Support more modern Lua versions - to keep only one in main

[Christian Ehrhardt ]

Hi,
in the past we have tried to move 5.1->5.2 (bug 1324062) but right now we have:
For older Lua versions being held in main I found:
- apache2-bin depends on lua5.2
- dovecot depends depends on lua5.3
And a request for lua5.4 in bug 1909665.

Step I:

I'd request to check if we can:
- at least move apache2 to lua5.3 to be able to demote lua5.2 in Hirsute
- [1] suggests that 5.3 might work right away

Step II:

Further down the road I'd request to check and work on moving dovecot+apache2 to lua5.4 (unless it turns out impossible). Then we could completely move to 5.4 and demote 5.3 as well.
And we could make ibus-libpinyin a sync again then (see bug 1909665).

I verified that apache2 builds fine against lua5.3 and filed [1] in Debian. This is similar to [2] and the apache2 maintainers promptly bumped the build-dep back then.

(I also verified that apache2 does *not* build against lua5.4)

I've posted an MP with a merge of the Apache2 with the lua5.2->5.3 change.

[Launchpad Janitor (janitor)]

This bug was fixed in the package apache2 - 2.4.46-4ubuntu1

---------------
apache2 (2.4.46-4ubuntu1) hirsute; urgency=medium

  * Merge with Debian unstable, to allow moving from lua5.2 to
    lua5.3 (LP: #1910372). Remaining changes:
    - debian/{control, apache2.install, apache2-utils.ufw.profile,
      apache2.dirs}: Add ufw profiles.
    - debian/apache2.py, debian/apache2-bin.install: Add apport hook.
    - d/index.html, d/icons/ubuntu-logo.png, d/apache2.postrm: replace
      Debian with Ubuntu on default page.
      + d/source/include-binaries: add Ubuntu icon file
    - d/t/control, d/t/check-http2: add basic test for http2 support
    - d/p/t/apache/expr_string.t: Avoid test suite failure due to timing
      issue reading error log too quickly after request, by adding a sleep.
      (LP #1890302)
    - d/apache2ctl: Also use systemd for graceful if it is in use.
      This extends an earlier fix for the start command to behave
      similarly for restart / graceful. Fixes service failures on
      unattended upgrade.
  * Drop:
    - d/perl-framework/t/modules/allowmethods.t: disable reset test. This
      was re-added by mistake in 2.4.41-1 (Closes #921024)
      [Included in Debian 2.4.46-3]
  * d/apache2ctl: Also use /run/systemd to check for systemd usage
    (LP: #1918209)

For the aforementioned lua removal I've filed:

[Paride Legovini (paride)]

I think "Step I" of this bug has been reached: we have only lua5.3 in main.

Eventually we'll get to "Step II" and move to lua5.4, which is supported by apache2 >=2.4.47 [1], but there's no MIR for lua5.4 at the moment (LP: #1909665 lua5.4 MIR is a Wontfix), so no action is required at the moment.
