RFR(xs): JDK-8152329: jvm should treat the "Multi-Release" jar manifest attribute name as case insensitive

[Jiangli Zhou]

Hi Calvin,

Have you thought about using strcasecmp()? The globalDefinitions_visCPP.hpp defines strcasecmp to _stricmp. So compiler dependency is not an issue. We have existing code that uses strcasecmp() for case insensitive comparison.

// Non-standard stdlib-like stuff:
inline int strcasecmp(const char *s1, const char *s2) { return _stricmp(s1,s2); }

Thanks,
Jiangli
