The main problem with this would be the upgrade path for existing

1) Store cxx_stdlib per port in registry. With this, existing
   installations can be marked as outdated when the global setting
   is changed.

2) Honor cxx_stdlib in selection of archive_sites
   (similar to applications_dir and frameworks_dir)

3) Release base with changed defaults

4) Configure buildbots with libc++, publish binary archives in
   different directory and configure that for archive_sites in the
   ports tree.
