RFR (M) 8223261 "JDK-8189208 followup - remove JDK_GetVersionInfo0 and the supporting code"

[gerard ziemski]

Hi all,

Please review this cleanup, where we remove JDK_GetVersionInfo0 and 
related code, since we can get build versions directly from within the 
VM itself:

I'm including core-libs and awt in this review because the proposed fix 
touches their corresponding files.


bug: https://bugs.openjdk.java.net/browse/JDK-8223261
webrev: http://cr.openjdk.java.net/~gziemski/8223261_rev1
tests: passes Mach5 tier1,2,3,4,5,6


cheers
