RFR: 8326090: Rename jvmti_aod.h [v2]

[Kim Barrett]

> Please review this trivial change that renames the file
> test/hotspot/jtreg/vmTestbase/nsk/share/jvmti/aod/jvmti_aod.h to jvmti_aod.hpp,
> and replace uses of NULL in the file.
> 
> The #include updates were performed mechanically, and build would fail if
> there were mistakes. All of the including files have already had their
> copyrights updated recently, as part of JDK-8324681. So the only interesting
> (for some minimal value of "interesting") changes are in the renamed file.
> 
> Testing: mach5 tier1
