Slight corrections to the string formatting of autosave, thanks to
Campbell for the help!

Gooseberry request, append the file name to autosaves as well as the pid

Correct recent refactor (use generic callback)

Cycles: Add "Max Bounce" control for lamps

With this setting, we can limit the influence of a lamp to a certain amount of bounces.
0 = Only direct light contribution
1 = 1 light bounce

Fixed warning about redefining the __SSE__ macro in VS2013

Fix T42255: "Copy Constraints" operator has to tag the affected object
and pose for depsgraph.

Otherwise the update order can be incorrect until the next sort is
executed.

Editmesh: report a warning when fill fails

also prevent assert with zero normal

Debug: print output on --debug-fpe

in practice often we want to breakpoint here (instead of flooding output)
but its confusing the option does nothing in release builds.

Devs can comment out locally.

Simplify node frame detach operators, based on T34670 by @julien.

* The `NODE_OT_parent_clear` operator has been removed. This was a very
simplistic operator that detached every selected node, which is not very
useful in case of hierarchical frames. The `NODE_OT_detach` operator
only detaches the top parent nodes in the selection, keeping the
hierarchy of selected nodes intact.

* The `ALT+P` shortcut has been reassigned to the `NODE_OT_detach`
operator which replaces the previous `NODE_OT_clear` mapping with
similar behavior (also gives a menu entry shortcut now).

* Shortcuts for `NODE_OT_detach_translate_attach` have been removed, due
to crowded and messy keymap and unintuitive shortcut `ALT+F`. This macro
operator is still registered, in case hardcore users want to make their
own keymaps, but not mapped by default. Node keymaps may need some
redesign in the future for these things.

Code cleanup: Replace magic number with verbose name for math node operations

Should be no functional changes, just much less cryptic code.

Cycles: Don't check shader for volume when checking if camera is inside volume

Intersection code already ignores objects without volume closure so checking it
afterwards is not needed.

Fix T42411: Camera inside volume + particle dupli (object/group) doesn't work

The issue was caused by missing current object instance initialization after
object was ignored for instance push.

BMesh dissolve: enable use_verts for edge dissolve (by default)

Fix T42408: FSAA affects Cycles Image Compositing

Use FSAA settings only if current render engine is BI or GE/

That's for until we'll support FSAA in Cycles or other render engines.

Fix T42289: 'Make single user' not registered in history

Fix-for-fix ik-spline clamp existing files too

Fix T42445: Clamp flag has no effect on result value in Math and MixRGB shader nodes (Blender Render)

Quite striaghtforward implementation, with the only weird thing that for some reason
my video driver wasn't happy with calling the function "clamp" giving some weirdo
shader compilation error messages.

Called the GPU function clamp_val which can handle float and vec3.

Add utility macros to clamp all elements of 2,3,4 component vectors

Code cleanup: Replace magic constants with defines

From quich search didn't see where the flags are used apart from
RNA currently, but i might have missed something.

Cycles: Remove compatibility code for OSL-1.4

That code was mainly needed for the transition period, now we've
got all platforms updated to new OSL.

Plus there are some crucial fixes baking in the current upstream
sources which we'll need to have for the next Blender release.
