GP Sculpt: More WIP work to try and get this randomise brush working

So it turns out that the screenspace-to-3d math is a lot more convoluted now
than would be initially obvious. The brush is now behaving a lot better now
in that it somewhat does what is expected. The results aren't really what we
really want yet, so some more experimentation is still needed.

Fix merge conflict caused by own smartness failing

Move display code and tangent calculation to loops WIP patch by Campbell

Convert tangent layer and baking to use looptris. This is WIP code
to make sure all blender uses tangents generated from loops.

Fix several issues, add a quick and dirty new action in Outliner to remap IDs.

We have to take care of Object->data aside from main foreach loop, since we can
only replace that pointer if object is **not** in Edit mode!

Also, added a "Remap" action to ID context menu of outliner. This is **very far**
from nice and pretty code/feature, but it allows to quickly test the code.

Only did very quick tests with meshes so far...

Fix some dummy mistake, add simple RNA callback to 'remap' IDs.

Also, added Object.data to BKE_library_foreach_ID_link(), wonder if there was a good reason
for this to not be here???

Add main 'ID remap' function.

Theoretical code, compiles, but needs to be tested!

ID remapping: first step - modify some editors callback to not only support ID freeing, but also ID remapping.

This seems to be OK, but will obviously need much more testing - and is useless as-is, we need
the big ID remapping code itself still.

Also, Nodetrees' remapping of Scene IDs is still TODO, not sure yet how to do this.

OpenSubdiv: Some last minute improvements

- use utility function to define shader's input, output types
and number of vertices.

- Make sure #version 150 is never used if blender is built
without OpenSubdiv.

OpenSubdiv: Fix for #version being defined multiple times for geometry shader

GP Sculpt: Buggy attempt at building a "randomise" brush

This currently just sends the points off screen. We need another approach.

Make gcc 5 more happy

Fix search menus being drawn transparent

Reverts rBb22061e98946a. Don't think it's worth using an extra widget type for this.
