[Libosinfo] [osinfo-db-tools PATCH v2 00/16] Add support to meson build system

[Fabiano Fidêncio]

The following patch series:
- Add suppor to meson build system;
- Drop support to autotools build system;

If we decide to go for it, there's still work to be done in
libvirt-jenkins-ci as it has to have meson support added there.

Changes since v1:
https://www.redhat.com/archives/libosinfo/2019-June/msg00063.html
- Improve commit message in the patch dropping config.h
- Some cleanups on cfg.mk were done;
  - In order to do so, a patch indentng includes/defines in util.h
    was needed;
- Updated maint.mk in order to avoid doing de s/$(SED)/sed hack;
- Added the .spec files to the generated tarball;
- Don't purge the git checkout, just delete the build dir when
  running `./prepare-release`;
- Moved GNUmakefile, cfg.mk, and maint.mk to build-aux dir;
- Introduced a new patch dropping the non-valid configure options,
  as it makes clear that we're not removing them just because we
  are switching to meson;

A few points that still have to be considered:
- meson version in the major distros:
  - Fedora 29 - 0.50.0
  - Fedora 30 - 0.50.1
  - Debian 9 - 0.37.1
  - Debian 10 - 0.49.2
  - OpenSUSE 15.1 - 0.51.0
  - Ubuntu 18.04 - 0.45.1-2
  - Ubuntu 18.10 - 0.47.2
  - Ubuntu 19.04 - 0.49.0
  - FreeBSD - 0.51.0
    - This is what internet returns me as part of devel/meson
  - CentOS 7 - not present
    - EPEL: 0.47.2
  If we do the switch, we'd stop building on:
  - Debian 9 & older;
  - Ubuntu 18.10 & older;
  - EL 7 & older;

  For osinfo-db-tools, I truly believe it's not a big deal, as it'd
  be for more important packages (as libvirt).

- meson support on libvirt-jenkins-ci:
  - I'll happily work on that before having these patches merged!

- a last release with autotools:
  - I'd like to have a last release with autotools, including some
    patches that are still pending review (as the ones using libsoup
    instead of gvfs);

- can we have a more generic/simplified version of GNUmakefile &
  friends?
  - That would take me some considerable amount of time to do and,
    although I'm not discarding this for the future, it's not something
    I'd like to consider for now.
