MXNet Extensions: custom operators, partitioning, and graph passes

Adds support for extending MXNet with custom operators, partitioning strategies, and graph passes. All implemented in a library easily compiled separately from the MXNet codebase, and dynamically loaded at runtime into any prebuilt installation of MXNet.
