RFR: 8144220: UL does not support full path names for log files on windows

[Marcus Larsson]

Hi,

Please review the following patch to allow full path names for log files 
on windows.

The full path to files will on windows contain a colon (from the C:\ 
part), and there used to be no way to avoid that colon from being parsed 
as the delimiter for the next -Xlog: option. With this patch it is now 
possible to avoid this by giving the path within quotation marks, for 
example: -Xlog:all:"C:\out.log". Any colons within quotes will not be 
parsed as delimiters for -Xlog.
