Windows test scripts don't escape commas properly

[ambv]

In Windows batch file execution, a comma is one of the magic parameter delimiters. To pass a comma as parameter data, you have to use string quotes around that parameter, like:

.\Tools\buildbot\test.bat -M33g "-uall,extralargefile" test_zipfile64

However, now the quotes become part of the parameter. Inside test.bat we employ some command-line parsing and shifting, which requires us to remove the quotes from parameters, if any, for the code to continue working.

This is doubly complicated by the fact that test.bat passes execution to rt.bat, which does similar parsing there. The fix is needed there, too.
