. Allow users to force the file system provider to be the BSD file system

  provider.  This is helpful when users also wish to force os.name to a
  different value (e.g. Linux) but not being forced to also use the
  Linux file system provider.  This can be done by defining the property
  java.nio.file.spi.DefaultFileSystemProvider.

  This patch differs from the submitters in that the range of values are
  restricted to the current known defaults.
