Fix T64430: Removing objects from sub-collection doesn't update instances of parent collection.

Collections are a tad annoying with all their caching of objects... When
we modify content of a children collection, we need to tag DeG for CoW
update of all of the ancestors.

For now keeping that recursive tagging helper private, but would not be
surprised if we found more similar cases and needed to expose it to more
code...

Fix (unreported) message wrongly using IFACE_ for its translation.

`IFACE_` is for short strings always shown in UI (like labels of buttons,
menu entries...). Every thing else, especially when more than a couple
of words, must use `TIP_`.

Fix T64608: DOF Focus object, not linked to new copy, Scen "full_copy".

Note that there are probably many other similar cases... This code is
really legacy, should use library_query helpers and other modern
BKE_library code instead of doing its own dirty cooking...

Edit Mode: Fix face alpha being too strong in xray mode

This make the xray & wireframe follows the same style as the solid
mode.

Fix T65406 Edit Mode: Edge selection is below wireframe overlay

This was due to a double offset of the wireframe. We also reduce
the wireframe offset. The look of the wireframe overlay changes
a little with on distant wires.

FFmpeg: Fix integer overflow when writing custom FPS with high denominator

FFmpeg uses a fraction of integers to indicate the frame rate, whereas
Blender uses `int / float`. When a custom frame rate is used with
non-integer base, the FPS and Base settings were multiplied with 100000
before passing to FFmpeg as `int`. This could overflow when a high
enough FPS setting was used, which is the case when importing a video of
almost-but-not-quite-integer frame rate into the VSE. The overflow
caused FFmpeg to return an error "The encoder timebase is not set",
which is rather cryptic for users.

The new solution is to take the max int and divide that by the frame
rate, and use that ratio to pass to FFmpeg. This won't overflow, and
thus allows exporting arbitrary frame rates.

OpenGL Render: Fix crash when using audio

Was very easy to reproduce by rendering sequencer with sound strip.

Need to use evaluated scene to open movie handle, since that is the only
scene which has proper sound handle with everything else attached to it.

Sound: Fix missing sound sequences length update on FPS change

Sound: Fix queries of sound info

A lot of areas were querying sound information directly using audio handle
which does not exist on an original sound IDs.

This change basically makes it so it's possible to query information about
given sound ID, without worrying about whether it's loaded or not: if it is
needed to load it first it happens automatically (no automatically-opened
handles are left behind though).

While this seems a bit extreme to open files on such queries it is still
better than the old situation when all sound handles were opened on file
load, no matter if it's needed or not. Besides, none of the changed code
paths are performance critical, just handful of tools.

Fix T65671: Armature X-Mirror inconsistencies

Apparently the `rna_Armature_editbone_transform_update` function was incomplete because it didn't copy all mirrored transform values.

I also noticed that the same logic seen in `rna_Armature_editbone_transform_update` is also seen in `ED_armature_edit_transform_mirror_update`.
So the solution is expose and use that logic that updates a mirrored bone. Thus deduplicating and fixing T65671.

Fix T65702: Load factory erases setting without confirmation

It could be argued this was correct behavior, since auto-save
defaults to 'on' nevertheless, auto-saving settings once
the user has disabled auto-save can lead to accidents.
