[ratelimits] Separate RPZ and RRL patches

[Vernon Schryver]

Separate versions of the RPZ and RRL patches are now available.
The link on http://www.redbarn.org/dns/ratelimits points to a page
with the 6 separate patches as well as the 4 combined patches.

The previously announced combined RPZ+RLL patches are strongly
recommended over the separate patches.

If you use RRL but not RPZ, installing a combined RPZ+RRL patch is
unlikely to cause any problems, because you won't be exercising the
RPZ code.

If you use both RPZ and RRL, then you *must* use a combined RPZ+RRL
patch because no RRL patch for current BIND9 source is compatible
with the separate RPZ patches.  The separate RPZ and RLR patches
try to change some of the same code.

If you use RRL and later decide to try a RPZ speed up patch, you
will need to start over patching your BIND source with a combined
RPZ+RRL patch.
