Both object level and camera datablock properties animation did not work with
copy on write enabled.
The root of the issue is going to the fact, that all interface elements are
referencing original datablock. For example, View3D has pointer to camera it's
using, and all areas which does access v3d->camera should in fact query for
the evaluated version of that camera, within the current context.
Annoying part of this change is that we now need to pass depsgraph in lots
of places. Which is rather annoying.
Alternative would be to cache evaluated camera in viewport itself, but then
it makes it annoying to keep things in sync.
Not sure if there is nicer solution here.

Drawing hair weights read before the hair array start.
This code could be improved since it currently copy-pastes,
from do_particle_interpolation, but this would need larger changes.
For now just correct existing logic.
Sun is treated as a unit distant disk like in cycles.
Opti: Since computing the diffuse contribution via LTC is the same as not using the Linear Transformation, we can bypass most of the LTC code.
This replaces the sphere analytical diffuse computation as it gives a more pleasing result very close to cycles' AND cheaper.
Lights power have been retweaked to be coherent with cycles (except sun lamp with large radius where cycles has a non-uniform light distribution).
This is an improvement on the old spining quad method that was giving artifacts when the reflection ray was nearly aligned with the sphere center.
This might be a bit heavier but it's worth it.
Headers should not have operators as much as possible. The exception here is
for datablocks mode when you want to see the active keyset.
Edit menus on the other hand should be clearly distinct from the RMB context
menus. Edit menu options should be only the ones that apply to the entire
outliner, regardless of the selected element.
Context (rmb) menus should be related to the element you RMB on to invoke the
menu. I'm also taking this opportunity to start bringing the context menus
to Python. There is little reason not to, and it helps editing them (In this
case I'm doing it only for the Scene Collection one).

While the specific overflow issue may be fixed, loading the repro .blend
files may still crash because they are incomplete and corrupt. The way
they crash may be impossible to exploit, but this is difficult to prove.

One thing i'm not fully happy with is all this is_same_* functions. Need to
get rid of this by probably adding explicit entry/init/whatever nodes and
maybe making node criteria aware of whether key will be used as "from" or
as "to" node.
This leads to a ~3ms improvement of CPU time during drawing.
This prevent the rendering from being stalled waiting for the texture data to be transfered.
This is because certain part of the engine may require a blank framebuffer to bind textures to.
This is the case when using only array textures, unsupported by DRW_framebuffer_init().
By adding the ANIMFILTER_NODUPLIS flag to the filter it'll only be
processing each F-Curve once, which means we can remove while iterating.
This also solves a potential issue when a datablock has a driver and is
shared among multiple objects.
