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

[gerard ziemski]

Hi all,

Please review this revision 2 of a cleanup, where we remove 
JDK_GetVersionInfo0 and related code, since we can get build versions 
directly from within the VM itself.

The rev2 differs from rev1 in that it's simpler due to JDK-8234185, 
which was just checked in yesterday. Waiting for this fix to go in 
first, allowed us not to have to delete the jdk_util.h file, which in 
turn means that we don't have to touch all those files that used that 
include.


bug: https://bugs.openjdk.java.net/browse/JDK-8223261
webrev: http://cr.openjdk.java.net/~gziemski/8223261_rev2
tests: passes Mach5 tier1,2,3 (another tier1,2,3,4,5,6 in progress...)


cheers
