plain 0 should be used. This happens to work because we #define
NULL to 0, but is stylistically wrong and can cause problems
for people trying to port bits of code to other environments.

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
later at pkg_delete time to verify that you're deleting what you added.
This, of course, does NOT cover the case where a file you still need
hasn't changed! That's a tougher problem to solve, and this provides
only the minimal amount of safety belt. MD5 checksums are stored in comment
fields, so packages produced with these tools are backwards compatible with
the older ones.
1. pkg_create now has a -P argument for specifying dependencies on the
command line.
2. pkg_add will honor dependencies and chain-load them automatically if
it finds the required package(s) in the same directory as the package
that is being loaded. For best results, install packages from a directory
containing all the packages you'll possibly need
(like /usr/ports/packages/all).
2 remaining flaws:
1. pkg_add looks in one place (where you were when you loaded the primary
pkg) for depended packages. If you can come up with a search path scheme
that's not a total hack - be my guest!
2. Recursive dependency expansion can result in the name of a dep being
listed more than once. This doesn't bother pkg_add since it checks
for package existance with pkg_info and will skip already-loaded packages.
I don't know how/if pkg_delete handles this yet, however. I need to look
into it.
Made pkg_add -n less bitchy.
Made -p in pkg_add override "default" package location in pkg_create.
Added concept of "slave" and "master" modes, allowing many different things
to be done to packing lists on the fly. This is really something for
front-end drivers to use, but also something for the more expert user.
rename()'ing files before trying to copy them, thus saving
considerable time when targets and staging area are on same filesystem.
