This fix adds Pragmas to generate compilation errors, when using gcc, if calling a native system function instead of the os:: version of the function.  The fix includes changes to calls in non-shared code because it is cleaner than adding PRAGMAs and, for some cases, the os:: version of a function has added value, such as asserts and RESTARTABLE.  This fix slightly changes the signature of os::abort() so it wouldn't conflict with native abort() functions.  Changes to Windows code is left for a future RFE.
