score: Add _IO_Printf() and _IO_Vprintf()
The previous vprintk() implementation had a questionable licence header,
lacks support for the 'z' and 'j' format specifiers, is not robust
against invalid format specifiers, uses a global variable for output.
Replace it with a stripped down version of the FreeBSD kernel kvprintf()
function.
The new implementation allows a low overhead rtems_snprintf() if
necessary.
Update #3199.
Close #3216.
