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.

* common.mk: generate ext_prelude.c by prelude.rb and gem_prelude.rb.
ruby (not miniruby) is linked with ext_prelude.o instead of prelude.o.
* inits.c (rb_call_inits): don't call Init_prelude.
* ruby.c: support --disable-gems option.
(ruby_init_gems): new function to define Gem::Enable and
invoke Init_prelude.
(process_options): call ruby_init_gems just after
ruby_init_loadpath.
* tool/compile_prelude.rb: support multiple files.
