Fix T40078: GLSL Lamp with OnlyShadow makes weird colors in object.

To prevent only shadow lamps from producing negative colors, shr->diff
and shr->spec should've been clamped to positive values after lamp loop.

Bake-API: replacing some MEM_callocN by MEM_mallocN

As suggested and reviewed by Campbell Barton. This is the most trivial of the cases. I will look if I can do it elsewhere in the bake code

Bake-API: Support for batch baking

When "Selected to Active" is not on, we bake all the selected objects.
This is the same behaviour we have for Blender Internal.

Dev note: I moved most of the validation tests to outside the bake()
routine so the function can be called in loop.

UI: fix for drawing textselect outside of button

also draw cursor even when there is a selection.

Followup to rB1973b17fce65, partially bring back GLSL lamp's previous behavior.

Using layer visibility in active render layer makes more accurate
preview but can cause problems in some cases:

GLSL lamps now ignore layer visibility if lock_camera_and_layers is
OFF or game engine is running. The material lamp group still works
unconditionally though.

Fix T40422: EdgeSlide works incorrectly with boundry edges

Proper fix T40156 Cycles Baking and applyRotation issues

This should be the final fix for the applyrotation issue. It baffles me
that the fix involves discarding the scale transformations for the
normals but it works so I'm happy with it.

Math lib: add negate_m3, negate_m4

Fix T39804: cycles smoke domain visible in rendering.

Transparent objects could become subtly visible by the different sampling
patterns for pixels covered and not covered by the object. It still converged
to the right solution but that can take a while. Now we try to use the same
sampling pattern here.

Fix T40408: world MIS + equiangular sampling giving unnecessary noise.

It's actually not possible to do equiangular sampling for distant lights, now
it reverts to distance sampling in this case.

Comments: Note direction in doxy args

Fix T39174 Bevel didn't maintain edge attributes.

When rebuilding the polygons that touch bevel-involved vertices,
need to copy the edge attributes from corresponding original edges.
Special treatment of corner segments, to maintain continuity of
smooth and seam attributes.
Another fix: if have four meeting edges, two opposite ones beveled
and the other two not, propgate the non-beveled-edges attributes
across the line that joins them (perpendicular to the bevel).

Cleanup: Use doxy for more structured comments

Sequencer: use escaping for sequence names

BLI_dynstr: add assert to check curlen is correct

Fix OpenCL compilation error in Cycles, when building without hair support.

Fix T39686: nused omp firstprivate variable sphdata in particles

OSX: fix T40413, automatic threads for compile throw wrong output

Fix T40414: Multiple input nodes in a group not working.

A node group can have multiple input nodes. In the compositor that means
each of the input sockets has to be connected to the linked outputs,
which is represented by a single link on the outside of the group.

Fix T40411: UI incorrectly permits changing materal_slots on linked obdata
