Prevent users to be able to override context engine

We expose engine as a string, yet context is dealing with Pointers. To prevent a crash
we may as well just forbid users to override it.

Experiment with adding output file meta data from render engine

The idea is to make it possible to report extra meta data from
render engine to the file writing. This way we can provide
additional information such as number of samples rendered by
resumable Cycles rendering so we can easily combine files back.

Currently only report number of samples from Cycles when rendering
a single render-layer scene. This is something what was required
here at the studio. We can easily extend that further.

Ideally we would also need to support non-string metadata, but
that's for later.

Stamp info: Use dedicated function to free up memory

This way it's more flexible to extend StampData structure

If an object is in any visible collection, the object will be visible.

MacOS: Use correct Cocoa protocol on any compiler

UI: replace UI_ITEM_O_RETURN_PROPS /w return arg

Means we can have a version of this function that returns the button
and avoids returning a struct that often isn't used.

UI: avoid double operator type lookup

Introduce "skip" in BLI_Iterator struct

This helps iterators prevent recursion.

Fix renderlayers UI removing the wrong renderlayer

Bug introduced on 1c4c28872721 (well technically in b48694639a).
We should not remove the renderlayer from the context, but instead the one that
is active from scene.

That said, the UI should make a distinction between the scene active render layer
and the one that is active in the UI (and that should be the one used when
removing it).

But for now this is at least more consistent for the users.

Add drag'n'drop-linking of material onto object in 3DView.

Probably needs to be reorganized a bit better, but basically working.
