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.

Add missing `void' keywords.

- Add long options to pkg_install.
- Remove check for '-?' as it's not listed in authorized options.
- Bump PKG_INSTALL_VERSION to 20080530.

Cleanup of userland __P use

Allow variable amounts of verbosity.

Add -o/-O options to pkg_version:

-o Show the origin recorded on package generation instead of the
package name.

-O Only list packages whose registered origin is origin.

Add an -I option to pkg_version:

-I Use only the index file for determining if a package is out of
date. This is much faster than using the version number from a
port's Makefile, at the expense of potentially giving an incor-
rect result if the index file is out of date.

Without this option, the index file is only consulted if "make -V PKGNAME"
cannot be used.

Approved by: portmgr (krion)

Add -q to usage() and mark the "index" argument as optional.

Add a -q flag to pkg_version. It suppresses the output of <,=,>.
This makes it possible to "portupgrade `pkg_version -q -l '<'`".

- match package version numbers with relational operators

- use glob patterns when matching packages by origin

- csh-style {...} choices in glob matching

- pkg_info: new flag -E (list matching package names only)

- pkg_version: new flag -T (test if a given name matches a pattern)

- new flag -X (interpret pattern as an extended regular expression)
