Hello Guix!

I=E2=80=99ve pushed a =E2=80=98wip-guile3.0-packages=E2=80=99 branch, which=
 renames =E2=80=9Cguile-next=E2=80=9D
to =E2=80=9Cguile=E2=80=9D, renames =E2=80=9Cguile3.0-=E2=80=9D packages to=
 just =E2=80=9Cguile-=E2=80=9D, and changes a
few more occurrences of =E2=80=98guile-2.2=E2=80=99 to =E2=80=98guile-3.0=
=E2=80=99 in package inputs.
It should start building here:

  https://ci.guix.gnu.org/jobset/wip-guile3.0-packages

We=E2=80=99re talking about the subset of packages known to support Guile 3=
.0,
which includes all the dependencies (and dependents, hopefully) of Guix,
plus a bunch of other packages.

Initially I thought about applying the patch to =E2=80=98master=E2=80=99.  =
However, it=E2=80=99s
not that simple: we=E2=80=99d also need to have all the modules for Shepherd
compiled for Guile 3.0, same for mcron, and same everywhere we use
=E2=80=98with-extensions=E2=80=99 (for =E2=80=98guix pack=E2=80=99, (gnu sy=
stem vm), etc.).

Thus, I=E2=80=99m inclined to do the big switch in =E2=80=98core-updates=E2=
=80=99, where we
could directly change =E2=80=98default-guile=E2=80=99, and thus everything =
would switch
to Guile 3.0 at once.  (In the meantime, the branch above allows us to
test the packaging bits.)

Thoughts?

Thing is, it=E2=80=99d be great to have Guile 3.0.1, which could happen any=
time
now but just needs synchronization.
