- Belatedly update Entangle to version 1.0 (newer versions are available,
but they cannot be easily ported without making changes to the code as
they crash with segmentation fault unmodified)
- Now builds itself using Meson instead of GNU autotools and make, hence
drop no longer relevant knobs from the Makefile
- Adjust dependencies: remove unused ones, limit the scope of `gettext'
to NLS case only, drop version specification from `USES=python' which
is not needed since r564032 and was probably not very accurate anyway
- Reclaim maintainership after previous maintainer had stepped down, and
chase HTTP 302 redirection in the MASTER_SITES and WWW line while here
