This change adds a new interface DSL for specifying objects (with methods) and interfaces (that expose objects, and optionally have their own methods). Significant changes: - Add the new scripts/definitions Python module to parse the DSL - Add the new definitions directory containing DSL definition files - Use cog to generate syscall-related code in kernel and libj6 - Unify ordering of pointer + length pairs in interfaces
