Update to wlroots 0.11.0

https://github.com/swaywm/wlroots/releases/tag/0.11.0

mentioned in merge request !153 (merged)

I went through @emersion 's upgrading checklist the other day and i think we have everything fixed up now. Clients like phosh need to understand the transform changes but that's a different matter.

@sebastian.krzyszkowiak do you have that somewhere on your todo list? I think we're basically the only ones not building against 0.11.0.

FWIW current wlroots master (b4ed8b3d7414ff6280098da811f873e5c5146d27) needs backported meson 0.54 (which backports cleanly with DEB_BUILD_PROFILES=nocheck and libwayland-server 1.18.0 (also a clean backport) but phoc seems to work with that then.

mentioned in issue #180

added wlroots 0.11.0 label

Running with 0.12.0 now since some time. There's a double-linked list crash (I'll keep poking at that one) that refuses to show under valgrind - apart from that it looks good (on intel). Byzantium has everything needed so i'd just leave amber-phone on 0.10.0 and only backport critical fixes but focus on byzantium otherwise since e.g. phosh needs more and more features from there too.

wlroots!81 (merged) basically fixes this for byzantium. I currently have no intend to do that for amber-phone too.

My current plan is to switch to wlroots 0.13.0 once it's released and drop support for older versions (and amber-phone).

we have 0.12.0 in landing since a while (which i'm using)

Yup, but the submodule is still at 0.10 and we still have some support code for 0.10. I think 0.13 will be a good moment to drop that.

my comment was meant affirmatve: i'll package 0.13.0 anyway when tagged upstream for Debian and i've been using 0.12.0 for months now without issues so that works for me.
