libpkg is a library provided by pkg

Goal: reorganize common functionality among pkg_* tools into a single library. Provide the pkg_* tools similarly to the way fetch/libfetch exist?

Some thoughts from WesleyShields:

1. move the shared code of pkg_* into a library
2. make pkg_* use said library
3. optimize the internals of the library
4. at this point you should have a good understanding of pkg internals and what's good and bad about them
5. possibly re-write pkg_* and libpkg to remove the ugly parts or make them better
