Spelling fixes for usr.sbin/

- Add support for xz compression to pkg_create, bzip2 remains the default
compression algorithm.
- Bump PKG_INSTALL_VERSION to 20101012.

Add a -n option to pkg_create(1), to inhibit duplicate work.

When run without this option, multiple runs of `pkg_create -Rb' will
recreate common packages multiple times. This can take a lot of time
for large packages. With the -n option `pkg_create -b' checks with
stat(2) and skips packages that already exist.

Note that this may *not* be safe of the existing output file is not
really a package, or if it has been corrupted, modified or otherwise
tinkered with between subsequent pkg_create runs. For this and POLA
reasons, the default behavior is to *rebuild* the packages, and the -n
option can be used when we know it is `safe' to run in no-regenerate
mode.

Add -R modifier for the mode when pkg_create(8) creates package file
from the locally installed package. When this modifier is specified
pkg_create(8) will also create package files for all packages on
which that locally installed package depends.

- pkg_add spawns itself as argv[0] when installing dependent packages, to
enable the use as a port on older systems

- use absolute paths in all calls to external programs, to account for strange
PATH settings

- use INDEX or INDEX-5 depending on FreeBSD version, to enable the use on
FreeBSD 4.x as a port.

- conditionalize all 4.x/5.x differences on __FreeBSD_version, so that the
pkg_install tools can be kept in sync on 4.x and 5.x

- Bump PKG_INSTALL_VERSION

* Add explicit conflict-checking to the package tools. Packages can
register a list of other packages with which they conflict (via the
-C option to pkg_create), and they will refuse to install (unless -f is
specified) if one of the listed packages is already present.

* Update documentation for the new feature as well as fleshing out some
existing documentation.

* Bump PKG_INSTALL_VERSION so this feature can be tested for.

Improve the Bzip2 handling.

WARNS=2 cleanup.

(forced)

Forgot to mention: creation of a full-fleged package archive requires some
changes in bsd.ports.mk, because currently it doesn't install some files
that are usually packed into the package archive (+MTREE_DIRS, +DISPLAY
and so on). Support for this will be committed later.

- Allow package archive to be created from a locally installed package. This
allows for an easy way to backup old version of port prior to installing
a new one;
- silence compiler warnings by killing some unused variables and adding
all includes necessary.

- Add ability to handle bzip2-compressed packages;
- fix cosmetics to shut-up compiler in -pedantic mode (axe several unused vars
and provide default clause in several switch() statements).

No response from: -ports

Add "-o" option to pkg_create(1) and pkg_info(1). This option intended to record
a path of the port from which package has been created within FreeBSD Ports
Collection and will be used to improve pkg_version(1) and similar tools.

Revert $FreeBSD$ to $Id$

Make the long-awaited change from $Id$ to $FreeBSD$

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.

Bring forward my changes from 2.1

1. Add proper dependencies to the library in my Makefiles. This was pointed
out by Bruce.
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.

Add true support for dependency lists.

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.

Add `-h' option to force tar to follow symbolic links

Added and doc'd -X flag to pkg_create that allows you to specify an exclude
list for the final package.

Made staging area configurable rather than assuming /tmp (-t)

Lots of misc tweaks, support for arbitrary separators in pkg_info, more
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).

This commit was generated by cvs2svn to compensate for changes in r327,
which included commits to RCS files with non-trunk default branches.

The release version of my package install suite. Please see man pages
