New stdio core. Should be more maintainable. Fixes a couple of bugs.

  Codepaths streamlined.  Improved performance for nonthreaded apps
  when linked with a thread-enabled libc.
Minor iconv bug and some locale/thread related startup issues fixed.
  These showed up in getting a gcj-compiled java helloworld app running.
Removed some old extension functions... _stdio_fdout and _stdio_fsfopen.
