metalog -> makefs is broken again in -HEAD

[Adrian Chadd]

hi,

ok, so here's the hilarity.

We don't really have tools for consistently manipulating
metalog/manifest files. So, in order to do things like
add/delete/modify things in the manifest file, we need to do some ..
hackery.

So that's what filter.pl does. It takes in the metalog file and does a
replace or append. It currently doesn't have a "delete" method.

the .tmp file is "the extra files that we add /after/ the system
installs". Ie, it's the customisations done. It goes through filter.pl
and then the resultant metalog file has the complete thing that's
going into the image.

When I get around to adding package support for mips (not mips_ap)
then it'll also have a second intermediary metalog file that has the
combination of all of the package installs, so makefs knows what to
do.

Ok, so for metalog versus manifest. I remember doing it one way and
then brooks saying "Don't do that, here's the bugs". I'll have to go
over that and see.

Thanks,
