This change finally adds capabilities to handles. Included changes: - j6_handle_t is now again 64 bits, with the highest 8 bits being a type code, and the next highest 24 bits being the capability mask, so that programs can check type/caps without calling the kernel. - The definitions grammar now includes a `capabilities [ ]` section on objects, to list what capabilities are relevant. - j6/caps.h is auto-generated from object capability lists - init_libj6 again sets __handle_self and __handle_sys, this is a bit of a hack. - A new syscall, j6_handle_list, will return the list of existing handles owned by the calling process. - syscall_verify.cpp.cog now actually checks that the needed capabilities exist on handles before allowing the call.
