a/aaa_elflibs-15.0-x86_64-9.txz: Rebuilt.
Upgraded: libbz2.so.1.0.8, libexpat.so.1.6.9, libglib-2.0.so.0.6000.5,
libgmodule-2.0.so.0.6000.5, libgobject-2.0.so.0.6000.5,
libgthread-2.0.so.0.6000.5, libidn2.so.0.3.6.
Removed: libicudata.so.63.1, libicui18n.so.63.1, libicuio.so.63.1,
libicutest.so.63.1, libicutu.so.63.1, libicuuc.so.63.1.
Added: libpcre2-8.so.0.8.0, libpsl.so.5.3.2. These are needed by wget which
is used by slackpkg, so they should be in here. Thanks to OutSiderBR.
ap/lxc-2.0.11_fad08f383-x86_64-1.txz: Upgraded.
Updated from 2.0 git branch.
Ported init script updates from sysvinit-scripts.
