For internal use in libgcrypt we don't need a size argument.  For the
piblic API we should have one; we nearly always do this.  One exception
which comes to mind is gcry_md_read but this function just returns data
and does not take data.

Of course we could also switch back to s-expressions as used by all
other public key functions.  But your gaol is to have an asier to use
API than one where you first need to construct an s-expression and later
parse the result from it (and I agree with you here).
