Cycles: Fix difference between SVM and OSL implementation of Normal node

SVM was normalizing the input normal, OSL did not. This lead to render
result differences across this shading systems.

Fix for wrong flip of Normal node Dot output for new shading system

It was wrong to use invert(), we need to multiply by -1 instead.

Fix T42472: Undoing/Redoing repeated transform operator gives wrong final matrix on objects with no geom data.

This hack should not be needed here, quoting Sergey, the actual issue comes from BKE_object_handle_update_ex,
which is calling BKE_object_where_is_calc_ex when it shouldn't.

Propper fix is depsgraph refactor topic, though.

Fix T42818: Cycles SSS passes are incorrect for SSS size of 0

This was caused by some internal optimization which evaluated SSS with
size of zero as BSDF but used different ID so the evaluation result
didn't appear in regular diffuse pass.

This lead to situation when SSS data was nowhere stored if the
size was zero.

Now SSS with zero size and close-to-zero sizes will be handled in the
same way from the passes point of view.

Fix T42748: Crash in subsurf, threaded access

Allocating the iterator from a BLI_memarena wasn't threadsafe.
Change the API to use stack memory for iterators.

Thanks to @mont29 for finding exact cause of the bug.

Switch to numpy 1.9 for windows platform

Fix numpy installation on windows+cmake

The was caused by numpy never unpackign because of no
dpependnecy of any targets from the unpacked numpy.

Tried making it so blender target dpeends on it, but for
some reason it didn't work. For now added dedicated target
for unpacked numpy. A bit dirty but much better than just
totally failing.

Fixes for compilation with msvc

MSVC doesn't like caling macro argument f when using float values
in the macro, it simply replaces the f in the float value with the
argument..

CMake compilation still fails because of 77785ce70807, numpy is never
getting unpacked.

cleanup: pep8

Sequencer: optionally show strip offsets

was disabled in recent sequencer refactor, enable with view menu option.

Correct last commit checking knife edges

Cycles: Code cleanup, typo

Knife: cuts along existing edges are now selected

This means cuts along existing edges don't have gaps in the selection.

Fixes T42616

Knife: rename vert & edge 'draw' to 'is_cut'

More logical for checking if the edge is a cut into the mesh.

Knife: fix edge aligned cuts, could add redundant verts

Smallhash: add support for iterating value pointers

also add reinsert function

Gooseberry request, circle select for graph editor

Fix T42857: Inconsistency between cache line visibility and ability to change frame from image space

Knife: test if an edge is on the face boundary

Was checking if an edges midpoint was inside the face,
giving random results (point-inside for an edge location).

Fix T42488: Knife (selected_only + occlude) failed
