Fix overlay being ignored in functions that read the depth buffer.

This corresponds to the behavior of blender 2.79.

DRW Manager: create and use new DRW_framebuffer_depth_read utility.

GPU: Create and use new GPU_texture_read_rect utility.

NodeEditor: Connect Viewer To Socket Selection

Request from the Spring team. When compositing the CTRL-Shift Click on a
node cycles the viewnode with an output socket. When you have many
render layers you spend time cycling to the desired socket. This patch
allows the user to CTRL-Shift Click on a socket to connect directly to
that socket.

DRW: minor optimization accessing the loop between a face and edge

Fix T62841: Hidden collection shortcut should be work in edit mode

This is a full revert of b6c61945aed51d86dc474df616761f9a25d71d09.

But ammended to include the object.hide_collection() operator to the
pose keymap as well.

While trying to expose the shortcuts to pose mode, I ended up exposing
them for all the modes. It is now only available for object and mode
modes.

Camera: change how the minimum near clip depth is set

do_clip wasn't working for its intended purpose,
replace with a simpler method.

RNA: Camera.view_frame no longer uses near clip for the camera frame

Use the same values used for drawing.

Style: describe code using comments instead of preprocessing directives.

Fix T62839 object scale changes normal map output in eevee

Was using the wrong vector length.

Fix/workaround some types of black dots in denoising with bright speculars.

This is not a real solution and colored dots still remain, just rejecting some
pixels that seem clearly wrong.

Volumetric textures were not freed when doing final rendering.

Cleanup: minor UI code changes

- 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.

Fix checkboxes being right aligned when property split is disabled

Cleanup: typo in variable name

UI: refactor queries into interface_query.c

interface_handlers.c is quite large (over 10k lines),
move general button utility functions into a separate file.

Fix incorrect hard limits on motion blur shutter time.
