Subject: * gem_prelude.rb: new file for gem libraries.  currently empty.

* 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.
