Subject: [gentoo-alt] [PREFIX] Prefix rsync now includes full gentoo-x86 repo

All,

This is a headsup mostly for developers.  The (good) news for users is
that all packages from regular Gentoo are now also available for Prefix
albeit being masked by missing keywords.

Because of a growing whitelist.txt, and the tiresome process of adding
to whitelist.txt what is necessary, then waiting around an hour to sync
and find the next missing package, I decided to include all packages
from gx86 in the Prefix rsync tree.

Of course "each advantage has its disadvantage", to quote Cruyff.  In
the attached figure, the most prominent disadvantage is made visual:
generation time has increased from ~12 to ~17 minutes.  For the 30
minutes rotation this obviously makes no difference.

Notice the bump of time necessary by egencache around 20:00, that is the
time Zac committed "cache-formats = md5-dict pms" to
metadata/layout.conf.  In the Prefix tree, there now is a
metadata/md5-cache directory that should ultimately fix the bug we
observed in the past [1], but gentoo-x86 people have been affected by
now too [2].  That sort of is a  proof that I was correctly not
convinced in comment #17 of said Prefix bug [1].

In the near future, we (Prefix) might jump ahead and stop distributing
the old metadata/cache, but for now we have both, like gx86.

Because the Prefix overlay now "overshadows" the gx86 tree, I've removed
whitelist.txt, since it's obviously no longer used.  Nothing is
necessary any more to "include" something in Prefix, as everything there
is, should be there now.
