Fixup for view3d collection name drawing when no active object

Merge branch 'master' into blender2.8

WM: enforce descriptions being NULL or defined

Without this bugs slip through that don't null check the descriptions
since many were set to empty strings.

Cleanup: python doc-strings

Indentation & trailing space.

Add active collection to viewport "name" stats

Only visible when in object mode.

Most of the time we will have the active object not being a part of the active
collection. So it is important to clearly communicate what is the active
collection, so users know for instance where new or appended objects
will be added to.

Add active collection to stats bar

Only show the collection name when in object mode.
It is not relevant in any other mode.

Util to get collection UI name

Note we still have hardcoded IFACE_("Scene Collection") in the outliner.
I'm ok with getting of them as well, though no strong feelings here.

Fix tool keymaps not working properly after recent changes.

Not sure this is the best fix, but this should be working. Regardless it seems
good to tag active tool keymaps as such.

Keymaps: minor code refactor to abstract some events, no functional changes.

Keymaps: reload key configuration when changing select mouse.

For configuration scripts that want to change keymaps based on this setting.

Depsgraph: fix missing relations for drivers on ShaderNode properties.

Also fix duplicate driver to target relations due to a redundant line.

GP: Don't calculate fast drawing when playing

Keymap: code refactor to makes some events changeable with parameters.

No functional changes.

Keymaps: refactor loading of default keymap, fix bugs.

This refactors loading of key configurations to clear and refill existing
ones, rather than adding a new one and then removing the old one.

This fixes broken loading of non-default configurations after recent changes,
and prepares for future changes to make it possible to dynamically change
key configurations based on user preferences.

Fix crash when Python creates modal keymaps without items.

Fix T57708: Crash on Eevee rendering with SSR enabled.

Intel does not like dead code.
The driver for `Intel HD Graphics 4000` crashes in these cases.

GP: Fix wrong fill texture when draw primitives

GP: Fix wrong fill after subdivide

Py API Docs: Remove older GPUOffScreen example

I think this example does not belong into the api docs and certainly not in the place where it was until now.
Maybe this can become a template in Blender but personally I don't see much value in it as an "official example" because it is hard to see what is going on exactly.
There are a few other examples that show how to use the GPUOffScreen object now.
