move module and meta inside programs' object tables
* libguile/programs.h (struct scm_program): Remove the module and meta
fields.
* libguile/programs.c (scm_c_make_program): Add a new argument, `objs'.
If it's a vector, we'll look for the module and the metadata in there,
instead of having them in the scm_program structure.
(scm_c_make_closure, program_mark, scm_program_meta)
(scm_c_program_source, scm_program_module): Adapt to the new program
representation.
* libguile/objcodes.c (scm_objcode_to_program): Pass #f as the object
table when making the program.
* libguile/vm-engine.h (CACHE_PROGRAM):
* libguile/vm-engine.c (vm_run): Rework to use the simple vector API for
getting the current object table. Call the helper,
vm_make_boot_program, to make the boot program.
* libguile/vm-i-loader.c (load-program): Set the current module and the
meta in the object vector, which we pass to scm_c_make_program.
* libguile/vm-i-system.c (toplevel-ref, toplevel-set): Adapt to the new
program representation.
* module/language/glil/compile-objcode.scm (codegen): Clarify.
