Migration of libuv1 to salsa

[Dominique Dumont]

Hello

libuv1 is used by projects than nodejs, Perl6 cmake and other. It's still 
hosted on alioth in in javascript team repo. It's only uploader is Luca Bruno. 
All uploads since 2016 were done by team uploads.

Since Alioth is now deprecated, it's time to migrate libvu1 to Salsa.

After discussion with Jérémy, we think that libuv1 should be hosted in Debian 
group on Salsa.

Luca, as official uploader of libuv1, do you mind if I take over libuv1 ?

The plan is to:
- migrate libuv1 repo in Debian group on Salsa
- dust-up the package if needed
- release 1.20 on experimental

You're all welcome to join the effort. Please tell me if you want to be added 
(or kept) as uploaders.

All the best

Dod
