BKE Library handling: add function to recompute usercounts of IDs.

This will be needed in undo/redo case, since we do not re-read linked
IDs, their usercounts become total garbage (especially in 'used by local
ID' cases)...

Sequencer: ensure Strip is the default active panel

Visibility panel: Use "toggle" keyword

No functional nor visual change.
This is a partial revert of 0910932e71d2.

The toggle option was introduced on 6640bcca7422.
This allow us to simplify the outliner draw code so it uses the icon as
defined in the RNA (as oppose to get the value there once again).

better cross platform exponent computation

more assertions in ArrayLookup

create ArrayRef from std::vector and std::array

cleanup SmallMap

UI: allow shrinking panel height to zero when open.

Currently if a panel becomes empty (draw simply returns), it stays
at the last non-empty height. This seems to be caused by some legacy
checks that may be completely obsolete, but the safest fix is to at
least allow resetting height when the panel is open.

Fix T64679: Missing dirty preferences tag

Use a default update function for user preferences that tags
dirty and redraws (if changed).

This avoids relying on button changes which fail in some cases.

RNA: add fallback update function

Use so we can have a default update function,
that doesn't need to be set for every property.

Cleanup: disambiguate rna_userdef_update_ui/ui_update

Cleanup: unused vars

DrawEngines: Depth Of Field Units

The unit system is designed for displaying and editing and not for
rendering. Eevee, Workbench and GPencil used these settings to convert
the focal length and sensor size to world units. Making depth of field
render differently with Cycles.

For now we will remove the scale in the draw engines to match cycles,
until we implemented a camera parameters specific scale.
