Cy Schubert f27f47054d As per the developers handbook (5.3.1 step 1), prepare the vendor trees for
import of new ipfilter vendor sources by flattening them.

To keep the tags consistent with dist, the tags are also flattened.

** Revised (for MD5): RLR 4/27/91 **
** -- G modified to have y&~z instead of y&z **
** -- FF, GG, HH modified to add in last register done **
** -- Access pattern: round 2 works mod 5, round 3 works mod 3 **
** -- distinct additive constant for each step **
** -- round 4 added, working mod 7 **
