'RELENG_2_2_5_RELEASE'.

This commit was manufactured to restore the state of the 2.2.5-RELEASE image.
Releases prior to 5.3-RELEASE are omitting the secure/ and crypto/ subdirs.

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.

intelligent name handling in pkg_create.  Most of these files are changed
because of rcsid's being different in my cvs tree and freefall's (foo).

for info.
