Allow loading modules by 'load-file'

* src/lread.c (Fload): Call 'unbind_to' with 'Fmodule_load' as the
2nd arg, to avoid the "binding stack not balanced" error.
(syms_of_lread) <module-file-suffix>: New Lisp variable.

* lisp/files.el (module-file-suffix): Declare.
(load-file): Remove 'module-file-suffix' from
'completion-ignored-extensions', to allow completion on modules.

* etc/NEWS: Mention 'module-file-suffix'.

 ** Emacs can now load shared/dynamic libraries (modules).
 A dynamic Emacs module is a shared library that provides additional
 functionality for use in Emacs Lisp programs, just like a package

 A module should export a C-callable function named
 `emacs_module_init', which Emacs will call as part of the call to
