fix for [#28581] Rip Tool Gives Strange/Bad Results

Note that this just comments a check which I couldnt see any reason for, both edge split modifier and rip tool seem to work ok without it. so left the code in with an '#if 0'

some edits to make the split code easier to read, replace "j ? (i+1) % f->len : i" with a variable since its re-used so much, no functional change.

svn merge -r40000:40179 https://svn.blender.org/svnroot/bf-blender/trunk/blender

picky formatting edits - no functional changes.

fix [#28635] Mirror Modifier - Clipping still active when modifier is disabled

Fix for a crash reported (four months ago!) by bupla, thanks!

Fixes #28599: Wrong re-assigning of layers in RenderLayer comp nodes when deleting a render layer.
Also added the check of comp nodetree of all scenes, as others might also use that scene in their compositing!

correct bad maximum value, for wile-loop node, outside the range of a short.

fix for typo in bevel code.

remove redundant casts

Cycles: fix crash with group node sockets that don't connect to any node
inside the group.

fix for error linking opencollada on linux.

Fix [#28614] Collada Exporter does not export Ambient term
reported by Steiner Bernhard

ma->ambX is calculated only on a render, so instead of relying on those values compute them manually.

Cycles:
* Fix missing update when editing objects with emission materials.
* Fix preview pass rendering set to 1 not showing full resolution.
* Fix CUDA runtime compiling failing due to missing cache directory.
* Use settings from first render layer for visibility and material override.

And a bunch of incomplete and still disabled code mostly related to closure
sampling.

use vector size and const args where possible (no functional change)
