While working to reduce startup time initializing properties, a pair of
improvements are proposed.
8185496: Improve performance of system properties initialization in
initPhase1 [1]
8213424: VersionProps duplicate initialization [2]
1) The overhead of providing default values in native is reduced by
applying the defaults
when first used and leaving the properties undefined unless there is
an OS supplied value or a -D command line argument
2) Two tests for properties are combined into a more complete test

Thanks for any comments and suggestions, Roger
