'RELENG_2_1_6_RELEASE'.

This commit was manufactured to restore the state of the 2.1.6-RELEASE image.
Releases prior to 5.3-RELEASE are omitting the secure/ and crypto/ subdirs.

2. Add a "feature" to pkg_create (OK, OK, it's a miserable hack!) to get
   it to dump its internal packing list out so that the `fake-pkg' rule in
   bsd.port.mk can generate a more meaningful packing list.

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.

lines.  Done.
