remove "externals" from the vm
* libguile/frames.c (scm_frame_external_link): Removed. * libguile/frames.h: No need to have the "external link" in the stack frame -- update macros to take the new situation into account. * libguile/objcodes.h (struct scm_objcode): Rename the nexts field to "unused". In the future we can use it for nlocs, I think. (SCM_OBJCODE_NEXTS): removed. * libguile/programs.h: * libguile/programs.c (scm_make_program): Expect the third argument to be a vector of free variables, not a list of free variables. SCM_BOOL_F indicates no free variables, not SCM_EOL. (program_mark): Adapt. (scm_program_arity): No more nexts. (scm_program_free_vars): Replaces scm_program_externals. * libguile/vm-engine.c (VM_CHECK_EXTERNAL) (vm_engine): No need for the "external" var. * libguile/vm-engine.h (CACHE_PROGRAM): Update for SCM_PROGRAM_FREE_VARS instead of SCM_PROGRAM_EXTERNALS. (NEW_FRAME): Update for new frame size, and no need to cons up externals. Yay :) * libguile/vm-i-loader.c (load-program): Update for scm_make_program. * libguile/vm-i-system.c (external-ref, external-set): No more. (make-closure): No more. (goto/args): No need to re-cons externals here. Update for new stack frame size. (mv-call, return, return/values): Update for new frame size. No need to reinstate externals on return. * libguile/vm.c (really_make_boot_program, scm_load_compiled_with_vm): Update for scm_make_program. * module/language/objcode/spec.scm (objcode-env-externals): Treat '() as #f, for the externals. Need to clean this up later... * module/system/vm/program.scm (arity:nexts): Remove. Rename program-external to program-free-vars.
