RNA: check for 3D view overlay/shading

Use to calculate paths for the info window.

UI: Support status-bar hiding

Just like the top-bar, the status-bar can now be hidden/collapsed by dragging
its edge. We display a small line with the editor outline color then, so there
is something that can be dragged up to un-collapse the area again.
This collapsed state is not written to files yet.

UI: correct menu label comparison

Fix corrupt screen when splitting areas after collapsing top-bar

DNA: rename operator idname

Merge branch 'master' into blender2.8

Cleanup: remove unused context arg to menu

UI: support adding menu's to favourites

UI: move queries into interface_query.c

Merge branch 'master' into blender2.8

UI: Add 'interface_query.c'

Interface files are increasingly mixing up too much functionality,
add a file only to handle queries.

More functions can be moved/added here.

Merge branch 'master' into blender2.8

Cleanup: rename bmesh_queries -> bmesh_query

Other files with the same purpose already used 'query'.

Keymap: 2.7x, use fractions

Keymap: 2.7x uses spacebar for search.

UI: add operator search to edit-menu

While this is most useful to access from an active-region,
it's not discoverable without a menu entry.

Cleanup: use f-string

Cleanup: Move area geometry management into an own file

Area geometry management is quite complex and not easy to get into. We should
gradualy build an API that abstracts away this complexity.

Fix a number of small errors in area coordinate handling

For example collapsing the lower part of the topbar with 2x interface scale
would hide the top-bar header region. There were also more asserts when changing
window size and moving area edges afterwards (same assert as in T55298).
Fixes are similar to e626998a262ebe4f.

With all the recent fixes I've done, area geometry handling should be stable
again. Let's hope I'm right :)
