Notes:
* Code in rendering and in game engine will still convert
tangents to a tessface representation. Added code that
takes care of tangent layer only, might be removed
when BGE and rendering goes full mlooptri mode.
* Baking should work discovered some dead code while
I was working on the patch, also tangents are broken
when baking from multires (also in master), but those
are separate issues that can be fixed later.
This should fix T45491 as well

modifier.
Since it was not ensuring dest has valid mdisp data matching new multires modifier subdiv level...
Also, fixed a bug in `multires_subdivide()`, which would crash when trying to
increase from level 0 (aka no subdiv) to > 1 (wrong check, trying to interpolate
when it should not). And added a few sanity checks.

This way it is possible to have viewport simplification bumped all the way up,
making viewport really responsive but still have final render to use highest
subdivision possible.

Problems were in the old multires loading system.
Actually, the sigsev itself was the easy part of the job (simply had to convert from tesselated data to polys/loops), but after that I was getting a horrible bunch of wild stray faces...
It finally turned out it was a mismatch in two different subsurf structs used while computing a mdisps layer from the multires DM, leading to getting complete random normals (null ones, NAN ones...), leading to complete dummy tangent space matrix, leading to absurds mdisps values...
Note: I also moved the copy of first layer's vertex and face data from old me->mr to mesh's v/fdata earlier in multire_load_old(), to be able to use general face_to_poly conversion function (later on we would have to do it by hand, the general function would erase our newly computed mdisps layer...).
Took me the whole week (something like 20h) to track this down: multires + subsurf = C nightmare!

When removing a skin or multires modifier, it skips deletion of the
associated CustomData layer if the object has any other modifiers of
that type. This check has been extended to all objects that use the
object's data.
Similarly, deleting higher multires levels and multires subdivision
will not update the maximum level of any other multires modifiers on
objects that link to the same mesh.
Note that modifier_apply_obdata() doesn't need any changes as it
does not allow applying to multi-user data.
Object joining has also been modified to synchronize multires levels
objects that share a mesh. This is needed because joining can
subdivide or delete levels in order to match the maximum level of the
join-from object to the join-to object.
