configure.in: Test for availability of putc_unlocked, fputc_unlocked, and fputs_unlocked. 

* configure.in: Test for availability of putc_unlocked, fputc_unlocked,
        and fputs_unlocked.
        * configure: Rebuilt.
        * system.h: If the *_unlocked functions are available use them
        instead of the locked counterparts by defining macros.
        * config.in: Regenerated.
