backport tracker: https://tracker.ceph.com/issues/62970


backport of #53546
parent tracker: https://tracker.ceph.com/issues/61845

this backport was staged using ceph-backport.sh version 16.0.0.6848
find the latest version at https://github.com/ceph/ceph/blob/main/src/script/ceph-backport.sh

Rely on the packaging system to provide a suitable g++ of version 11
or greater, and removing the corresponding hard-coding from
debian/rules, since cmake will then find a suitable version. This
seems better than trying to hard-code a particular version in
debian/rules, and Debian package building tools like e.g. sbuild will
then do the right thing.

This enables Reef (v18.2.0) to build on Debian bookworm in a clean
chroot.

These were previously missing. The requirement for interpreters is in
Debian policy section 10.4:
https://www.debian.org/doc/debian-policy/ch-files.html#s-scripts

Debian's packaging already adds the #! to these two postinsts. In
practice, a text executible without a #! line will likely be executed
by the calling shell, so a lot of the time we'd get away with it
unless the administrator is using an incompatible shell like tcsh.

This behaviour of shells is documented in POSIX section 1(e)(i)(b)

(cherry picked from commit eaaf807)
Unless there's a version requirement (which there isn't here),
packages should not declare a Build-Depends: or Depends: relationship
on essential packages. Policy link:

(cherry picked from commit 7ec0f69)
Update the header paragraph to link to the canonical URL for the
format, and point to dev@ceph.io as the Contact.

Also add License: stanzas to reflect the licences in use (and refer to
fuller versions in /usr/share/common-licenses/ as appropriate).

This means that packages containing this copyright file are better in
compliance with the licences concerned.

(cherry picked from commit 842d6ae)
Bring the dh compat level to 12, the most recent supported by the
oldest supported Ubuntu LTS release, 20.04. This necessitates changes
to how initscripts & systemd packaging are done.

This means that debian/control matches changelog entries, and that the
Maintainer address is up to date.

(cherry picked from commit 74188c2)
debian/ceph-base.docs only referred to a README that doesn't exist, so
remove it. Because dpkg-source doesn't reflect deletions from debian/
cf the orig.tar.gz, also remove the file in dh_auto_clean.

Then do away with the removal of the empty override of dh_installdocs;
the main benefit of which here is that debian/copyright gets installed
in all of the built packages, which otherwise lack a copyright
file.

(cherry picked from commit 96edd84)
cephadm is a compressed zipapp, and dh3_python3 doesn't understand
this sort of binary file, so fails to produce the required python3
dependency. So specify this explicitly in debian/control

(cherry picked from commit efd469e)
Installation of init scripts properly belongs with dh_installinit, so
move the installation there.

That means we no longer need the override of dh_auto_build, which
simplifies the rules file.

(cherry picked from commit 67abe9c)
In the cases of ceph-base, ceph-common, and ceph-fuse, this picks up
that these packages contain python scripts and adds a necessary
python3 dependency. In the case of ceph-volume it additionally parses
the requirements.txt file.
