Bvhtrees take up a lot of memory space, reusing the common bvhtree of looptris to snap to vertices and edges is a good way to save memory.
Unfortunately we have a worsening performance in the snapping operation around 63% (addition to the original time).
But as we often do not need to build a bvhtree of loose verts and loose edges, we have an improvement in cache time :)
Since the CPU time of snapping operations (no matter how higth poly the object is) corresponds to less than 0.01% of all CPU time of a blender frame, that change is not really significant.
Snapping operations on a mesh in edit mode have not changed significantly.

Existing code checked pose/edit mode to check for transforming in an
objects local space.
This added many similar checks all over the code,
which leads to confusion.
Multi-edit caused a regression in UV transform since where UV's
had the object matrix applied by accident.
Now there is a boolean to use a local matrix,
this allows for any mode to have a 4x4 matrix
applied w/o adding mode specific checks everywhere.
With the clear separation between data and a state we need to make sure
operators and other areas are readingstate from evaluated datablocks.
Code-wise it means that all evaluated values are to be read from dataglock
which is owned by dependency graph, using DEG_get_evaluated_id() or similar
helper.

Applied similar fix to T54233 to get the "Record with NLA" feature working with
active action blending + influence settings. Extrapolation is explicitly ignored
though, as it shouldn't be used with this feature (i.e. it is already disabled
with the new strips and also on the animdata by default)
ViewRender was removed, which means we can't get the render engine for files
saved in 2.8. We assume that any files saved in 2.8 were intended to use Eevee
and set the engine to that.
A fix included with this is that .blend thumbails now draw with Clay mode,
and never Eevee or Cycles. These were drawn with solid mode in 2.7, and should
be very fast and not e.g. load heavy image textures.

The depsgraph was always created within a fixed evaluation context. Passing
both risks the depsgraph and evaluation context not matching, and it
complicates the Python API where we'd have to expose both which is not so
easy to understand.
This also removes the global evaluation context in main, which assumed there
to be a single active scene and view layer.

This adds initial multi-object editing support.
- Selected objects are used when entering edit & pose modes.
- Selection & tools work on all objects however many tools need porting
See: T54641 for remaining tasks.
Indentation will be done separately.
See patch: D3101
