Cleanup: Use node/socket pair keys more consistently instead of pointers.

Strict separation of input and output socket keys for clarity.

This avoids confusion regarding what socket keys are stored in maps etc.

Merge branch 'master' into object_nodes

Added basic semantics to the debug compiler by accessing node types.

Debug representation of generated bvm code.

A specialized compiler variant is added that turns generated code
into a graphviz diagram of the instruction lists.

Abstract virtual base for the BVMCompiler class.

This will allow different implementations of the compiler depending
on the intended target. This could be other bytecode formats (LLVM, SPIR),
but most imminently would be used for debugging.

Merge branch 'master' into object_nodes

Fix for broken pynodes: BVM functions in NodeTree must be optional.

Renamed map of basic blocks used for expressions.

Renamed FunctionInfo to BasicBlock, because that's what it is generally called in compilers.

Renamed the FUNCTION input value type to EXPRESSION for clarity.

'Function' is a more general term, the input is specifically an
'expression' because it returns a single value.

Implement more texture types.

This adds support for marble, magic, stucci, distorted noise, musgrave
and wood textures.

New vector math mode for vector length, patch by Philipp Oeser (lichtwerk).

Output values in node graphs are unused, removed.

In fact there is no per-output data in node instances at all, so the
OutputInstance data was removed entirely. All the connectivity and
value information is in the inputs.

Fix memleaks in refcounted data pointers on the bvm stack.

Fix for memleaks caused by un-freed Value instances, kudos to Kevin Dietrich!

These values are heap-allocated virtual classes, because general node code is
largely agnostic to data types. After adding values to a node (either as
default input values or per instance), care must be taken to free them when
the node type or instance is destroyed.

Merge branch 'master' into object_nodes

Reusable functions for copying a set of nodes and calculating node bounds.

Added an optional update callback for the configurable object node ID property.

'Make Group' operator (ctrl+g) to easily create a node group from selected nodes.
