Class PlatformHelper
We had many changes in File.java, URLStreamHandler.java etc. to handle
path representations on different platforms (Windows/Unix-family).
Finally we'd like to collect all these ad hoc codes into this utility class.

INITIAL_MAX_PATH
public static final int INITIAL_MAX_PATH
On most platforms 260 is equal or greater than a max path value,
so we can set the initial buffer size of StringBuffer to half of this value
to improve performance.
isWindows
public static final boolean isWindows
beginWithRootPathPrefix
public static final int beginWithRootPathPrefix(String path)
This routine checks the input param "path" whether it begins with root path
prefix.
if not, return 0;
if yes, return the len of root path prefix;
--for Unix-family platform, root path begins with "/" and len is 1
--for Windows platform, root path begins with "drive:\\" and len is 3
endWithSeparator
public static final boolean endWithSeparator(String path)
This routine checks whether input param "path" ends with separator
isRootDirectory
public static final boolean isRootDirectory(String path)
This routine checks the input param "path" whether it's root directory.
--for Unix-family platform, root directory is "/"
--for Windows platform, root directory is "\\" or "drive:\\".
lastIndexOfSeparator
public static final int lastIndexOfSeparator(String path)
This routine returns last index of separator in input param "path",
and return it.
removeTailSeparator
public static final String removeTailSeparator(String path)
This routine removes from input param "path" the tail separator if it exists,
and return the remain part.
