sysconf(3) returns a long, not an int.

Do not change owner, group, or mode when package database directory and
its contents are created with pkg_add(1). It may happen when the packing
list contains @owner, @group, or @mode.

Spelling fixes for usr.sbin/

Backout libinstall.a -> libpkg commit.

Discussed with: erwin, brooks, bapt

- Take libinstall.a out of pkg_install and make it a proper shared library.
- Rework the wrapper support to check libpkg version as well as pkg_install
version.
- Add libfetch to _prebuild_libs.
- There are no new features introduced.

Notes: the API is not stable, so basically, do not use libpkg in your
projects for now. Also there's no manpage for libpkg yet, because the API
will change drastically. I repeat, do not use libpkg for now.

Fix pkg_add behaviour to preserve pathnames.

When using @cwd %%FOO%%, we must ensure to return in the original
prefix later, but doing so with @cwd %%OLDPREFIX%% (having
PLIST_SUB+="OLDPREFIX=${PREFIX}") hardcodes the value in the packing
list. That's not really a problem when dealing with ports but that's
a problem with packages since pkg_add -p option only overrides the
first @cwd occurrence.

This patch allow us to use @cwd without any argument. If no
directory argument is given, it will set current working directory
to the first prefix given by the @cwd command.

Downgrade WARNS level to more tolerable value. Attempt to fix
casts as lvalue usage whenever possible.

- 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

Pkg_add refused to process package whose packing list contains @exec/@unexec
before any file names. This change makes pkg_add to process those
packages if @exec/@unexec commands don't contain any %[fFB]. Also
enable @exec/@unexec that have %D if the installation prefix is known to
pkg_add.

Use err(3). Cosmetics in usage string and man page.

Change the naming conventions for preserve'd files and also document
the option in pkg_create. Now preserved files start with a . and are
named .<filename>.<pkgname>.backup so that their purpose is more clear.

Note that just using the preserve option without proper pkg_deps
is also foolish since packages being deleted in the incorrect order with
preserve on can generate some odd results.

Whoops, only attempt to back up the file if it exists. :-}

Add support for @option preserve - moves existing files out of the way
before replacing them (using pkgname to make this hopefully unique).
Delete also moves them back, if they exist, resulting in a package
which can be "backed out" with reasonable safety.

Make sure permissions on registry location are readable by pkg_info.
Add new % sequence expansion for command execution.

Added option for current directory prefix in @exec (without which it's pretty
useless).

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

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.
