Currently does not support copying of animation data. This would require copying of individual fcurves etc. between data block, which is not implemented yet.
Also it is currently possible to circumvent some constraints of the nodes, in particular for node groups (e.g. no groups inside groups, render layer not inside groups).
Previous attempt was not taking into account parent nodes of the group nodes (i.e. frames). The nodeFromView function should be used to convert between relative node location to absolute view space. Also added this in the node_add_node helper function, which is used in a number of operators for adding nodes in a specific location.
All node group operators which move nodes directly between bNodeTree->nodes lists now make sure the node names are indeed unique in their new environment (the node group tree or the parent tree).
1) For inserting into existing groups:
The 'Make Group from selected' (CTRL+g) operator shows a selection popup (like the object parenting operator), with options depending on the type of the active node (last selected):
* "New" -> regular operator, creates new group type with all selected nodes inside.
* "Insert" (only if active node is a group) -> adds all other selected nodes into the group.
Currently still prohibits groups inside groups in general, though would be technically possible as long as no actual recursion occurs (group containing itself).
2) For extracting from an existing group:
New 'Separate from group' operator (p), works similar to separating vertices/edges/faces from mesh. Two modes:
* "Copy" makes a copy of the nodes in the parent tree, but keeps the original group intact.
* "Move" removes selected nodes from the node group and adds them to the parent tree
By holding shift and "cutting" a node link a new reroute helper node can be inserted. This consists of a single socket that can be used to insert additional connection points into a link. This can be used to keep a connection point in the tree when deleting a node, or to control the path of long connections for layout cleanup.

TL;DR:
* Frame node gets more usable bounding-box behavior
* Node resizing has helpful mouse cursor indicators and works on all borders
* Node selection/active colors are themeable independently
* Customizable background colors for nodes (useful for frames visual
distinction).

This operator still had some built-in assumptions about the connectivity of input/output sockets (1-to-n in all current node systems). For future node systems (e.g. flow-based particles) and for general customizable nodes the operator is now fully symmetric and supports all kinds of connectivity limits (1:1, 1:n, m:1, m:n).
The operator data can also store a list of node links as opposed to a single link now, so that multiple links can be redirected at once. Holding the CTRL key when clicking a socket, all links from/to that socket are detached and can be moved to a different socket. This is useful for quickly appending a node without moving every individual link.
This was originally reimplemented as part of the socket selection feature, but since selecting a socket necessarily also selected the owning node, it messes with the manual user selection of nodes too much (and doesn't add any additional usability).
* Removed the struct_type identifier from sockets completely. Any specialization of socket types can be done by using separate collections in RNA and customized socket draw callbacks in node type. Sockets themselves are pure data inputs/outputs now. Possibly the sock->storage data could also be removed, but this will change anyway with id properties in custom nodes.
* Replaced the direct socket button draw calls by extra callbacks in node types. This allows nodes to draw sockets in specialized ways without referring to the additional struct_type identifier. Default is simply drawing the socket default_value button, only file output node overrides this atm.
* File output node slots now use a separate file sub-path in their storage data, instead of using the socket name. That way the path is an actual PROP_FILEPATH property and it works better with the UI list template (name property is local to the data struct).
* Node draw contexts for options on the node itself and detail buttons in the sidebar now have an extra context pointer "node" (uiLayoutSetContextPointer). This can be used to bind operator buttons to a specific node, instead of having to rely on the active/selected node(s) or making weak links via node name. Compare to modifiers and logic bricks, they use the same feature.
* Added another operator for reordering custom input slots in the file output node.
