[Dev] libretools 20180804 release announcement

[Luke Shumaker]

I just released libretools 20180804 to [libre] and pushed the source
tarball to <https://repo.parabola.nu/other/libretools/>.

TL;DR:
 - You should `rm -rf /var/cache/pacman/pkg-*/`
 - libremakepkg now disables networking during prepare()
 - Merging `/etc/libretools.conf.pacnew` isn't terribly important.
 - `chcleanup` / `libremakepkg clean-pkgs` now not only removes
   packages that it thinks shouldn't be installed, but also installs
   packages that it thinks should be installed.

Changes from 20180530 to 20180804:

 - librechroot/libremakepkg/chcleanup
   * librechroot: Remove the hack where packages for other
     architectures are cached in `/var/cache/pacman/pkg-$CARCH/`
     instead of `/var/cache/pacman/pkg/`.  This should no longer be
     nescessary with current versions of db-import.
   * chcleanup:
     . Correctly handle depends_x86_64=() arrays and
       similar. https://labs.parabola.nu/issues/1311
     . Also install packages that it thinks should be installed,
       rather than just removing packages that it thinks shouldn't.
   * libremakepkg:
     . Don't run pkgver() and modify the PKGBUILD
       https://labs.parabola.nu/issues/1919
     . Disable networking duing prepare()
       https://labs.parabola.nu/issues/1920
 - xbs: Remove.  As previously announced, the XBS family of tools has
   now been dropped.  The associated settings in
   `/etc/libretools.conf` have been removed.  Merging the .pacnew file
   isn't important; it just drops the settings.
