use bn_asm_vax.S (from netbsd); test + ok by miod

use asm code for i386, except for the CBC code, because
it is not clean PIC code.
add <machime/asm.h> support to x86unix.pl
tested by: nick (on 30386), henning, djm, tedu, jmc and more;
no shlib minor crank necessary, only internal symbols changed.
