Backout libinstall.a -> libpkg commit.

Discussed with: erwin, brooks, bapt

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

- 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.

Use humanize_number to report pen-sizes so people don't have to count
the digits when trying to install openoffice.

- Backout 1.15, it was committed by accident

Pointy hat to: pav

- Restore functionality broken in previous commit; we need to be able to report
multiple installed packages with the same PKGORIGIN.

NOCRYPT -> NO_CRYPT

Join the 21st century: Cryptography is no longer an optional component
of releases. The -DNOCRYPT build option still exists for anyone who
really wants to build non-cryptographic binaries, but the "crypto"
release distribution is now part of "base", and anyone installing from a
release will get cryptographic binaries.

Approved by: re (scottl), markm
Discussed on: freebsd-current, in late April 2004

- Properly build both crypto and non-crypto versions of the
package management tools.

- Drop redundant dependency of pkg_create(1) and pkg_delete(1)
on crypto libraries now that they do not link with libfetch.

Replaced black magic with white magic.

Use some black make(1) magic to make pkg_install build even without
Makefile.inc in parent directory (e.g. when checked out from cvs as a module).

- Backout botched attempt to introduce MANSECT feature.
- MAN[1-9] -> MAN.

Set the default manual section for usr.sbin/ to 8.

$Id$ -> $FreeBSD$

Use `foo/bar.a' instead of `-Lfoo -lbar' for linking to static internal
libraries, so that `ld -f' in can create correct dependencies for
yet-to-be-built libraries.

Make this stop trying to go into /usr/local and inherit the settings
from above instead.
