* encoding.c (enc_get_default_encoding): removed.

  Generalizing rb_default_{external,internal}_encoding seems to be
  difficult. 
  default_external cannot be NULL even before detected. [ruby-dev:37390]

* encoding.c (rb_default_external_encoding): has its own
  implementation again.

* encoding.c (rb_default_internal_encoding): ditto.

* gem_prelude.rb: added notice.

* ruby.c (rubylib_mangled_path, rubylib_mangled_path2): uses locale
  encoding but not ASCII-8BIT.

* ruby.c (process_options): refers less to default_external.
