Half-working workaround for image refcount in SpaceImage.

Our ID refcount handling is really flacky in many places, this is going to be a serious
issue for this work I'm afraid... :/

Simplify initialization of the deformedVerts variable.

No need to do the same thing in both code branches, the result is the same.

Moved the rather elaborate test for modifier sculptmode compatibility into own function.

Cleanup for mesh_calc_modifiers: Context and Iteration structs.

These gather most of the large number of local variables in that function,
in order to gain some clarity on their usage and scope.

Context is where immutable settings and global precomputed data is stored
during the computation. These values are initialized once and not touched
by modifiers.

Iterator struct holds the combined md/datamask pointers and some (hackish)
mutable data that gets updated during the process.

Where possible local variables have also been moved into narrower code blocks
to make the overall procedure less confusing.

Fix T46215: Explode modifier looses textures

Fix T46217: Make normal artifacts

Fix T46202: OS X (and Windows?) crash when going fullscreen.

Calling event handling recursively during window live resize is problematic,
the code wasn't designed to do that. Instead postpone event handling until
after live resize.

Update test to RNA API

prevent assert: select-linked UV delimit w/o UV's

Fix (unreported) Append/link code: All library datablocks could end with same name.

This was broken since ages I think, did not really hurt since we usually never use libs' names
to access them. Rather bad behavior however, breaking a ground rule of our ID system!

And no real reason to add new libraries to new (split) Main at all, libraries are
never considered linked datablocks, which means they should always be in 'main' Main->library list.

Not a regression, but should be included in 2.76 imho.

Fix T46159: OpenSubdiv does not always give same results as Blender own subsurf code with crease edges
