[CHEF-489] refactor require()s so files don't double load

* For now, had to disable some explicit requirements. These are marked
  with CHEF489TODO
* rejiggered Chef::Platform so it hides all of the constants for
  providers in a method call. This is only sustainable if we give up on
  explicit requirements for Chef::Platform or place restrictions on
  where it can be required from.
* created providers.rb resources.rb and mixins.rb which are just a bunch
  of requires for the various types of files
* All tests pass on Ruby 1.8
* 110 test failures on Ruby 1.9.2 HEAD, mostly around String#each not
  existing any more, and implicit type conversions that no longer occur.
