xbps-0.11.0 (???):
* libxbps: improve xbps_purge_pkg() in case that the process was
unexpectedly interrupted, do not error out unless the unregister
phase return an error value.
* libxbps: when unpacking a package that replaced another package
due to virtual packages, preserve its configuration files if
they already existed.
