These are maintained by the various Linux distributions themselves instead.

Memory: add OBJECT_GUARDED_SAFE_DELETE like MEM_SAFE_FREE

Fix mistake in previous commit

While the behavior of this shortcut can be argued (it only works while
hovering the possibly invisible markers region), it was not my intention
to remove it entierly from the Graph and Sequencer Editor. Only wanted
to copy it.

Fix T73399: Crash trying to move the origin of an empty.

Empty objects have no obdata, so we need to check for NULL id...

Fix T66920: Shortcut Bind Camera to Marker in timeline not working

The shortcut was only registered for the marker region, although it can
be registered to the main region without conflicts.

Fix T73428: Editor type dropdown menu missing in VSE

Mistake in 6a49161c8c60, the tool-header region was not created when
creating a new VSE editor (as opposed to an existing one in some
workspace).

There was also no way to get the tool-header to show in such cases.

Fix HUD toggle ("Adjust Last Operation") missing in VSE

The `SpaceSequenceEditor.show_region_hud` property was not generated,
but accessed in Python.

Fix T71719: Unrelated menus open on hover

Logic to open menus on hover changed since 2.7x for convenience
switching between popovers in the top-bar.
This also made hover open menus in situations where it isn't useful.

Restrict this to buttons placed side-by-side.
