Fix T66862: crash with mirror modifier applied to curve object

Fix T66999: Blender creates new cache for particles with step 10 instead 1

Update the default init step values to be the same for all caches.
This is actually a small hack as these values are not used on the
creation of the first cache. But the default init value is 1, so this
will not be noticeable anymore.

Fix T66944: Rigid Body Constraint in duplicated collection is not added to RigidBodyConstraints collection.

We only had a very limited, specific handling of that in collection
duplication code, but this has to be handled at a much more general
level in Object copy code itself, since it makes no sense to duplicate
rigidbody object data without adding new copy to relevant rigidbody
collections...

WARNING: This is a fairly risky rework of rigidbody handling logic
when copying an Object data-block. It is *NOT* considered safe enough
for 2.80 release.

I tried to take into account copy flags to not mess with other IDs
(collections) when we are copying outside of Main, and also not do deg
tags when this is forbidden, but risk of something going wrong here is
too high...

Fixed crash when adding/removing custom normals from pinned mesh

When a mesh is pinned in the properties panel, Blender crashes when you
click the "Add Custom Split Normals Data".

The code calls `ob = ED_object_context(C)` which returns NULL when the
mesh is pinned in the properties panel, causing a segfault when trying
to get the mesh via `ob->data`.

A new function `ED_mesh_context(C)` avoids this by first checking
whether a mesh was pinned in the context. If not, it checks the pinned
object's data. If that's not there, or it's not a mesh, it returns the
active object's mesh. Finally it returns NULL if there is no active
object, or if the active object is not a mesh object.

fix T66899: Collada: Shininess/Reflectivity not handled correct

Fixed: The Collada Exporter only supports export of
Lambert Shaders. But Shininess is not supported with
Lambert Shaders. The exporter must not add Shininess
to the Shader data!

Fixed: The Collada Importer adds an illegal value of -1
for reflectivity when this parameters is not defined in
the imported collada data. Now reflectivity is only
set when the import data contains a valid value.

Discarded: The Collada Importer handles shininess in a
dubious way. I have discarded import for now.
This needs to be reworked carefully in 2.81.
