Merge branch 'master' into staging-next
There ver very many conflicts, basically all due to
name -> pname+version.  Fortunately, almost everything was auto-resolved
by kdiff3, and for now I just fixed up a couple evaluation problems,
as verified by the tarball job.  There might be some fallback to these
conflicts, but I believe it should be minimal.

# Usually, sympow has 3 levels of caching: statically distributed in /usr/,
# shared in /var and per-user in ~/.sympow. The shared cache assumes trust in
# other users and a shared /var is not compatible with nix's approach, so we
# set VARPREFIX to the read-only $out. This effectively disables shared
# caching. See https://trac.sagemath.org/ticket/3360#comment:36 and sympow's
# README for more details on caching.
# sympow will complain at runtime about the lack of write-permissions on the
# shared cache. We pass the `-quiet` flag by default to disable this.
