RFR(S): 8214773: Replace use of thread unsafe strtok

[David Holmes]

Hi Nils,

Can you just define one version in os_posix.cpp and one in os_windows.cpp?

This per-os function really seems like overkill in this case. You could 
just add a Windows specific #define to convert strtok_r to strtok_s.

Thanks,
David
