[horde] PHP 8.0 status with Horde?

[impuser at bitrealm.com]

I note that Fedora 35 was released today and that it ships with
php 8.0.  I messed around a little in horde trying to get it to
work, but it seems like there are quite a few places where some
old stuff is in place and php 8.0 killed it.  The "each" statement
is in quite a few places and it has been deprecated.

The only info I could find was on the Horde twitter saying that
it isn't compatible and once I got "test.php" to run, it said that
it wasn't fully tested.
