Uses k_size as an signed integer
buf_incrwritepos() and mp_to_unsigned_bin() functions use k_size as signed
integer argument.
k_size is also used in an assertion that compared it to curve_size which is
a signed long.
Only buf_getwriteptr() is using k_size as unsigned.
So it safe to use it as signed.
