code cleanup - commant/remove unused vars and reduce scope.

Merging r39693 through r39989 from vgroup_modifiers branch into trunk.

Fix for value node limits.

The value input nodes (like rgb input nodes) use the output value out their first socket for the button value. This needs explicitly set range limits to allow meaningful user input.

Merging r39948 through r39988 from trunk into vgroup_modifiers.

fix for screw modifier - was clearning all faces, CDDM_calc_normals was overwriting the mface array because it re-tesselated polygons.

svn merge -r39951:39986 https://svn.blender.org/svnroot/bf-blender/trunk/blender

use Py_ssize_t rather than int when dealing with list sizes (original patch from Fedora but applied changes elsewhere too), also replace PyList_Size with PyList_GET_SIZE where typechecking is already done.

Split off scene export code.

BGE fix: ignore sounds that cannot be opened instead of crashing. ;-)

Fixed potential crash in NodeTagIDChanged. Discovered after merge trunk
into tomato where there were no check for tree before calling this function.
Old design worked fine with this.

Mark some arguments as UNUSED.

Cycles: set minimum required boost version lower.

Node merge: fix crash loading files with unknown nodes (e.g. cycles files).

Enabled the 'Layout' node category, currently only containing the 'Frame' node. Both the category and the node could be renamed as needed. The frame node is largely experimental and not totally useful yet, but much asked for, so can't hurt to let people try it out.

Fix missing warning message when reading files that are not forward compatible,
it seems this never worked in 2.5.

Fix screen/scene browsing in info header not working right, mistake in code cleanup.

Node merge: some forward compatibility code to avoid crash loading files with
node groups in older version, and to keep unconnected/default socket values.

Fix for node group add menu, groups from old files wouldn't show up there.

Reason was that node trees are now associated to specific node types (NODE_GROUP in particular) by the ntree->nodetype id.

Fix for multiple parallel group node executions.

This would previously break because begin/end functions for each tree type still have some checks of the ntree->execdata pointer in them, despite the intended use of execdata instances instead of trees themselves for execution data storage. This is an artifact of the old execution system that required these checks to be made in the functions to avoid multiple execution of top-level trees. Now these functions take an additional argument, so group nodes can prevent them from setting and checking the nodetree->execdata pointers.

Tidying up
----------------------------------------------
Comments and an unused define removed from last
commit.

Turned back on restricted deselect
----------------------------------------------
Fixed restricted deselect for edge select. Not
sure if face deselect is working properly, will
follow up with any reports on the tracker.
