[pushed 00/28] Windows non-stop prep

[Pedro Alves <pedro@palves.net>]

I've now merged all the patches from the Windows non-stop v2 series,
from here:

  https://inbox.sourceware.org/gdb-patches/20250519132308.3553663-1-pedro@palves.net/

... up to patch 34.  Those which hadn't been merged yet, that is.

They had all been approved last year by Tromey.  Thank you very much,
Tromey!

Many of the patches here didn't apply cleanly on current master, due
to pervasive thread pointer <=> reference changes that had gone in
meanwhile, and also due to code in windows-nat.c having moved to other
files for the Aarch64 port.  But other than that, the patches are
largely the same.

I'll handle the rest of the series, including the actual non-stop
bits, soon.
