New bf library 'BlenVM' ("Blender Virtual Machine", BVM), as a general purpose runtime node backend.

This library provides a way to register modules and functions. Functions are simple
opcode-based descriptions of functionality (programs). They can be evaluated with
a simple interpreter using monolithic kernels, or could be compiled into more
optimized languages via LLVM or OpenCL.
