RFR (S) 8049300: jjs scripting: need way to quote $EXEC command arguments to protect spaces

[A. Sundararajan]

* javadoc comment for tokenizeCommandLine misses @throws IOException

* In nashorn project, parameters and locals (when possible) are 
explicitly declared "final" (project specific code convention). 
tokenizeCommandLine param and locals can be "final".

* Because there is no regression test, please add noreg-hard or 
appropriate label to the bug report.

The implementation of the $EXEC command would tokenise using a plain StringTokenizer, which splits a string at space characters regardless of quoting. The new implementation employs a StreamTokenizer and some extra logic to handle escaped spaces.
