Add the concept of purging a package, such as with dpkg.

Browse source 
By default a package when is removed, its configuration files
and metadata files won't be removed unless the package is purged.

While here add two targets for xbps-bin:

 * purge [<pkgname>|<all>], passing the "all" string (case insensitive)
   will purge all packages that are in this state (XBPS_PKG_STATE_CONFIG_FILES).

 * reconfigure [<pkgname>|<all>], reconfigures a package or "all"
   if package hasn't been configured. Passing -f reconfigures it again
   even if it's state is ok.
