* * boot-9.scm (resolve-module): New optional parameter that
controls whether autoloading is attempted or not. Default is #t.
(process-define-module): Don't autoload the defined module.
(try-module-autoload): Don't autoload the directory modules.
* * boot-9.scm (process-define-module): Ensure that the-scm-module
is last in the `uses' list to allow shadowing builtin
bindings. All :use-module options are added in the order they
appear in the arguments but before anything already on the list
(such as the-scm-module).
