prf.c: remove buffer limitation on precision and padding for floats
Even if the code used to limit the precision to the on-stack buffer
size, it was still possible to do:
printf("%f", 1.0e300);
which would overflow the stack and crash the program. Let fix this issue
and remove the precision limitation by recording the number of zeroes to
insert while converting the value and generating those zeroes only
when outputting the data.
