Merge branch 'master' into blender2.8

New API function to call an existing menu

Thanks Campbell Barton for the help and review.
This is for Blender 2.8, so we are not using this function yet.

Missing from last commit

Fix T53632: Objects outside scene shown in popup

Only show objects in current scene when not pinned.

This commit adds a filter argument to id-template
since we may want to filter by other criteria.

Fix T53678: Smart Project UV margin ignores units

Fix an error on last commit

`count` here is multiplied by 4.

Fix crash when you change the curve resolution in Edit Mode of the Blender Render engine

Same problem as previous commit, but now in `drawobject.c`.
Also added a comment to the equivalent line in `draw_cache_imp_curve.c`.

Curve Edit Mode: Fix crash when the U-resolution of the curve is changed

`normal_len` did not follow the value of the loop that is executed to add the vertices, being different from the vbo size

Fix: MSVC2013 compile problems with the "inline" keyword

Cycles: CUDA support for rendering scenes that don't fit on GPU.

In that case it can now fall back to CPU memory, at the cost of reduced
performance. For scenes that fit in GPU memory, this commit should not
cause any noticeable slowdowns.

We don't use all physical system RAM, since that can cause OS instability.
We leave at least half of system RAM or 4GB to other software, whichever
is smaller.

For image textures in host memory, performance was maybe 20-30% slower
in our tests (although this is highly hardware and scene dependent). Once
other type of data doesn't fit on the GPU, performance can be e.g. 10x
slower, and at that point it's probably better to just render on the CPU.

Cycles: make CUDA code a bit more robust to host/device alloc failures.

Fixes a few corner cases found while stress testing host mapped memory.

Layers/Collections: Fix crash when deleting collection

If the collection to be deleted has a nested collection that is directly linked
to a view layer, we were getting a crash.

Layers: Fix operator_context unittest

This was broken since 70cdc8412c478b when we changed the requirement for context
scene collection to be part of context view layer.

Layers: Fix collection_rename unittest

This was broken since c9cb5dc3dab0af when we supported same name for
non-sibling collections.

Outliner: Master Collection always expanded

This is part of T53495.

This makes sure the master collection is always expanded and you don't even get
the expand/collapse icons for it.

This is only for the Collecions (currently Master Collection Tree) option, not
for active view layer.

Outliner: Always show the master collection on top of the tree

This reverts commit 0d0d68d39dad8e14b80489bc28d591fc6eff5f21 with extra changes.

This is part of T53495.

Outliner/Collections: Don't link a collection after creation
