 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()

 The new implementation allows a low overhead rtems_snprintf() if

 Update #3199.
 Close #3216.
