Fully Node API compliant process.platform value.
Work to make Trireme work on Windows:
  Handling for paths where Node and Java are both trying to "help"
  Handling of the non-Posix filesystem for chmod, chown, etc.
Streamline fsync attribute reading.
Merge branch 'windows' of github.com:apigee/trireme into windows
Fix posix file attributes.
One more tweak of fs.stat handling.
Disable some broken tests.
Don't return the "real" platform if it's supposed to be hidden.
Merge branch 'master' of github.com:apigee/trireme into windows
Disable "hidden OS" test so the build doesn't break.
Exclude another test that is now re-enabled due to platform settings.
