It might be necessary to further raise the multiplier if
this one (2) is insufficient.

Fix FTBFS against system asio by using bundled version instead (Closes: #914112)

See merge request mariadb-team/galera-3!2

Previously the Salsa-CI system required priviledged runners to run
piuparts and reprotest. Not anymore, so these can be removed.

Update to upstream version '25.3.24'
with Debian dir c1786ef99b6536ede8ce829cf21318f18a3d38d3

This reverts commit 1460cfa1.

After discussion on the reproducible-builds@lists.alioth.debian.org
it was decided this fix is wrong, as it most likely makes the debug
symbols unusable, and fixed a non-issue as the same old revision
(before this change, that was never uploaded) started to work on
reproducible-builds.org testing infra. So the root cause of the
failure apparently was something in the r-b.o infra, not this Galera.

modernize debugging symbols

This shifts from the manually-generated -dbg package to the
automatically-generated -dbgsym packages.  See
https://wiki.debian.org/DebugPackage for more details.
