distinguish internal/ext. builds with FIO_INTERNAL
To distinguish between internal and external includes of
fio.h and other headers FIO_INTERNAL get applied only for
the fio (and gfio) internal build itself.
This helps to prevent double-declaration issues by making
ambigous declaration with common names coditional based on
the FIO_INTERNAL define.
