Add initital codeowners file

[wilzbach]

Similarly to dlang/phobos#5573

Code owners are automatically requested for review when someone opens a pull request that modifies code that they own. When someone with admin permissions has enabled required reviews, they can optionally require approval from a code owner.

Moreover, it's a simple plain-text format:

A CODEOWNERS file uses a pattern that follows the same rules used in gitignore files. The pattern is followed by one or more GitHub usernames or team names using the standard @username or @org/team-name format.

For more information, the help page goes into more details.

I tried to use some insights from @MartinNowak's git blame analyzer, but this isn't perfect and your feedback and input would be very welcome: what are files in the DMD codebase that you feel comfortable with? Are there mappings that I add that don't reflect the status quo?

We had some troubles with GitHub at Phobos, but here's an example on how it will look in live.

CC @dlang/team-dmd @Geod24 @LemonBoy @kinke @redstar @rainers @mathias-lang-sociomantic @thewilsonator @luismarques @JohanEngelen and all other awesome DMD contributors

(I will wait a few days and if you don't confirm that you are ok with being pinged on a PR, I will remove you from the file for now).

Thanks for your pull request, @wilzbach!

Bugzilla references

Your PR doesn't reference any Bugzilla issue.

[thewilsonator]

Awesome.

[redstar]

Many thanks for doing this!

Fine with me. According to the file headers, you can assign src/ddmd/vcbuild/, src/ddmd/root/longdouble. and src/ddmd/backend/varstats.* to me.

BTW: s/GiHub/GitHub/ ?

As the creator of this module, I insist being notified of changes. ☺️

This is fine, I'm maintaining the c++ branch anyway.

I would suggest to also include @yebblies here, but I'll let him confirm that.

[wilzbach]

Ok I finally found time to get back to this. Anyone still missing on this file or is it good to go as an initial version? (It can always be modified later)

[JinShil]

Is @yebblies still active with dlang? I haven't seen anything from him in a while.

Same here :/
Should I remove him from this file or should we simply take this as an initial version and gradually improve it?
While some contributes will fade, hopefully new contributors will come, so I expect the CODEOWNERS file to be updated from time to time.
For example, you might want to add yourself to the file ;-)

Remove @yebblies and add him when he shows up. We should track a 3 months long moving window or so.

I think I'm still earning my wings. When I feel confident, I'll submit a PR.

Ok. Done.

Good idea, but remembering to update the CODEOWNER files every month could be tricky.
