Backout libinstall.a -> libpkg commit.

2011-05-17T19:11:47+00:00

Discussed with:	erwin, brooks, bapt

- Take libinstall.a out of pkg_install and make it a proper shared library.

2010-04-23T11:07:43+00:00

- 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.

Various fixes.

Optimize package registration/deregistration. Previously, when looking up the

package name for the origin of a dependency, all entries in /var/db/pkg were
traversed for each dependency of added/removed package.  Now, gather all the
origins first, then do the lookup in a single pass over /var/db/pkg.

This should provide a major speedup for packages with hundreds of dependencies.
