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.
The goal is to prevent assignment of temporary or evaluated meshes
to objects from the main database.
Majority of the change is actually related on passing reports around.
On a positive side there are more error prints which can become more
visible to scripters.
There are still possible further improvements in the related areas.
For example, disable user counting for evaluated ID datablocks when
assignment happens. But can also happen later on as a separate
improvement.

Tagging dirty was failing for UI scale, line width, hinting & others.
Checking for an update function means all update functions
need to tag preferences as dirty.
Since this check was added to prevent the active section marking the
preferences as dirty, only exclude this property.
- Resizable areas use 2D view bounds.
- Header uses the button bounds.
- A margin is added to avoid clicking between buttons.
- Region resize edges clamp to the 2D view bounds.

* It can be hidden by dragging it up/down.
* It can be at the top or bottom, independent of the header.
* It uses the color theme from the header.
* It does not change its color, when the area becomes active.
Currently, it is used in the text editor to display the file path.

Use this for the save confirmation dialog so it has a default action
when pressing enter which draws with a highlight so it's clear what the
default action is (the dialog was just closing before).

Support for RNA enum buttons that activate popovers when clicked.
This means we get useful tooltips, shortcuts and Ctrl-Wheel cycling
over enum items.
It also avoids inconvenient & slow access of enum values currently done
via RNA type lookups on the type to get the name & icon to use for a
regular popover button.

- Rename ui_but_find_active_in_region -> ui_region_find_active_but
- Remove ui_but_is_active (use ui_region_find_active_but instead)
- Re-order ui_but_* functions take the button as their first arg.
Mouse wheel on menus changes the selected item item which doesn't work
well for popovers since buttons aren't always stacked vertically.
