Request for review: 8016046 (process) Strict validation of input should be security manager case only [win]

[Alexey Utkin]

Hi,
Please review the fix.

Bug description:
     http://bugs.sun.com/view_bug.do?bug_id=8016046
     https://jbs.oracle.com/bugs/browse/JDK-8016046

The suggested fix:
http://cr.openjdk.java.net/~uta/openjdk-webrevs/JDK-8016046/webrev.00/

Summary:
     In absence of the Security Manager the verification procedure for 
the command-line was restored as before the JDK-8012453 fix. That 
suggests the ability of inline input/output redirection, piping, 
simultaneous launching of several programs by single command, lost 
spaces and etc.
The extended verification procedure is activated in presence of the 
Security Manager or installing to "false" the 
"jdk.lang.Process.allowAmbiguousCommands" Java property.

Regards,
-uta
