Changes since 1.5: +3 -5 lines

Merge pkg_install-20090201 from pkg_install-renovation branch.

- DB support is always included from libnbcompat if needed
- pkg_view and linkfarm are not installed any more; they are not moved
into the attic yet, so they can easily be installed as separte package
- common configuration file to customise the behavior of various
components; this supersedes the old audit-packages.conf
- support for PKSC7 signatures (using X509 certs) and GPG signatures for
packages in a secure way. See pkg_admin(8) for how to create them and
pkg_install.conf(5) for the options to use them
- audit-packages and download-vulnerability-list are wrapper scripts
  around pkg_admin. They try to mimic the classic options if used sanely.
  "pkg_admin audit" is now an order of magnitude faster than before
- pkg_add uses libarchive and libfetch instead of external ftp and tar:
  - progress bar is currently missing for downloads
  - "pkg_add -" is no longer supported
  - no adhoc check for conficts between dependencies and already
    installed packages
  - "pkg_add -s" has been replaced with an option in pkg_install.conf,
    verification of plain detached GPG signatures is no longer supported
  - optional check for vulnerabilities before adding a package
  - if /var and /usr/pkg are on different fileystems it is twice as fast
    now
  - conflicts due to overlapping plists are checked before installation
  - pkg_add no longer plays with the process limits
- pkg_add and pkg_delete have a new destdir option; scripts have to
  either be modified to use PKG_DESTDIR or should be disabled
- pkg_add -u for now can't be used to update to the exact same version
- internal "rm -rf" and "mkdir_p" code
- all memory allocation failures are not explicitly fatal
- if a file is not removed due to a failed checksum, still remove the
  entry from pkgdb
