Scot Breitenfeld cbff0315f3 Default versioned API functions to earliest version for older API settings (#6280) 
When a global API version is set (e.g., H5_USE_16_API), functions
introduced after that version now default to their earliest version
(version 1) instead of the latest. This prevents breakage when an
application uses an older API setting but calls functions that were
later versioned.
