Unify all-zero buffers; add fwritezero()

We have a number of all-zero buffers in the code.  Put a single
all-zero buffer in nasmlib.c.  Additionally, add fwritezero()
which can be used to write an arbitrary number of all-zero bytes;
this prevents the situation where the all-zero buffer is simply
too small.
