancing of other collections.

Fix T78172: Undo crash due to IDTemplate operations missing undo push.

This should be included in 2.83 as well.

Fix T77774: New undo code broken by 'make local' behavior.

This is actually a nice issue due to too much optimization...
* Making an ID local just reuse the linked one whenever possible, instead of
actually making a copy of it.
* Therefore, the collection containing that ID is seen as unchanged, since
the pointer itself remained the same.
* But on undo step, there is no way to reuse that local object, which then
gets deleted, and linked one gets re-created - at a different address.
* Collection, however, since unchanged, is not updated at all and thus keeps
reference to the to-be-deleted local object, instead of the linked one.
* Issue gets even worse with viewlayers, this leads to the crash.

To address this, this patch adds a 'virtual' update flags that does nothing
in update case, but will ensure that the affected IDs using the one made local
are properly detected as changed across the relevant undo step.

Note that the recalc flags were chosen mostly for a logical reason, and also
because they are already properly dealt with and cleared by undo code,
so this looks like the optimal solution.

Note: slightly ammended for 2.83, change should not have any effect in
practice.

Fix T77803: IK Degrees of freedom drawing glitch

IK degrees of freedom is rendered using wires and a solid sphere. The
solid used the wireframe drawing what resulted into drawing glitches.
This patch adds a new shader to draw the solid shape.

Fix (unreported) wrong size of UserPreferences' `dupflag` parameter.

Adding volume obdata option to `eDupli_ID_Flags` enum made it go beyond
the 16 bits of a short... Also, enums should typically be stored in
unsigned integers.

Fix T77915: Cycles OSL microfacet closure not working in custom shaders

The code to implement the newer closure in terms of the old one got lost in
the removal of our stdosl.h copy. Now implement it as a builtin closure.

Cycles: Refactor microfacet BSDFs to remove separate anisotropy code

Since the sampling and evaluation functions handle both cases anyways,
there's not really a point for keeping the distinction in the kernel,
so we might as well cut down the number of CLOSURE_BSDF_MICROFACETs a bit.
