[MIR] pkgconf, replacement for pkg-config

Adding a bug task for pkg-config and rls-ll-incoming tag, to bring the package ownership question up for discussion with the Foundations team.

Foundations agreed to take care of pkgconf (as of #ubuntu-meeting 2022-12-08). So I'll subscribe ~foundations-bugs and we can move on with this MIR.

"vorlon> pkg-config will be a removal as soon as pkgconf is clear"

update-notifier fails to build in lunar-proposed now, the error has been reported upstream as a regression in august with no reaction since, https://github.com/pkgconf/pkgconf/issues/260
are we convinced it's a better alternative?

I opened an rc bug in Debian for this issue: #1026216
and reverted that patch in Ubuntu.

Review for Package: pkgconf

[Summary]
MIR team ACK under the constraint to resolve the below listed
required TODOs and as much as possible having a look at the
recommended TODOs.
This does not need a security review
List of specific binary packages to be promoted to main: pkgconf, libpkgconf3, pkgconf-bin, libpkgconf-dev, pkg-config

Notes:

Please address/clarify the following :

Required TODOs:
1. Does it run autopkgtests ? There is a test suite in the sources which runs at build time,
   that could be also run as autopkg, but I do not see anything under
   https://autopkgtest.ubuntu.com/packages/pkgconf or pkgconf in
   https://autopkgtest.ubuntu.com/testlist#index-p

Recommended TODOs:
2. Debian has bumped version to 1.8.1. There is a very recent cve, CVE-2023-24056 :
   https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2023-24056
   This cve is addressed upstream
   (https://github.com/pkgconf/pkgconf/commit/628b2b2bafa5d3a2017193ddf375093e70666059)
   and pull into debian in 1.8.1
   (https://salsa.debian.org/debian/pkgconf/-/commit/05e3a9175a07194da5d7b80b9aa1f2f639d37db0).
   It would be nice to either sync from debian or at least backport the cve fix.

3. The source package produces 5 binaries one of them being pkg-config, which iiuc is transitional
   package, can you please clarify if we need it in main too ?

- The package should get a team bug subscriber before being promoted

[Duplication]
pkgconf is a replacment for pkg-config, since debian moved to it.

[Dependencies]
OK
- no other Dependencies to MIR due to this
  - pkgconf checked with `check-mir`
  - all dependencies can be found in `seeded-in-ubuntu` (already in main)
  - none of the (potentially auto-generated) dependencies (Depends
    and Recommends) that are present after build are not in main
- no -dev/-debug/-doc packages that need exclusion
- No dependencies in main that are only superficially tested requiring
  more tests now.

Problems: None

[Embedded sources and static linking]
OK:
- no embedded source present
- no static linking
- does not have unexpected Built-Using entries
- not a go package, no extra constraints to consider in that regard
- Does not include vendored code

Problems: None

[Security]
OK:
- history of CVEs does not look concerning
- does not run a daemon as root
- does not use webkit1,2
- does not use lib*v8 directly
- does not parse data formats (files [images, video, audio,
  xml, json, asn.1], network packets, structures, ...) from
  an untrusted source.
- does not open a port/socket
- does not process arbitrary web content
- does not use centralized online accounts
- does not integrate arbitrary javascript into the desktop
- does not deal with system authentication (eg, pam), etc)
- does not deal with security attestation (secure boot, tpm, signatures)
- does not deal with cryptography (en-/decryption, certificates, signing, ...)

Problems: None

[Common blockers]
OK:
- does not FTBFS currently
- does have a test suite that runs at build time
  - test suite fails will fail the build upon error.
- This does not need special HW for build or test
- no new python2 dependency

Problems:
- does it have a test suite that runs as autopkgte...

Required TODOs:

Done.

Recommended TODOs:
2. Debian has bumped version to 1.8.1. There is a very recent cve, CVE-2023-24056 :

Syncd.

$ reverse-depends -r lunar -b pkgconf |wc -l
83
$ reverse-depends -r lunar -b pkg-config |wc -l

$ reverse-depends -r lunar -b pkg-config -c main |wc -l
606
$ reverse-depends -r lunar -b pkgconf -c main |wc -l

Unless we want to patch +600 main packages to switch to pkgconf instead of pkg-config I prefer to keep it (I don't know why pkgconf is not just providing pkg-config, probably to ensure people have smooth upgrades).

Maybe in some years from now, we can drop the transitional package and move to a Provides: one, or patch the Debian/Ubuntu archives to use the new naming.
For sure this is something that will eventually come from Debian I would say.

Thanks Gianfrnaco, this is good to proceed with MIR.

Looks like this is ready for promotion. I guess Foundations should do the seed change, in order to take ownership.
