Fix Filebrowser Blender ID filter

When the filtering option was disable we should see all the datablock types.

Differential Revision: https://developer.blender.org/D6033

Fix image undo restoring float/byte tiles into the wrong buffer type

This also resolves the (unlikely) issue of undo having uninitialized
zbuf data, now it's cleared instead.

Docs: clarify writefile.c format text

Fix incorrect brush falloff flag use

Harmless currently since they're the same value,
would fail if other options were added.

Fix: First item in File Browser can't be renamed

Stupid mistake in 5edfde58fe60.

Py API doc generator: more tweaks to adapt to new release process.

Now we also create a 'version' symlink for master.

UI: Add renaming to Node and VSE strip context menu

We should have that consistently everywhere the operation is available.

Fix autokeyframe not working on bones mirrored bones

The previous code for this didn't work as the MIRROR bone flag would be
cleared before the autokeyframe code was run.

Py API doc generator: tweak to handle new release process.

We need to handle beta stage in a specific way, since it's no longer
master, but not yet 'real' rc/release stage...

For now, only point to version dir of the API doc, but no need to create
any symlink (that way, 'current' remain pointing to 2.80 release, while
'2.81' is no longer a symlink to 'master', but its own actual doc).

Update Py API link in help menu to point to version dir also in beta.

Now that we have beta and master in parallel, we cannot point to API doc
from master in beta builds of incoming release anymore.

File Browser: Add F2 shortcut to rename files

Previously, we used Ctrl+Click for renaming, but since that shortcut is
now consistently used to add items to the selection, we can't use that.
In other cases we switched to F2 now, so it makes sense for the File
Browser too.
Further, AFAIK renaming was only possible through the context menu,
which makes it hard to discover in the right click select keymap (have
to press W).

Note that I had to do some internal changes to ensure the context menu
always acts on the clicked/hovered item, while the shortcut operates on
the active item. William and I agreed that this is likely the behavior
expected by most users.

GPencil: Fix unreported duplicated brushes

The eraser and fill brushes were duplicated due a bug introduced by versioning code.

Fix T70581: Node Wrangler output switching broken

When executing the node selection operator through Python, or in fact
any similar select operator with drag-all-selected support, the operator
was enabling modal execution, which should not be done in this case.
Reason was simply a wrong default for an internal property.

Fix T70787: Duplicating objects with custom property of type ID creates bogus links.

Note that the issue also affected animdata handling...

Checked all usages of the `BKE_libblock_copy_ex()` function, and
think never handling user count here is valid, although a bit risky
maybe. But other solution would be to add yet another copy flag, so
would rather go with that one for now.

Cleanup: Fix naming of a function

GPU: prevent assert for zero length arrays

This could happen with the build modifier.

macOS: add opus to FFMPEG_LIBRARIES

Cleanup: pep8

Merge branch 'master' into greasepencil-object

Cleanup: clang-format
