Python 2.7 (and Tauthon) removal preview, tentatively for June 23. Lots of KDE gone...

P475 updated against r566185 and fixed the mistake there of removing definitions in Mk/ too early. INDEX builds again, now indeed taking a lot of webengine consumers with it.

• Mark ports recursively depending on Python 2.7 for expiration on June 23.
• Fix issues addressed by sunpoet in D28665
• Mark more ports using (py-)qt5-webengine as deprecated, list from https://invent.kde.org/-/snippets/1520
• Restore some default options using py27, otherwise we'd cheat on the end user.
• Update deprecations for audio/faust

I just updated audio/faust in r565456. You can remove it and depending ports from the list.

Some ports here depend on lang/ldc which needs llvm70 (requiring python 2.7). However, there are newer versions (v1.24.0) of lang/ldc available. This newer version supports LLVM 6.0 - 11.0. @acm: are you planning on updating lang/ldc?

When the dependency will be removed?
I maintain www/yarn-node* and the slave ports yarn-node1[02] depends on the related version of node, but I don't see them deprecated. Is there another patch I'm missing?

math/py-pynleq2's dependency on flang is removed, please remove it from this list.

Exclude math/py-pynleq2 which is now py27-free

Note that this review excludes ports that depend on Python 2.7 and have already expired (on 2020-12-31) according to https://www.freshports.org/ports-expired.php

Note that the date (June 23) is not set in stone, it is a date that looked reasonable to both @swills and myself.

portmgr : this looks good and trivial, Can we have this approved soon?

Should be fine AFAICT.

See also https://reviews.freebsd.org/P475

General question: how are we going to avoid people adding 2.7 support to a port because upstream still supports it?

• bsd.port.mk: Drop support for FreeBSD 12.1
• Cleanup 1201
• Cleanup 12\\.1
• Fix over-enthousiastic cleanup in emulators/rpcs3

Rebase on r563222

This should be an update of D28406

This looks fine to me, perhaps double-check with @antoine who monitors the various builds.
