Merged the particles-2010 branch with node improvements into trunk. This branch adds mostly organizational improvements to the node system by renaming the node folders and files. A couple of internal features have been added too. Detailed information can be found on the wiki page: http://wiki.blender.org/index.php/User:Phonybone/Particles2010

#include "DNA_listBase.h"
Merge of the PyNodes branch (aka "custom nodes") into trunk. PyNodes opens up the node system in Blender to scripters and adds a number of UI-level improvements. === Dynamic node type registration === Node types can now be added at runtime, using the RNA registration mechanism from python. This enables addons such as render engines to create a complete user interface with nodes. Examples of how such nodes can be defined can be found in my personal wiki docs atm [1] and as a script template in release/scripts/templates_py/custom_nodes.py [2]. === Node group improvements === Each node editor now has a tree history of edited node groups, which allows opening and editing nested node groups. The node editor also supports pinning now, so that different spaces can be used to edit different node groups simultaneously. For more ramblings and rationale see (really old) blog post on code.blender.org [3]. The interface of node groups has been overhauled. Sockets of a node group are no longer displayed in columns on either side, but instead special input/output nodes are used to mirror group sockets inside a node tree. This solves the problem of long node lines in groups and allows more adaptable node layout. Internal sockets can be exposed from a group by either connecting to the extension sockets in input/output nodes (shown as empty circle) or by adding sockets from the node property bar in the "Interface" panel. Further details such as the socket name can also be changed there.

/**** Labels ****/
Make dynamic node labels possible as a registerable function 'draw_label' (simple 'label' identifier is already in use, need to avoid API breakage). This should simply return a string. The dynamic label can still be overridden by the user-defined node.label string.

void node_filter_label(struct bNodeTree *ntree, struct bNode *node, char *label, int maxlen);
Per-type node labels and customizable names. The label displayed in the node header is now by default the node type string. A custom label callback can be implemented to display more detailed information. This is currently used by group nodes, which display their internal tree name, and math, vector math, mix and filter nodes, which use their internal operation sub-type. Also the node tree selection/naming box for groups is now displayed only on open groups, to make it clearer that this is the internal type of the group and get a cleaner main tree.

Node callback for handling link insertion and swapping of occupied inputs. Nodes have a feature for moving existing links to unoccupied sockets when connecting to an already used input. This is based on the standard legacy socket types (value/float, vector, color/rgba) and works reasonably well for shader, compositor and texture nodes. For new pynode systems, however, the hardcoded nature of that feature has major drawbacks: * It does not take different type systems into account, leading to meaningless connections when sockets are swapped and making the feature useless or outright debilitating. * Advanced socket behaviors would be possible with a registerable callback, e.g. creating extensible input lists that move existing connections down to make room for a new link. Now any handling of new links is done via the 'insert_links' callback, which can also be registered through the RNA API. For the legacy shader/compo/tex nodes the behavior is the same, using a C callback. Note on the 'use_swap' flag: this has been removed because it was meaningless anyway: It was disabled only for the insert-node-on-link feature, which works only for completely unconnected nodes anyway, so there would be nothing to swap in the first place.

/*** Link Handling */
void node_insert_link_default(struct bNodeTree *ntree, struct bNode *node, struct bNodeLink *link);
Internal node links are now cached in a per-node list, instead of being generated as a transient list that is returned from the callback and had to be freed by the caller. These internal links are used for muted nodes, disconnect operators and reroute nodes, to effectively replace the node with direct input-to-output links. Storing this list in the node has the advantage of requiring far fewer calls to the potentially expensive internal_connect callback. This was called on every node redraw ... Also it will allow Cycles to properly use the internal links for muted nodes, which ensures consistent behavior. The previous method was not applicable in Cycles because transient list return values are not supported well in the RNA and particularly the C++ API implementation.
