PR 241526: redis-related infrastructure update

[osa]

Summary

Redis 5.x is stable and mature enough, so it's time to update database/redis port. However, let's keep existing redis 4.x in a separate port, databases/redis4 for the following reasons: backward compatibility at first and for stability as second (redis 4.x will be supported until redis 6.0 will be released).

Could you use devel/arcanist, or at least generate a diff with full context like it does, with svn diff -x -U9999 or git diff -U9999.

[mfechner]

I checked the www/gitlab-ce port and it seems to work fine the new redis version. You only had to adapt your patch, as the port has already version 12.4.2.

Thanks for the comment, Mathieu. I've just tried to update the revision and arcanist has failed with Exception Bad origin state 7.
The svn diff -x -U9999 command creates a huge patch, so I don't think I can post it here, so I'm ready to use -U5 in this case.
