Port to meson build system

[tintou]

This is a meson port which might help to maintain PackageKit
(follow-up of #307)

Ninja dist seems to fail now:

ERROR: ['gtkdoc-mkhtml', '--path=/tmp/tmpoehjxhle/PackageKit-1.1.13/docs/api:/tmp/tmpx1bl9br8/docs/api', 'PackageKit', '../PackageKit-docs.sgml'] failed with status 6

Also, aren't meson options supposed to be using _ rather than - these days?

[tintou]

The meson style itself doesn't recommend anything regarding dashes and underscores
GNOME Builder uses underscores and Gtk uses dashes 🤷‍♂️
I'm okay with both so feel free to change to whatever you prefer

[hughsie]

GNOME Builder uses underscores

I was about to say that fwupd uses underscores, but now I see it uses both :/ -- I think there was some pressure for gnome-software to move from - to _, so I think that's probably what we should do here. Sorry!

[hughsie]

I think get the tests fixed on CI, and then we can merge this. Thanks.

@tintou: Are you planning on updating this / addressing the last comments? Two GNOME goals needs it: the gettext port and the Meson port. Would be nice to have that included in next PackageKit release. I could help if you don't have time to spend on this patch set any more.

[tintou]

@t-chaik Yeah, feel free to continue the work

[jjardon]

@t-chaik hey! did you have, by any chance, time to update this PR?

[t-chaik]

Haven't been able to find some time yet but that's still on my list. I'll try to have a look next week. Would that work for your release or would it be too late?

[t-chaik]

@hughsie: Do you mind giving me write access to the wip/tintou/meson branch? I can create a new PR if you prefer, up to you.

[Conan-Kudo]

@t-chaik Could you create a new PR initially? That would unblock showing us the code.

[hughsie]

@t-chaik i think a new PR is best.

[t-chaik]

Here: #332. I've pushed some fixes already but haven't look at the test failures yet. Will remove the WIP label once I believe it to be ready.

[hughsie]

I've fixed up a lot of the issues, so lets continue in #365 -- all comments there very welcome, thanks!
