This is for those of you interested in tame, and skilled enough to
play along.

This is a set of almost 100 diffs to programs in the tree to use tame.
These have been done by myself, doug, florian, semarie, and a few
other people I forget.  I would make a rough guess these changes took
about 100 hours of developer time; so making programs use tame() is
pretty efficient.

None of these examples uses the path whitelist yet.

It is not perfect or final, but it shows the strategy for applying
them to the base.  It can make it through a 'make build'.  Feel free
to do tests, look for mistakes, or write diffs for other programs.

Be careful writing such diffs; you need to fully understand the
program and handle all cases.  Not all programs can be tamed, some
behaviours (like execve) are not compatible with features tame
can do.
