Hmm. I really would prefer smaller patches.
- Add meson;
- Drop autotools;
- Change spec files;
- ...

I didn't go through the patch, will do that in the next days ... but a
few things should be considered here:
- meson >= 0.49.0 basically means the project won't be built on Debian
< 10, Ubuntu < 19.04 ... which may be a problem for the project, if
you're following libvirt supported distros;
- please, take a look at the work done on libvirt-jenkins-ci and try
to adapt this one to follow the targets we have there;
  - It'll force the addition of a `ninja syntax-check`, instead of
having the syntax-check as part of the tests;

Again, I'll carefully go through this patch in the next days.
