mod_http2/mod_md upkeep

=46rom 2.4.x STATUS: "I guess Stefan will take care."

FYI: Stefan is totally under water and has been for months now, curl =
being the first project to be hit by the LLM craziness.

I have in the past silently synched changes between the repositories for =
people who drop things into trunk and never proposing backports or =
compatibility with 2.4.x. That service I can no longer do. If you change =
anything in mod_http2 or mod_md, it's now your task to do this.

For me "trunk" is a graveyard and an obstacle, a necessary evil for =
maintaining 2.4.x. This might sound harsh to some, but the last decade =
has only confirmed this as a reality (I expressed this in the past). I =
can only regard the recent uptick in trunk changes as going in a =
direction I am no longer able (as in having the mental strength and =
time) to follow.=20

If there is something puzzling in the modules' code, please contact me =
and I am happy to help. But I have to step back from the daily security =
list madness and the tidy up work. At some point, it will probably be =
best to set the github modules repository to archive mode.

Cheers,
Stefan
