Fails builds on warnings and warn on possibly uninitialized variables

@adrien.plazas please look at the third patch. At least one of them looks like a real omission which I've so far just pampered over.

The capitalization on the commit logs is unconsistent, you should add a capital to Warn in meson: warn about possible uninitialized variables. I let many of these slip through to not bother you in the previous MRs, I hope you won't mind if I become a bit more pedantic about these ones from now on. :x

Beside that it looks great to me. :)

Unfortunately I can't merge it, I see Fast-forward merge is not possible. Rebase the source branch onto master to allow this merge request to be merged. message.

Compare with previous version

I'm happy to fix up commit messages when the code is alright. Did you look at the third patch and check that it doesn't paper over a deeper problem in HdyLeaflet?

I changed this repo to require fast-forwardable MRs, we can also enable the rebase button but I would prefer if people recheck their MRs if their outdated for the moment. O.k.?

These changes should be fine as you filled them up with "default" values. If bugs occur later, at least they will be consistent thanks to your changes. :)

I'm fine with that. It is convenient when the diversiond are completely unrelated but for the moment libhandy is low traffic and mostly just the two of us so it's fine.
