433563 - Jetty fails to startup on windows - InvalidPathException

+ PathMatchers.isAbsolute() and .getSearchRoot() adjusted to not
  rely on Path object behavior differences between Unix and Windows
+ Updated StartArgs processing of --lib to automatically expand
  extra lib references prior to submitting them to the internal
  BaseHome for processing as pattern for paths.
+ Updated test cases for new behavior.
Merge branch 'master' of ssh://git.eclipse.org/gitroot/jetty/org.eclipse.jetty.project
Fixing bad EOL assumptions based on running OS (should be based on git checkout state)
