RFR: [8036088] - Thread-unsafe strtok() is used to parse the list of overrides

[Ivan Gerasimov]

Hello!

The strtok() function is used in 
./windows/native/sun/net/spi/DefaultProxySelector.c.
This function is not thread safe, so it may potentially cause a problem.

The failure in this particular place would be very unlikely, because 
this code should be executed only once during initialization.
Therefore, no regtest provided.

The fix would be to use a thread-safe equivalent, which is strtok_s() 
under Windows.

Would you please help review this simple fix?
