Subject: * load.c (rb_load_path), vm_core.h (rb_vm_t): moved to VM.

* load.c (rb_get_load_path): returns absolute load path.

* load.c (load_path_getter): $LOAD_PATH getter.

* file.c (rb_find_file_ext, rb_find_file), ruby.c (push_include,
  ruby_init_loadpath): use the accessor.

* vm.c (rb_vm_mark): mark load_path.
