Done in v4.

I don't know. It was there when I picked up this patch but I can't come
up with a case in which one would want to change it. Removed in v4.

True. Removed in v4.

It does work; I've used it since before I submitted this patch. The
`--var` option is listed on `rspamd --help`. Unfortunately, Rspamd
tracks their issues on Github and I'd prefer not registering an account
there.

That was also there when I picked up this patch. I assume it is added to
the profile so that the `rspamadm` and `rspamc` programs are available
and compatible with the daemon. I don't have strong feelings about this
in either direction.

It provides 'networking for the http test. Apparently the test wasn't
working yet anyway (I had no experience in Guix tests when I sent my
versions of the patch and just assumed that they were working in Thomas'
version). The tests are now fixed in v4.
