[arch-dev-public] RFC: (devtools) Changing default compression method to zstd

Hello again,

We are on our way to getting zstd merged.

The planned merge window for this is **2019/12/27** at around 20:00 Europe/Berlin time.
Several team members will be meeting at the 36c3, so we figured this is a good opportunity to do this,
as it makes sure that several people are aware, ready, and together for this - should anything immediately explode.

This has been ACK'd by anthraxx. Foxboron is also aware.
I have been mentioning this on IRC, and discussed it with anthraxx via e-mail.
This mail serves to formalize the plans.

**There is one hard requirement on the merge happening:**

All critical Arch Linux production infrastructure needs to be ready.
The known-unsolved problems are labelled below, please see to them if any of you can.
I will also take a look myself, but I do not have much involvement with these parts of the puzzle,
so I would really appreciate someone with more in-depth knowledge taking a look.

If the known issues are solved and nothing major comes up, the deployment will happen as planned.

Unsolved: This needs fixing. I would *really* like someone from devtools to take a look at this, but if unsolved i will also attempt to fix it.

Unsolved: This needs fixing. If nobody else gets to it, I'll see to it myself.

Solved: This is indeed irrelevant (see Eli's reply)

Solved: This is indeed a dead project (see Eli's reply)

Solved: arojas said this will be fixed after zstd is deployed. This is also non-critical.

> - devtools:
Solved: Patches ready, will be merged with the switcharoo.

I encourage every Arch Linux project maintainer to check their own code for hardcoded xz extensions, you probably know your code best.
