Timer: Use explicit re-initialization on file load

Before this the timer API was relying on using a callback API to do
initialization when new file is loaded. This isn't how rest of Blender
works and it gets in a way because callbacks API is to be move to the
BKE level.

Use explicit call to timer API from where the file is loaded.

Cleanup: sort struct, file lists

cleanup some nonmovable and noncopyable functions

test if it builds on buildbot without alembic tests

test moving functions to bf_functions

test adding a virtual destructor to solve a linker issue

Was a wrong rename in rBaeb8e81f2741

Batch Rename: Rename Title Caps to Title Case

UI: Allow context menu in all file browser regions

UI: Allow file number shortcuts ouside main region

Makes the numpad + and - type of shortcuts to increase/decrease the file
number suffix work in the upper and lower bar of the file browser.

Had to add keymap handlers to the execute region for this to work.

Fix T69640: make update not working with Python older than 3.7

Edit Mesh: select interior faces now detects regions

The previous method only worked in simple cases where faces were
surrounded by non-manifold edges.

Now face regions surrounded by non-manifold edges are marked as interior.
Starting with regions most perpendicular to the surrounding geometry.

Fix T67756: File drag starts on file browser open

When the file browser was opened (from a temporary window since the file
browser redesign) using a button in the UI, under certain conditions
moving the mouse would trigger files to be dragged.

Note that this has been an issue before the new file browser design was
introduced, although under slightly different conditions.

Steps to reproduce:
* With factory settings, press F12
* Open a different image in the appearing Image Editor (not Render
Result)
* Make sure the window is not maximized
* Press N to open the side bar, open Image tab
* Click the folder icon there to change the image
* Change to thumbnail display type in the appearing file browser
* Cancel, click the folder icon again
Moving the mouse now would start dragging files in most cases.

The same issue could be reproduced in a similar way when installing
lights/MatCaps or HDRIs through Preferences -> Lights -> Install...

Fix T69634: GPencil:Cutter Tool removes unexpected strokes on another layer

The function was not checking the locked flag.

Cycles: add bump map shadow terminator softening term for diffuse BSDFs

This avoids artifacts for bump mapping and diffuse BSDFs, where the bump
normal deviates far from the actual normal.
